| For a detailed list of all the changes refer to [[https://github.com/liblouis/liblouis/milestone/33?closed=1][the list of closed |
| issues]]. |
| |
| ** New features |
| - None |
| ** Bug fixes |
| - Fix a problem in the parsing of faulty unbalanced context |
| expressions. Thanks to Samuel Thibault. |
| - Fix a buffer overflow problem when ~output.length~ is larger than |
| ~input.length~. Thanks to Samuel Thibault. |
| - Fix an endless loop in the handling of computer braille. Thanks to |
| Bert Frees. |
| ** Braille table improvements |
| - Remove computer braille from Japanese Kantenji as it is not part of |
| the standard. Thanks to Kensaku Yoza. |
| - Bring Swedish tables up to date with the latest standard published |
| by Punktskriftsnämnden (the Swedish Braille Authority) in 2009. The |
| table for uncontracted braille was replaced and new tables for |
| (partially and fully) contracted braille have been added. Thanks to |
| David Renström from Insyn Scandinavia AB. |
| - Improvements to Hungarian (added more exceptions) and migration to |
| the ~nonumsign~ opcode thanks to Attila Hammer. |
| - Fixed a bug in the Ukrainian table that led to wrong translation of |
| some uppercase letters. Thanks to Andrey Yakuboy and Bert Frees. |
| - Augment the UEB grade 2 tables to resolve an ambiguity between lower |
| groupsigns and punctuation at the beginning of words by placing a letter |
| sign at the front of punctuation. This resolves an ambiguity between, for |
| example, "discount" and ".count". Thanks to Krzysztof Drewniak. |
| - Add a new table for /Chinese Common Braille Scheme/ which is a type |
| of braille used for spelling Mandarin Chinese. It is a variant of |
| the /Chinese Current Braille System/ but has more perfect marking |
| rules and produces less ambiguity than the latter. For more |
| information see the comments in ~zhcn-cbs.ctb~. Thanks to Cary-Rowen |
| and Frank. |
| - Updates to the Chinese bopomofo braille table thanks to Bo-Cheng |
| Jhan: |
| - Update braille patterns of some Chinese characters and phrases |
| - Add braille patterns for various Greek symbols |
| - Add "Math rules" section and the mixed number rule |
| - Add braille patterns for ☐ (⣏⣀⣹), ☑ (⣏⣿⣹), and ☒ (⣏⣭⣹) |
| - New table for Kinyarwanda braille thanks to Jake Kyle from Compass |
| Braille. |
| - New table for Luganda braille thanks to Jake Kyle from Compass |
| Braille. |
| - Improvements to the Russian contracted braille table |
| thanks to Andrey Yakuboy: |
| - Now prefixes "из" and "без" are correctly contracted |
| before hard sign (ъ). |
| - Fixed a contraction for word "кое-где", now it is contracted |
| according to rules. |
| - Other minor fixes and improvements. |

| * Noteworthy changes in release 3.22.0 (2022-06-06) |
| This is a major release. On the Braille tables side there is a new |
| table for German grade 2 with capitalization and there are updates to |
| the Dutch, German Hungarian, Punjabi, Russian, UK Braille Computer |
| Notation and Slovak tables. Christian added a new opcode to indicate |
| the end of a number where the number doesn't end at a space character. |
| Last but not least Samuel, Martin and Han have put a lot of work into |
| checking for and fixing memory problems. |
| |
| I'd like to thank everybody for helping to bring liblouis forward. |
| |
| For a detailed list of all the changes refer to [[https://github.com/liblouis/liblouis/milestone/32?closed=1][the list of closed |
| issues]]. |
| |
| ** New features |
| - Add a new opcode ~nonumsign~ that helps with indicating the end of a |
| number when it doesn't occur at the end at the end of a word such as |
| '123abc' for example. For more details see the documentation. Thanks |
| to Christian Egli. |
| ** Bug fixes |
| - Prevent a memory overflow in ~compilePassOpcode~ thanks to Martin |
| Gieseking. This was reported in [[https://github.com/advisories/GHSA-xrp8-mw8v-p6mq][CVE-2022-26981]] and should now be |
| fixed. |
| - Prevent processing of characters beyond the string end in |
| ~parseChars~ thanks to Martin Gieseking. |

| translation. Thanks to Jake Kyle. |
| - Improvements to the Russian and other Cyrillic tables thanks to |
| Andrey Yakuboy: |
| - Now all Russian based tables return braille Unicode braille by |
| default when forward translating, no need to include |
| ~ru-unicode.dis~ manually. |
| - French letters (æ, ë and ï) have been added to the Russian |
| literary braille table. |
| ** Other changes |

| * Noteworthy changes in release 3.21.0 (2022-03-07) |
| This release sees major updates for Hungarian and German. The Swiss |
| Library for the Blind, Visually Impaired and Print Disabled has agreed |
| to upstream their tables and Attila Hammer has adapted Hungarian to |
| the latest standard. A bug in numeric mode was fixed which should it |
| make more useful for languages other than UEB. Finally there are |
| fixes for Norwegian and Danish. |
| |
| I'd like to thank everybody for helping to bring liblouis forward. |
| |
| For a detailed list of all the changes refer to [[https://github.com/liblouis/liblouis/milestone/31?closed=1][the list of closed |
| issues]]. |
| |
| ** New features |
| - New table for German 6-dot computer braille thanks to the Swiss |
| Library for the Blind, Visually Impaired and Print Disabled |
| ** Bug fixes |
| - When numeric mode was enabled, i.e. when a table contains any of the |
| ~numericmodechars~, ~midnumericmodechars~ or ~numericnocontchars~ |
| opcodes, contraction was automatically disabled. This is required |
| for UEB but not necessarily so for other braille systems (as |
| mentioned in [[https://github.com/liblouis/liblouis/issues/615][issue 615]]). This has now been changed so that |
| contraction is only disabled if the ~nocontractsign~ has been |
| defined. Thanks to Christian Egli. |
| ** Braille table improvements |
| - Fixed emphasis, section sign and dash between numbers in Danish |
| tables thanks to Bue Vester-Andersen. |
| - Correct latin small letter sharp s in Norwegian thanks to Lars |
| Bjørndal and Dawn Renouf Bjørneby. |
| - Major improvements to German Braille thanks to the Swiss Library for |
| the Blind, Visually Impaired and Print Disabled |
| - Improvements to emphasis handling in German tables and greatly |
| extended test coverage. |
| - All the improvements from the tables formerly known as bidi tables |
| were merged in the main tables and are now used by both tables. |
| The bidi tables have been renamed to "detailed". Essentially the |
| detailed tables provide capitalized Braille which helps with the |
| back-translation. |
| - Upstream all improvements from the ~sbs-braille-tables~. |
| - Improvements to the Hungarian tables thanks to Attila Hammer. |
| - Improved back-translation, notably of words containing special |
| consonants like "szsz" or "ssz". |
| - Extended the Hungarian grade 1 "braille input" (back-translation |
| aided by special extra dot patterns). |
| - Implemented latest update to the Hungarian braille standard (for |
| example the characters "\" and "|" were changed). |
| ** Other changes |
| - Make ~autogen.sh~ work on MacOS, thanks to Ken Perry |
| ** Deprecation notice |
| - None |

| |
| * Noteworthy changes in release 3.20.0 (2021-12-06) |
| This is a major release. Not only in terms of table additions and |
| updates but also in the way the tables are written. Bert has replaced |
| the ~uplow~ opcode with a more generalized ~base~ opcode. This clears |
| up the path for a more generalized handling of emphasis and uppercase |
| characters. In the course of this simplification some bugs with |
| computer braille were discovered and fixed. |
| |
| On the Braille tables side there is a brand new table for braille |
| kanji and there are major updates to the Polish, Chinese, Russian |
| literary and the UEB tables. |
| |
| I'd like to thank everybody for helping to bring liblouis forward. |
| |
| For a detailed list of all the changes refer to [[https://github.com/liblouis/liblouis/milestone/30?closed=1][the list of closed |
| issues]]. |
| |
| ** New features |
| - There is an experimental new feature that allows a table writer to |
| write table macros. This feature is disabled by default. Macros are |
| a helpful tool for refactoring, however as it stands the feature is |
| not mature and might disappear in future releases. |
| - Add a new opcode ~base~ that associates a character with another |
| already defined character. Think of it as a generalized form of |
| ~uplow~. A typical use of this opcode is for defining a pair of |
| letters, a lowercase and the corresponding uppercase. |
| ** Bug fixes |
| - Fix a problem with the dot 7 capitalization indicator in computer |
| braille thanks to Bert Frees. |
| ** Braille table improvements |
| - New table for Kantenji (or "braille kanji", a Japanese braille |
| system) thanks to Kensaku Y. |

| patterns |
| - Add a math symbol '◊' (⠫⠓) |
| - Improvements to the Russian literary (uncontracted and contracted) |
| braille thanks to Andrey Yakuboy. |
| - If the dot sign ('.') is after digits at the beginning of a string, |
| the braille dot 6 isn't inserted between the last digit and the |
| dot. This is necessary for items' numbers of numbered lists. |
| - Back translation for French letters has been disabled because of |
| conflicts with punctuations. |
| - Back translation for Latin (mostly English and German) letters has |
| been improved. |
| - The definition of the 7/8 fraction (U+215E) has been fixed. |
| - Placement of spaces around math symbols has been improved |
| according to the Russian braille rules. |
| - The apostrophe sign ("'") and the right tick sign (u+2019) are |
| displayed correctly if they're in the end of a word (English, for |
| example). |
| - New contractions have been added and minor bugs have been fixed in |
| the Russian contracted braille table. |
| - New display table (~ru-brf.dis~) has been added. It adds support of |
| Braille ASCII for Russian and other Cyrillic tables. Thanks to |
| Andrey Yakuboy. |
| - Improvements to UEB thanks to James Bowden. |
| - Fixed placement of numeric indicator in letters dot numbers. |
| - Added more mathematical symbols. |
| - Added the four new allowed shortform extension words. |
| - Improvements to words starting with "dis(h)" and "cross(h)". |

| general ~base~ opcode. |

| * Noteworthy changes in release 3.19.0 (2021-09-06) |
| For this release Bert Frees has been hard at work to clean up the code |
| base. He fixed a few bugs one of which was causing memory corruption. |
| Others have contributed corrections to braille tables or even provided |
| new tables. For example there are now tables for Tshivenda and for |
| Russian contracted braille. |
| |
| I'd like to thank everybody for helping to bring liblouis forward. |
| |
| For a detailed list of all the changes refer to [[https://github.com/liblouis/liblouis/milestone/29?closed=1][the list of closed |

| section sign ('§' and '§§'), as well as numbersign ('#') before |
| numbers. In addition the letters a with acute, o with tilde, n with |
| long right leg and thorn are redefined. Phrases with capitals only |
| are know handled correctly. All thanks to Lars Bjørndal. |
| - Fix a problem with 'ç' in Northern Kurdish thank to Imam Kahraman |
| and Christian Egli. |

| This release stands in the tradition of small incremental improvements |
| that make it another fine and solid release. Andrey Yakuboy put in a |
| lot of work to improve Russian literary and computer braille. He also |

| * Noteworthy changes in release 3.16.1 (2020-12-01) |
| In the frenzy to ship the 3.16.0 release a little mishap slipped in. |
| The test suite contains an error and consequently doesn't pass. It was |
| promptly discovered and fixed by Samuel Thibault. So we present to you |
| the real, hopefully fixed 3.16 release. Let's name it 3.16.1. |
| |
| * Noteworthy changes in release 3.16.0 (2020-11-30) |
| This release is mostly the work of Bert Frees. He has put in a lot of |
| work and pushed some major improvements with regards to how emphasis |
| is handled (and how this is documented). He fixed a crash when reading |
| URLs using computer braille. He also worked with many contributors to |
| get their improvements in. So we have better support for UEB, Dutch, |
| Urdu, Malayalam, Arabic, Bashkir, Uzbek, Russian computer braille and |
| for EBAE. I'd like to thank everybody for helping to bring liblouis |
| forward. |

| - da-dk.dis :: This table has long been superseded by |
| ~da-dk-octobraille.dis~. |
| - da-lt.ctb :: This table was a step on the way to defining a Danish 8 |
| dot standard. The table was referring to an old Danish Braille |
| note-taker from the 80s and 90s, which is not used any more. |
| - fi1.ctb and fi2.ctb :: These tables are obsolete. Use |
| ~fi-fi-8dot.ctb~ instead. |
| |
| * Noteworthy changes in release 3.13.0 (2020-03-02) |
| A tremendous amount of work by lots of different people has gone into |
| this release. Bert Frees for example added new opcodes, fixed long |
| standing bugs (with emphasis and capitalization), made the |
| documentation more clear and helped table contributors bringing in |
| their improvements. Bue Vester-Andersen added major improvements to |
| Danish and German braille. This release also contains much improved |
| tables for Afrikaans, Russian computer braille, Urdu and Chinese. |
| |
| On a personal note I'd like to say that this is the 20th release of |
| liblouis shipped by the current release team Bert Frees and Christian |
| Egli. I hope we can continue to do so. |
| |
| For a detailed list of all the changes refer to [[https://github.com/liblouis/liblouis/milestone/23?closed=1][the list of closed |
| issues]]. |
| |
| ** New features |
| - The ~nocross~ opcode has been made into a prefix opcode, which means |
| that it can now be used in combination not just with the ~always~ |
| opcode but also with other translation opcodes such as ~begword~, |
| e.g. ~nocross begword sh 146~ for example. The old usage of the |
| opcode no longer works, see [[Backwards incompatible changes]]. |
| - Added a new opcode ~rependword~, needed to implement Malay |
| braille. Thanks to Bert Frees. |
| - Emphasis and capitals can now be marked correctly in more |
| cases. Thanks to Bert Frees. |
| - When ~begemphword~ (~begcapsword~) is defined but not |
| ~endemphword~ (~endcapsword~), use ~emphletter~ (~capsletter~) to |
| mark every character in an emphasized (capitalized) part that ends |
| in the middle of a word. |
| - When ~begemphword~ (~begcapsword~) and ~begemph~ (~begcaps~) are |
| both not defined, use ~emphletter~ (~capsletter~) to mark every |
| emphasized (uppercase) letter. |
| - ~capsnocont~ has no influence anymore on whether ~capsletter~ is |
| used for every uppercase letter or not, see [[Backwards incompatible |
| changes]]. |
| |
| ** Bug fixes |
| - Fix a crash on sparc64 thanks to Samuel Thibault. |
| - Fixed a bug where the ~inputPos~ array was not monotonically |
| increasing. This is a problem for language bindings that try to do |
| hyphenation based on this information. Thanks to Bert Frees. |
| - A couple of small Coverity fixes thanks to David King. |
| - Fix an infinite loop involving multipass rules and backtranslation |
| thanks to Bert Frees and Bue Vester-Andersen. |
| - Fix several problems in the Python bindings thanks to Leonard de |
| Ruijter, Łukasz Golonka and André-Abush Clause: |
| - Ensure that the mbcs encoding is always used to encode file path |
| on Windows, especially when 'Unicode UTF-8' feature is enabled. |
| - ~getTypeformForEmphClass~ was passed a decoded string on Python 3 |
| instead of an encoded one. |
| - The same applies to ~compileString~. We encoded the input string, |
| but never used that encoded one when passing it to liblouis. |
| - ~begemphword~ (~begcapsword~) and ~endemphword~ (~endcapsword~) are |
| now used for single letters within a word when ~emphletter~ |
| (~capsletter~) is not defined. |
| - For backward translation the returned input length is now equal to |
| the initial input length (as it is for forward translation) thanks |
| to Bert Frees. |
| |
| ** Braille table improvements |
| - Improvements to Afrikaans thanks to Christo de Klerk |
| - Fixed back translation of some lower words. |
| - Fixed several contraction errors where contractions are based on |
| pronunciation or occur where compound words join. |
| - Eliminated grade 1 indicator where a single letter follows a |
| single apostrophe to indicate an abbreviated word, e.g. 'k for ek. |
| - Corrected the use of the grade 1 indicator in grade 2 with signs |
| which would conflict with contractions, such as the trademark sign |
| that would conflict with the contraction of tussen. |
| - Fixed the back translation conflict between the UEB circle shape |
| indicator and words containing $= being the contraction for |
| "alge". |
| - Improvements to Russian computer braille table thanks to Andrey |
| Yakuboy. |
| - The table is now based on the Unicode character set. A lot of new |
| characters were added that aren't in KOI8-R, including Greek, |
| Hebrew, accented letters and so on. |
| - For special characters we now follow the definitions from other |
| software (JAWS, TSS, DBT) instead of following the American |
| standard. |
| - Improvements to Urdu Braille thanks to Jake Kyle |
| - Changed definition of \x0624 (Waw with hamza above) from dots 1256 |
| to dots 3-2456 following advice from proof reader. |
| - Added 2 character versions of letter plus diactric (previously |
| only the one character versions defined): |
| - Updates to the Danish Tables thanks to Bue Vester-Andersen: |
| - Fixed back-translation for some JAWS Braille drivers, which |
| deliver Unicode characters to Liblouis as input from a Braille |
| keyboard. |
| - Ensured proper use of letsign in connection with accented letters. |
| - Re-arranged and strengthened tests to include all Unicode |
| characters defined in the tables. |
| - Updates to the Chinese bopomofo braille table thanks to Bo-Cheng |
| Jhan, Coscell Kao and Victor Cai. |
| - New experimental German tables for grade 0 (Basisschrift) and grade |
| 1 (Vollschrift) that are more suitable for back-translation, thanks |
| to Bue Vester-Andersen. |
| - All capital letters are marked. |
| - Accented letters are translated using ~de-accents-detailed.cti~ to |
| make the translation as detailed as possible. |
| - Apostrophes and single quotation marks are translated the same. |
| |
| ** Other changes |
| - The documentation for the emphasis opcodes has been reworked and is |
| now much more clear and accurate thanks to Bert Frees. |
| |
| ** Deprecation notice |
| - Python 2 is [[https://www.python.org/dev/peps/pep-0373/][no longer maintained]] since the beginning of this year. |
| The current liblouis Python bindings work with both Python 2 and 3. |
| However the support for Python 2 will be dropped in the next release |
| (3.14) at the beginning of June 2020. If you have code that uses the |
| liblouis Python bindings with Python 2 then please refer to the |
| [[https://docs.python.org/3/howto/pyporting.html][official porting guide]] for help with migrating it. |
| |
| ** Backwards incompatible changes |
| - Since the ~nocross~ opcode has been made into a prefix opcode, it |
| must now be used in combination with another opcode. For example |
| ~nocross sh 146~ must now be written as ~nocross always sh 146~. |
| - The ~capsnocont~ opcode can not be used anymore to control whether |
| ~capsletter~ is inserted for every uppercase letter. This now |
| depends on whether ~begcaps~ and ~begcapsword~ are defined. |

| * Noteworthy changes in release 3.12.0 (2019-12-02) |
| This release contains major updates to the UEB, Afrikaans, Chinese, |
| Danish and Polish tables. Aside from that there have been many code |
| cleanups, such as the elimination of many global vars and bug fixes |
| such as an endless loop or a crash in ~lou_translate~. |
| |
| For a detailed list of all the changes refer to [[https://github.com/liblouis/liblouis/milestone/22?closed=1][the list of closed |

| |
| ** New features |
| None |
| ** Bug fixes |
| - Fix a memory leak when several tables are specified and some of them |
| that can't be resolved. Thanks to André-Abush Clause. |
| - Fix an endless loop with multipass rules where ~endReplace~ is |
| smaller or equal to ~startMatch~. Thanks to Bert Frees and Bue |
| Vester-Andersen. |
| ** Braille table improvements |
| - Punctuation corrections in Ethiopic Braille thanks to Dr. Tamru E. |
| Belay. |
| - Fixes to the Norwegian 8dot braille table in regards to 4 Sami |
| characters, capital and small letters S and Z with caron. Thanks to |
| Oddvar Øyan and Lars Bjørndal. |
| - Improvements to Afrikaans contracted braille thanks to Christo de Klerk |
| - Over 50 cases have been corrected where braille rules were not |
| correctly applied in words, mainly in those cases where |
| contractions depend on pronunciation; for example, ui or ie must |
| not be contracted in requiem. |
| - Corrected contraction errors caused by start or end of input not |
| properly taken into account. |
| - Words are no longer contracted into lower word contractions when |
| they are adjacent to lower punctuation, for example: "hier. |
| - Words are now contracted into their lower contractions when they |
| are adjacent to upper punctuation, for example: (hier. |
| - New draft table for Dutch 8-dot computer braille thanks to Leonard |
| de Ruijter. |
| - Updates to the Chinese bopomofo braille table thanks to Bo-Cheng |
| Jhan, Coscell Kao, 特種兵, 黃偉豪, and Victor Cai. |
| - Fixes to Polish grade 1, thanks to Łukasz Golonka |
| - Removes some unneeded ~midnum~ symbols from the Polish Grade 1. |
| - Fixes some symbols which weren't defined according to the |
| specification. |
| - Makes it possible to type dot from a braille keyboard. |
| - Adds Greek letters and some commonly used math operators to both |
| the Grade 1 and the computer braille table. |
| - Fix several conflicts in ~fr-bfu-comp68.cti~ with regards to the IPA |
| Unicode range. These had been especially noticed when |
| ~compbrlAtCursor~ mode flag was used. Thanks to André-Abush Clause. |
| - Major Improvements to contraction use in UEB thanks to James Bowden. |
| - Updates to the Danish Tables thanks to Bue Vester-Andersen: |
| - Added miscelaneous Unicode characters to 8 dots grade 1 and 2 |
| (accented letters, punctuation, arrows and some math signs). |
| Most of these characters have not been defined in the Danish |
| Braille standard. This implementation is purely experimental, |
| and the characters may be changed later. |
| - Updated the 6 dots tables with more Unicode characters |
| (no arrows or math signs). |
| - Corrected a bug in 8 dots grade 2, which resulted in the |
| "var" contraction not always being properly applied. |
| ** Other changes |
| - Make sure the log callback uses the same calling convention as all |
| the other exported functions. Thanks to Leonard de Ruijter. |
| - Fix a problem with Non-ASCII characters in file paths in the Python |
| bindings, thanks to André-Abush Clause. |
| - Eliminate some of the globals variables thanks to Bert Frees. |
| - The display and the translation are now separated at least |
| internally, thanks to Bert Frees. As a reminder, there are two |
| phases to a braille conversion: |
| - translation :: liblouis uses the rules in the translation table to |
| convert characters to dots |
| - display :: display the dots as characters. Usually liblouis uses |
| the characters defined in display rules (in display |
| tables) but as a fallback it uses mappings defined in |
| the translation table, e.g. letter rules. |
| - No longer install ~lou_compare~, a tool that is used to run |
| regression tests for UEB. As it is only run during testing it will |
| no longer be installed by default on a users machine. |
| - Remove a hidden feature of ~lou_translate~ that would cause it to |
| crash if passed an invalid file name. Thanks to Christian Egli. |
| - Raise an error if a dot pattern can not be displayed instead of |
| silently ignoring it thanks to Bert Frees. |

| * Noteworthy changes in release 3.11.0 (2019-09-02) |
| A tremendous amount of work by Dave Mielke and Bert Frees has gone |
| into this release. They have improved liblouis for use on note taker |
| devices, for backwards translation and a number of languages. Many |
| other contributors (listed below) have also helped in fixing bugs and |
| improving braille tables, such as Dutch, Mongolian, Polish, Ancient |
| Greek, Danish, Irish, Chinese, and American Braille Computer Code. |
| |
| For a detailed list of all the changes refer to [[https://github.com/liblouis/liblouis/milestone/21?closed=1][the list of closed |
| issues]]. |
| |
| ** New features |
| - Enable ~always~ rules with a single character and a single braille |
| cell for back-translation. Thanks to Bue Vester-Andersen. |
| - Implement ~noUndefined~ mode for forward translation, thanks to Dave |
| Mielke. |
| - Use fallback braille representations (NABCC) for rendering undefined |
| characters in hexadecimal notation, thanks to Dave Mielke. |
| - Always render undefined characters, also ASCII characters, in |
| hexadecimal notation. |
| - Add a new metadata field ~index-name~ for selecting a table from a |
| list fast and efficiently. It has the most important information |
| first and no redundant information. It should look nice when sorted. |
| This in contrast to the existing ~display-name~ field which is for |
| describing a table accurately and should sound good. Thanks to Dave |
| Mielke and Bert Frees. |
| |
| ** Bug fixes |
| - Don't let a caps passage end on a word with no letters. Thanks to |
| Bert Frees. |
| - Handle word resets in the last word of an caps or emphasis passage |
| if the end indicator was placed before the word. Thanks to Bert |
| Frees. |
| - Never convert to lowercase if ~capsletter~ is not defined. Thanks to |
| Bert Frees. |
| - Fix position mapping for back-translation when ~noUndefined~ mode is |
| active. Thanks to Dave Mielke. |
| - Fix bug where a translation would hang on words that match both a |
| ~nocont~ and a ~repeated~ rule. Thanks to Dave Mielke. |
| - Fix bug where the effect of ~capsnocont~ would leak to the next word |
| if that word starts with a capital. Thanks to Bue Vester-Andersen. |
| |
| ** Braille table improvements |
| - Fix an issue with ordinal numbers inside caps passages in Dutch |
| braille. Thanks to Bert Frees. |
| - Improved back-translation for Mongolian thanks to Angaragerdene. |
| - Fixes to Polish grade 1 and Polish computer braille thanks to Łukasz |
| Golonka. |
| - Improvements to Ancient Greek braille, which has been renamed "Greek |
| international braille". A version with composed accents is made |
| available as a .uti table. Thanks to Dave Mielke and Μαρια |
| Γεωργακαράκου (Maria Georgakarakou). |
| - Various improvements to modern Greek thanks to Dave Mielke. |
| - Improvements and fixes to Spanish contracted braille. Details in |
| #741. Thanks to Juan Pablo Bello. |
| - Improvements and fixes to the Danish tables. Thanks to Bue |
| Vester-Andersen. |
| - Add a display table to match Word CX which is used in Norway and |
| Sweden, and maybe also in other countries thanks to Lars Bjørndal. |
| - Fix handling of colon within number in Dutch braille, thanks to Jake |
| Kyle. |
| - Fix translation of bullet and dot operators in Dutch braille, thanks |
| to Paul Rambags |
| - Added North American Braille Computer Code table (~en-nabcc.utb~) |
| which is the counterpart of the ~text_nabcc.dis~ display table. |
| Thanks to Dave Mielke. |
| - Add support for the International Phonetic Alphabet (IPA) to the |
| Chinese bopomofo braille table, thanks to Hurt Huang and Sponge |
| Jhan. Various improvements, including dot patterns and test cases, to |
| the Chinese bopomofo braille table, thanks to Sponge Jhan. |
| - Unified English Braille no longer displays a single underscore when |
| multiple underscores are in the text, thanks to André-Abush Clause. |
| - Update to Afrikaans uncontracted braille and new table for contracted |
| braille. Thanks to Christo de Klerk and Greg Kearney. |
| - Update Irish braille (contracted and uncontracted) to the May 2019 |
| version of the specification, thanks to Ronan McGuirk |
| |
| ** Other changes |
| - The python wrapper now encodes and decodes strings to/from UTF-16 |
| and UTF-32 using the surrogatepass error handler. This ensures that |
| single UTF-16 surrogate characters are processed correctly by the |
| wrapper and don't raise an encoding/decoding error. Thanks to |
| Leonard de Ruijter. |
| - Metadata keys and values are now case insensitive, thanks to Dave |
| Mielke. |
| - Remove ~unicodedefs.cti~. It was obsolete and never meant to be |
| included by any tables. Instead use the online references as |
| mentioned in the documentation now. See also #696. |
| - ~lou_checkyaml~ test reporting has been improved, thanks to Bert |
| Frees. For example it now has a ~--verbose~ option so that printing |
| of expected failures can be enabled. |
| - Hyphenation tables have been removed from tables except those needed |
| for ~nocross~ rules, thanks to Bert Frees. |
| |
| The idea is that the caller (for example ~odt2braille~ or |
| ~liblouisutdml~) should be able to decide for themselves which |
| hyphenation table to use. The case in which a table contains nocross |
| rules is an exception. In this case the hyphenation patterns are a |
| real part of the table. Because it is not recommended to append an |
| own hyphenation table in this case, a ~#-has-nocross~ metadata field |
| was added to indicate that a table contains nocross rules. |
| - ~lou_hyphenate~ can now handle more than just words (sequences of |
| letters), e.g compound words, thanks to Bert Frees. |
| |
| ** Deprecation notice |
| - The ~noUndefinedDots~ mode has been renamed to ~noUndefined~. For |
| backwards compatibility ~noUndefinedDots~ is still available in the |
| header file and in the Python bindings, as an alias for |
| ~noUndefined~. |
| |
| ** Backwards incompatible changes |
| None |

| * Noteworthy changes in release 3.10.0 (2019-06-03) |
| This release comes across as quiet, containing just the usual |
| assortment of braille table improvements, cleanups, bug fixes and the |
| classic buffer overflow patches. But beware, a lot has happened behind |
| the scenes. Bert and Davy have been adding a new opcode to handle |
| special emphasis situations. A number of annoying restrictions with |
| regards to names, such as class names have been removed thank to Bert. |
| And lastly also thanks to Bert it is now possible to define inline |
| display tables in your YAML tests. |
| |
| For a detailed list of all the changes refer to [[https://github.com/liblouis/liblouis/milestone/20?closed=1][the list of closed |
| issues]]. |
| |
| ** New features |
| - Add a new opcode ~emphmodechars~. Thanks to Bert Frees and Davy |
| Kager. |
| |
| ** Bug fixes |
| - Remove memoization in ~checkAttr~. It wasn't implemented correctly, |
| caused some weird bugs and probably didn't do much for performance. |
| Thanks to Bert Frees. |
| - Fix multiple buffer overflows in ~compilePassOpcode~. Thanks to |
| Cheng Wen for the report and to Christian Egli for the fix. |
| - Fix a build problem when building without libyaml thanks to Bert |
| Frees. |
| |
| ** Braille table improvements |
| - Added modified letters to UEB thanks to Mike Gray. |
| - Complete overhaul of the U.S. six-dot computer braille tables to |
| align with the CBC standard thanks to Timothy Wynn. There is now a |
| sub-table for EBAE (~en-us-compbrl.uti~) and a stand-alone table |
| (~en-us-comp6.ctb~). |
| - Conforms to the CBC standard from BANA for character definitions |
| that differ from the 8-dot ASCII braille (11 punctuation marks). |
| - Added rules for braille indicators, emphasis indicators, and |
| isolated lower-cell signs to the stand-alone table. |
| - Uncontracted and contracted EBAE tables no longer use dot 7 when |
| in computer braille mode. |
| - ~en-us-compbrl.ctb~ was deleted because it was identical to |
| ~en-us-comp6.ctb~. |
| - Update Bopomofo-based Chinese Braille thanks to Sponge Jhan |
| - Correct various dot patterns of Chinese characters. |
| - Add more known pattern exceptions of Chinese characters. |
| - Apply ~word~ opcode to 倔 and 据. |

| can be used in translation rules, thanks to Bert Frees. |
| - Remove some code duplication in ~pattern.c~ thanks to Bert Frees |
| - It is now also possible to define inline tables when a display table |
| has been defined thanks to Bert Frees |
| - Nightly snapshots of liblouis are now also built for win64 thanks to |
| Bert Frees |

| |
| * Noteworthy changes in release 3.9.0 (2019-03-04) |
| This release has seen a tremendous amount of work by Bert Frees. He |
| was instrumental in pushing the improvements for Latvian, Norwegian |
| and Slovenian. But most prominently he pushed the big change for space |
| and control character handling through the door. These characters are |
| now no longer hard coded in liblouis. This should solve a few long |
| standing issues. Other than that there is the usual assortment of code |
| improvements and cleanups. |
| |
| For a detailed list of all the changes refer to [[https://github.com/liblouis/liblouis/milestone/19?closed=1][the list of closed |
| issues]]. |
| |
| ** New features |
| - None |
| |
| ** Bug fixes |
| - Fix a problem in the callback registration in the Python bindings |
| thanks to Leonard de Ruijter. |
| - Fixed memory leaks created by block scope compound literals thanks |
| to Martin Gieseking. |
| - The hard coded rules dealing with white space have been replaced |
| with a normal table that is included in all tables. This fixes a |
| number of bugs to do with space and control characters. This (big) |
| change has been brewing for a couple of releases and has finally |
| landed. Thanks to Christian Egli and Bert Frees. |
| |
| ** Braille table improvements |
| - Major extension of the German 8 dot computer braille table thanks to |
| Ali-Riza Ciftcioglu. For example the Euro sign or quote characters |
| are finally defined. |
| - Fix a few issues with Hungarian grade1 and grade2 Braille thanks to |
| Attila Hammer. |
| - Various improvements to Norwegian thanks to Lars Bjørndal, Jostein |
| Austvik Jacobsen, Ammar Usama and Bert Frees. |
| - Updates to Bopomofo-based Chinese Braille thanks to Sponge Jhan: |
| Improved Braille representation of Chinese characters, and rewritten |
| Kana rules using multipass statements. |
| - Implement the new Slovenian Braille standard thanks to Robert Merič |
| and Bert Frees. |
| - Updates to Latvian Grade 1 Braille thanks to Artis Raugulis and Bert |
| Frees. |
| - Fixes to English, U.S. Grade 2 (ABAE) thanks to jdatray. |
| |
| ** Other changes |
| - Don't search for tables in ~/usr/local/share/liblouis/tables~ (or |
| the Windows equivalent) if ~LOUIS_TABLEPATH~ is set. |
| - The log levels in ~liblouis.h~ are no longer exposed as ~LOG_FOO~ |
| but instead are now prefixed. So ~LOG_WARN~ becomes ~LOU_LOG_WARN~ |
| for example to issue a warning from a C program using liblouis. The |
| actual values remain the same, so the ABI remains stable. |
| |
| ** Deprecation notice |
| - The ~locale~ opcode was never implemented and was just silently |
| ignored. It is now removed from the tables and a warning will be |
| issued if it is found in a table. |
| |
| ** Backwards incompatible changes |
| |
| ** New, renamed or removed tables |
| *** New |
| - None |

| |
| * Noteworthy changes in release 3.8.0 (2018-12-03) |
| The major focus of this release is on braille table updates. There are |
| major updates to German, Arabic, Chinese, Turkish, Dutch, Czech, |
| Latvian, Spanish and Ethiopic. Some of these new tables have only been |
| possible because Bert Frees fixed some nasty long standing bugs behind |
| the scene. Also there is the usual assortment of code improvements and |
| cleanups. |
| |
| For a detailed list of all the changes refer to [[https://github.com/liblouis/liblouis/milestone/18?closed=1][the list of closed |

| now as they are based on ~lou_maketable~. As they now work for any |
| locale (be it Switzerland or Germany) they have been merged into one |
| set of tables for the different grades. Thanks to Christian |
| Waldvogel. |
| - New table for Arabic contracted braille thanks to Ikrami Ahmad. |
| - New table for Arabic computer braille thanks to Ikrami Ahmad. |

| * Noteworthy changes in release 3.7.0 (2018-09-03) |
| This release implements major improvements for back-translation thanks |
| to concerted efforts by Bue Vester-Andersen, Bert Frees, Timothy Lee |
| and others. In particular the input/output positions are now correct |
| also for back-translation. There are new and improved Chinese Braille |
| tables and some long awaited improvements to UEB. The release also has |
| some code cleanups and documentation improvements. |
| |
| For a detailed list of all the changes refer to [[https://github.com/liblouis/liblouis/milestone/17?closed=1][the list of closed |
| issues]]. |
| |
| ** New features |
| - Added a new opcode ~midendnumericmodechars~. Characters defined with |
| this opcode can appear in the middle or at the end of a number |
| without canceling numeric mode. Thanks to Bue Vester-Andersen. |
| |
| ** Bug fixes |
| - Fix another stack-based buffer overflow in input parsing reported by |
| Henri Salo thanks to Christian Egli. |
| - Fix input/output positions for back-translation. Thanks to excellent |
| bug reports and patches by Timothy Lee, Bert Frees heroically sat down and |
| reworked the handling of the input/output positions for |
| back-translation. This solves numerous issues with backward |
| translation. |
| - The returned ~inlen~ and ~outlen~ now always match thanks to the |
| above work on input/output positions by Bert Frees. |
| - Major improvements in the back-translation of capitalized words |
| (~capsword~) in conjunction with punctuation and numbers. Thanks to |
| Bue Vester-Andersen |
| - Fixed a problem in the back-translation of numbers in conjunction |
| with punctuation and letters. Thanks to Rimas Kudelis and Bue |
| Vester-Andersen |
| - Fix a buffer overflow in ~matchCurrentInput~. Thanks to Hongxu Chen |
| for reporting and to Christian Egli for fixing it. |
| |
| ** Braille table improvements |
| - Danish grade 2 tables: Reduced hyphenation to only the hyphens |
| necessary for correct Braille translation. Replaced the longer rules |
| with hyphenation for better cursor positioning. Corrected some words. |
| Thanks to Bue Vester-Andersen. |
| - New Chinese Mandarin Braille Codes (Grade 1) and (Grade 2) thanks to |
| Sunian Loomee. The first one is for Chinese Common Braille, commonly |
| known as the old Braille where a Chinese character is composed of |
| three Braille Symbols, consonants, vowels and tones. The second |
| table is for Chinese double spelling Braille, commonly known as the |
| new Braille where Chinese character is composed of two Braille |
| Symbols, consonants and vowels, ( the tones are included in vowels ). |
| - Major update to the Urdu tables thanks to Jake Kyle. |
| - Back-translation of numbers in Latvian, Polish, Portuguese, Serbian, |
| and Swedish has been fixed thanks to Bue Vester-Andersen. |
| - Improvements to UEB such as handling of /BLT/, /BLVD/ and /LLC/, |
| number sign placement, final-letter groupsign usage and final-letter |
| back-translation thanks to Mike Gray. |
| - Significant changes to Bopomofo-based Chinese Braille. Among other |
| things there is now complete the support of /CJK Unified Ideographs |
| Extension A/ and some symbols were added for Nemeth. Thanks to |
| Sponge Jhan and 黃偉豪. With this change we can now properly handle |
| duoyinzi, Chinese words that have more than one pronunciation. The |
| granularity of the cursor movement can now reflect positions of all |
| Chinese characters. |
| |
| ** Other changes |
| - Added documentation of opcodes which were previously introduced as |
| part of the UEB work. Thanks to Bue Vester-Andersen. |
| - Test suite improvements: In addition to checking the translation the |
| tests now also check if the provided ~inlen~ is the same as the |
| returned ~inlen~ and retry the test with a larger output buffer. |
| - Fix a problem in the Makefiles that prevented liblouis from being |
| built with automake 1.16. This is fixed now thanks to a patch from |
| Samuel Thibault. |
| - Removal of the code for the /scripting language/ for multipass |
| opcodes. This code was originally introduced in 2012 but never |
| documented. Consequently it was never used. Meanwhile the original |
| code for multipass opcodes was much improved. So there is no more |
| need for this (duplicate) code and we are removing it. |
| - The nightly snapshots of pre-built windows binaries are now built |
| with UCS4 enabled. |

| * Noteworthy changes in release 3.6.0 (2018-06-04) |
| This release contains the usual assortment of braille table |
| improvements, cleanups and bug fixes. The most prominent change is the |
| refactoring of the call APIs by Bert Frees that makes the code much |
| more manageable and solid and will help us in the future to evolve the |
| library. |
| |
| For a detailed list of all the changes refer to [[https://github.com/liblouis/liblouis/milestone/16?closed=1][the list of closed |
| issues]]. |
| |
| ** New features |
| - Add metadata fields =name= and =display-name= to tables thanks to |
| Bert Frees. The =name= contains a description of the table in the |
| native language. =display-name= contains an English description. |
| - YAML test enhancements |
| - You can now test both forward and backwards translation with in |
| the same YAML file and for the same set of tables tests thanks to |
| Bue Vester-Andersen. See the documentation for the |
| ~bothDirections~ testmode. |
| - Add =maxOutputLength= option in YAML tests. |
| |
| ** Bug fixes |

| by Henri Salo and Edward-L thanks to Christian Egli (CVE-2018-11577, |
| CVE-2018-11683, CVE-2018-11684 and CVE-2018-11685). |
| |
| ** Braille table improvements |
| - Fix some forward- and back-translation errors in Unified French Grade |
| 2 thanks to André-Abush Clause. |
| - Updates to the Simplified-Chinese Braille Translation Table thanks |
| to Roshanson |
| - Added many polygraphs to distinguish different meanings of a word |
| - Letter identifiers have been modified. In China's school for the |
| blind, when many visually impaired students learn, the lowercase |
| letters often do not have to mark the identifiers deliberately. So |
| in this version, we this item has been deleted. |
| - Fixed a bug in the braille code that revises the space and 0 |
| - Updates to Bopomofo-based Chinese Braille Table thanks to Bo-Cheng Jhan |
| - Redefine some Chinese words and phrases |

| - Combine =emphasisBuffer= and =transnoteBuffer= |
| - Group match related vars in a struct =PassRuleMatch= |
| - Remove dead code |
| - Fixed many warnings thanks to Christian Egli |
| |
| ** Deprecation notice |
| - The =mode= parameter in =lou_dotsToChar= never had any effect and is |
| now deprecated. |
| - In 2012 a new way to specify the test and action part in context and |
| multipass opcodes was introduced. It was never documented and has no |
| known usage in the wild. However it opens up the attack surface to |
| the table parsing code. Therefore it is deprecated and will be |
| removed in the next release. |

| |
| * Noteworthy changes in release 3.5.0 (2018-03-05) |
| This release has a number of Braille table improvements, cleanups and |
| meta data enhancements. The most prominent new feature however is |
| probably the much improved test coverage. This has helped in tracing |
| and fixing a number of long standing bugs. |
| |
| For a detailed list of all the changes refer to [[https://github.com/liblouis/liblouis/milestone/15?closed=1][the list of closed |
| issues]]. |
| |
| ** New features |
| - The same name can now be used in more than one ~class~ rule. The |
| effect is that both set of characters become part of that one class. |
| |
| ** Bug fixes |
| - Fix a regression in inputPositions thanks to Bert Frees |
| - Treat characters within the range ~compbrlStart~ and ~compbrlEnd~ as |
| a special case. This fixes many if not most of the problems with |
| cursor position and the ~compbrlAtCursor~ mode. Thanks to Dave Mielke. |
| - Fix ~swapdd~ opcode thanks to Bert Frees |
| - Fix negation of attribute matcher in multipass expressions thanks to |
| Bert Frees |
| |
| ** Braille table improvements |
| - Add a display table that maps braille dots to brl/brf character set. |
| For an in depth explanation see the corresponding [[https://github.com/liblouis/liblouis/issues/503][github issue]]. |
| Thanks to Rimas Kudelis |
| - Major Improvements to Unified French Grade 2 thanks to André-Abush |
| Clause |
| - Fix braille number input for Greek Braille thanks to Dave Mielke |
| - Add a fix for "phad" according to UEB Rule 10.7.3 thanks to Anthony |
| Tibbs |
| - Updates to the Urdu tables thanks to Jake Kyle from Compass Braille |
| - Updates to the Chinese braille table (~zh-tw.ctb~) thanks to |
| Bo-Cheng Jhan |
| - ~IPA.utb~ now contains a more complete list of phonetic symbols, |
| including some that might conflict with other tables. For this |
| reason it is not suitable for inclusion in other tables. A separate |
| table ~IPA-unicode-range.uti~ has been added for this |
| purpose. Thanks to Ludovic Oger. |
| - The Mongolian table has been improved and there is now also support |
| for grade 2 thanks to Tsengel Maidar. |
| - Minor updates to the Danish tables thanks to Bue Vester-Andersen |
| - Fix back translation of numbers in Dutch, Finnish and Canadian |
| French, thanks to Leonard de Ruijter. |
| - New table for Ukrainian thanks to Sergiy Moskalets. |
| |
| ** Other changes |
| *** Improved documentation |
| - Extend the documentation on multipass opcodes. Thanks to Dave Mielke |
| and Christian Egli. |
| - Remove the deprecation note of the '=' dots operand. While there are |
| still problems with back-translation we will not remove support for |
| it. See also the discussion in the [[https://github.com/liblouis/liblouis/issues/500][github issue]]. |
| |
| *** Improved meta data information in tables |
| The meta data in the tables such as locale, contraction grade, etc has |
| been improved and is now also used when testing from a YAML test. |
| Thanks to Bert Frees. |
| |
| *** Major overhaul of the YAML test suite |
| **** Support for proper testing of cursor positions |
| Due to problems in the cursor position computation the YAML test |
| suite was improved to support proper testing of cursor position also |
| in combination with input, output position and modes. In essence all |
| of the liblouis API is now supported and can be tested via the YAML |
| tests. Thanks to Christian Egli. |
| |
| **** Support for table selection via meta data query |
| The tables to be tested can now be specified via a meta data query in |
| addition to specifying them by filename. See the documentation for |
| more details. Internally the YAML tests have been split up into tests |
| that test the braille translation for a particular locale (now located |
| in ~tests/braille_specs~) and tests that check a specific feature of |
| liblouis. Thanks to Bert Frees. |
| |
| ** Deprecation notice |
| None |
| |
| ** Backwards incompatible changes |
| - The translation mode ~comp8Dots~ has been removed as it was never |
| really implemented anyway |
| - Support for the ~pass1Only~ flag has now been removed. Thanks to Bue |
| Vester-Andersen. |
| - The old UEB tables ~UEBC-g1.ctb~ and ~UEBC-g2.ctb~ have been removed |
| as the have been superseded by ~en-ueb-g1.ctb~ and ~en-ueb-g2.ctb~. |
| - The french tables ~fr-2007.ctb~, ~fr-fr-g1.utb~, ~fr-fr-g2.ctb~, |
| ~fr-ca-g1.utb~ and ~fr-ca-g2.ctb~ have been removed. Use |
| ~fr-bfu-comp6.utb~ for 6 dots literary, ~fr-bfu-comp8.utb~ for 8 |
| dots computer and ~fr-bfu-g2.ctb~ for contracted braille instead. |

| * Noteworthy changes in release 3.4.0 (2017-12-04) |
| This release brings together a lot of work by lots of different |
| people. Probably the most prominent fix is the work on output |
| positions by Bue and Bert. NVDA should benefit from this. Then there |
| are new and massively improved tables like the Lithuanian 6-dot table |
| by Rimas or the improved back-translation for French by Michel and |
| André-Abush to name just a few. There are too many contributors to |
| name them here, thanks to them all. |
| |
| For a detailed list of all the changes refer to [[https://github.com/liblouis/liblouis/milestone/14?closed=1][the list of closed |
| issues]]. |
| |
| ** New features |
| - Add support for ~inputPos~ and ~outputPos~ checking in |
| ~lou_checkyaml~ thanks to Bue Vester-Andersen. See the manual for |
| details and examples. |
| ** Bug fixes |
| - output positions (~outputPos~) are now calculated based on input |
| positions (~inputPos~) thanks to Bert Frees. This avoids a whole |
| class of bugs that previously plagued the output positions. This fix |
| also obviates the need for the ~pass1Only~ flag. See below for the |
| deprecation notice. |
| ** Braille table improvements |
| - Addition of Nemeth and Kangxi radical characters and other |
| improvements to Chinese braille (~zh-tw.ctb~) thanks to Bo-Cheng |
| Jhan and 黃偉豪. |

| Such and André-Abush Clause |
| ** Other changes |
| *** Improved documentation |

| |
| * Noteworthy changes in release 3.1.0 (2017-03-06) |
| An influx of new contributors have made sure that liblouis continues |
| to improve. Back translation has seen major improvements, there are |
| some additional modes to help screen readers, for many tables meta |
| data has been added, the Python bindings are more robust, Windows |
| support has been improved, the YAML test suite has been generalized |
| and as usual new and improved braille tables have been included. On |
| the licensing front we managed to get almost all tables re-licensed to |
| LGPLv2.1+. |
| |
| ** New features |
| *** Meta data |
| Most of the translation tables now contain meta data. This makes them |
| discoverable. Programs can use the lou_findTable function to find a |
| table based on a query. |
| |
| *** noUndefinedDots mode |
| Add a noUndefinedDots mode to disable the output of dot numbers when |
| back-translating undefined patterns. Thanks to James Teh. |
| |
| When back translating input from a braille keyboard cell by cell, it is |
| desirable to output characters as soon as they are produced. |
| Similarly, when back translating contracted braille, it is desirable to |
| provide a "guess" to the user of the characters they typed. To achieve |
| this, liblouis needs to have the ability to produce no text when |
| indicators (which don't produce a character by themselves) are not |
| followed by another cell. This works already for indicators liblouis |
| knows about such as capital sign, number sign, etc., but it does not |
| work for indicators which are not (and cannot be) specifically defined |
| as indicators. For example, in UEB, dots 4 5 6 alone produces the text |
| "\456/". Setting the noUndefinedDots mode suppresses this dot number |
| output. |
| |
| *** partialTrans mode |
| Add a partialTrans mode to specify that back-translation input should |
| be treated as an incomplete word. Thanks to James Teh. |
| |
| If this mode is set, rules that apply only for complete words or at |
| the end of a word will not take effect. This is intended to be used |
| when translating input typed on a braille keyboard to provide a rough |
| idea to the user of the characters they are typing before the word is |
| complete. |
| |
| *** YAML test framework |
| The YAML framework has been extended and is much more useful now. You |
| can test multiple tables within one YAML file, you can define test |
| tables directly inline and you can test multiple tables using the same |
| test data. Refer to the documentation for the details. |
| |
| If really not wanted the YAML tests can be disabled by specifying |
| ~configure --without-yaml~. |
| |
| ** Bug fixes |
| - Fixes implicit declaration of 'pattern_check' thanks to Reiner Dolp |
| - Fix a stackoverflow crash on applications with smaller stack size. |
| Thanks to Victor Montalvão. |
| - Fix the \v escape sequence. Thanks to Davy Kager. |
| - The Python bindings now give a helpful error if liblouis has been |
| compiled with a different character size than Python. Thanks to Matt |
| Wenn. |
| - Massive bug fixes in multipass rules. Dave Mielke has done a |
| tremendous job improving the multipass machinery also in the |
| context of back-translation. Where needed nofor/noback has been |
| added to the multipass rules. |
| |
| ** Other changes |
| - Improvements to the Emacs mode for editing liblouis tables thanks to |
| Christian Egli |
| - Documenting lou_charSize thanks to Reiner Dolp |
| - Support for relative table paths in the tests. This will make sure |
| you always know which table a test actually uses. |
| - Infrastructure to build windows binaries in a Docker container, |
| thanks to Bert Frees |
| |
| ** Braille table improvements |
| - UEB improvements, thanks to Mike Gray |
| - Fixed apostrophe and back translation |
| - Added rules for Unicode apostrophe handling |
| - Improvements to UEB and Nemeth math |
| - Complete overhaul of Lithuanian 8-dots table, thanks to Rimas |
| Kudelis |
| - New Urdu 6 Dot Grade 1 and 2 Braille tables thanks to Jake Kyle |
| - Improvements to Italian 8 dots computer braille, thanks to Simone |
| Dal Maso. |
| - New table ~unicode-braille.utb~ that helps to back translate braille |
| input to Unicode braille output, thanks to Leonard de Ruijter. |
| - Improvements to the Chinese braille table thanks to Coscell Kao. |
| - New Turkish braille table for grade 1 that should replace the |
| old ~tr.ctb~ table, thanks to Arend Arends. |
| - New Persian grade 1 table and 8-dots computer table thanks to |
| Mohammadreza Rashad. |
| - New table for the International Phonetic Alphabet thanks to Ludovic |
| Oger |
| - Fixes for the French 6 and 8 dots tables thanks to Michel Such. Some |
| errors have been fixed and many Unicode characters have been added. |
| - Add an extended 8-dot computer braille table for U.S. English thanks |
| to Davy Kager. The table is tailored for use on Windows (CP-1252) |
| and uses dot patterns from Windows screen readers, but should be |
| useful on other platforms too. |
| - New Greek table that is better than the existing Greek Grade 1 |
| Braille Table (gr-gr-g1.utb) thanks to Dave Mielke. |
| - Improved number back-translations on fr-fr-g1 and vi-g1 tables |
| thanks to Victor Montalvao. |
| - New Chinese Braille table for use in the mainland of China thanks to |
| Kaifang Bao of RejoinTech. |
| - The Black Circle character is commonly used for displaying password |
| characters. The absence of its definition leads to users not being |
| able to know how many characters were typed in such fields. This has |
| been improved for many tables thanks to Victor Montalvao. |
| |
| ** License changes |
| - DocArch has agreed to re-license their tables, so we have 8 more |
| tables under the LGPLv2.1+. |
| |
| ** Backwards incompatible changes |
| - The naming in the YAML test framework has changed slightly from |
| `tables:` to `table:`. |
| |
| * Noteworthy changes in release 3.0.0 (2016-07-14) |
| This is the biggest release of liblouis in years. The major news are |
| that we now have proper support for UEB and secondly that liblouis is |
| now licensed under [[https://www.gnu.org/licenses/old-licenses/lgpl-2.1.html][LGPLv2.1+]]. |
| |
| In order to support UEB the internals of liblouis have seen a major |
| rewrite. New Opcodes have been added to support the requirements for |
| proper UEB for example for emphasis handling or to handle proper |
| translation of numbers. Changes to the opcodes are described in the |
| documentation. Some of these changes are not backwards compatible. All |
| tables that come with liblouis have been migrated. If you have private |
| tables look at the section on upgrading from previous versions in the |
| [[https://github.com/liblouis/liblouis/wiki/Emphasis-Opcodes#upgrade-from-previous-versions][wiki]]. |
| |
| This release also changes the C API. External applications will have |
| to adapt the way they call liblouis. In particular the typeform |
| parameter has changed. |
| |
| The license of the library and most of the tables has been changed to |
| LGPLv2.1. For a detailed list which tables are still in the process of |
| migrating the license refer to the [[https://github.com/liblouis/liblouis/wiki/Licensing-of-liblouis-tables][wiki page about the license change]]. |
| |

| - support translation of numbers according to the rules of UEB. |
| - Capitalization is now handled just like emphasis. |
| - support for numeric mode |
| - UTF-8 support for all tools thanks to Christian Egli. |
| - The YAML tests now allow for an optional test description. See the |
| documentation for more details. |
| - Add ~lou_checkTable~ and ~lou_getTypeformForEmphClass~ to the C API |
| and to the Python bindings |
| ** Bug fixes |
| - Stop buffer overrun in ~lou_getProgramPath~, and also free memory |
| after usage. Thanks to Michael Curran. |
| ** Other changes |
| - The license of the library and most of the tables has been changed |
| to [[https://www.gnu.org/licenses/old-licenses/lgpl-2.1.html][LGPLv2.1+]]. |
| - Improvements to the test suite: |
| - Output is printed to ~stderr~. This helps with locating errors when |
| testing with the YAML test suite. |
| - typeform is included in output. |
| ** Braille table improvements |

| - ~no-no-8dot.utb~: Norwegian 8-dot braille table |
| - ~no-no-8dot-fallback-6dot-g0.utb~: Norwegian 8-dot braille table |
| with uncontracted 6-dot fallback |
| - Changes to the Dutch tables |
| - Conforms better to the standard. |
| - ~nl-BE-g1.ctb~ renamed to ~nl-BE-g0.utb~ |
| - ~nl-NL-g1.ctb~ renamed to ~nl-NL-g0.utb~ |
| - Improvements to Danish tables: Added grade 2 with limited |
| contractions to 6 and 8 dots. Corrected contraction of many words. |

| - ~da-dk-g16.utb~ -> ~da-dk-g16.ctb~ |
| - ~da-dk-g18.utb~ -> ~da-dk-g18.ctb~ |
| - ~hyph_da_DK.dic~ -> ~hyph_brl_da_dk.dic~ |
| - Removed: ~da-dk-g28caps.cti~, ~da-dk-g28-patches.cti~ and |
| ~da-chardefs8.cti~ |
| ** Backwards incompatible changes |
| - The json based harness test suite has been removed as its |
| functionality has been superceded by the YAML tests. Please use |
| these from now on. |
| - A number of opcodes to handle emphasis have been renamed. |
| - The C API regarding the typeform parameter has changed. |
| |
| * Noteworthy changes in release 2.6.5 (2015-12-1) |
| This minor release introduces new tables (Mongolian and Norwegian 8 |
| dot) and new features to the tracing tool. But the most exiting news |
| about this release is probably the fact that 12 developers have |
| contributed to it, showing how widely used liblouis is and how |
| actively the development progresses. |
| |
| ** New features |
| - A DEF file is now generated automatically for the windows builds. |
| Thanks to Christian Egli |
| - lou_trace supports backtranslation now. Thanks to Bert Frees |
| |

| - Improvements to the Chinese braille table thanks to Coscell Kao. |
| - Massive improvements to Norwegian, thanks to Lars Bjørndal, Ammar |
| Usama and Jostein Austvik Jacobsen. They added a 8 dot table and |
| lots of test data. |
| - Improvements to Hungarian, thanks to Attila Hammer |
| |
| * Noteworthy changes in release 2.6.4 (2015-08-31) |
| This is a minor release in terms of features. But in terms of test |
| coverage and stability it is a vast improvement over previous versions |
| of Liblouis. The new YAML based test suite contains more than a |
| million of validated translations. Every change in Liblouis is tested |
| against this corpus ensuring the change doesn't break anything. |
| |
| ** New features |
| - YAML based harness tests. Harness tests can now be written in simple |
| YAML notation and they are integrated with the normal `make check` |
| command. They can be used for both ucs2 and ucs4 and no Python is |
| required. Thanks to Christian Egli. |
| |
| ** Bug fixes |
| - Use a separate gnulib instance for the library and the tools. Use |
| the strndup module to avoid build problems on windows. |
| - Fix a problem with the nocross opcode when used in combination with |
| the opcodes nocont and compbrl, thanks to Bue Vester-Andersen. |
| - Fix a problem with the decoding of the harness test files. Thanks to |
| Bert Frees. |
| - Fix numerous problems in the way braille indicators are handled. |
| There is now a safe version of the checkAttr function which makes |
| sure that no attributes are checked beyond the boundaries of the |
| currentInput. This fixes the random behavior with tests where the |
| emphasis extends to the end of the input string. Thanks to Christian |
| Egli. |
| |
| ** Other changes |
| - if found use texi2any to build the documentation, thanks to Martin |
| Michlmayr. |
| - Fix permissions of Korean tables, thanks to Peter Lundblad. |
| - Update the windows build instructions, thanks to Bue |
| Vester-Andersen. |
| |
| ** Braille table improvements |

| - Improvements to Hungarian 8 dot and Serbian grade 1, thanks to |
| Zvonimir Stanecic |
| |
| * Noteworthy changes in release 2.6.3 (2015-06-01) |
| Given the release number you might think this is only a minor release. |
| However looking at the number of developers who contributed to it and |
| the number of pull requests and issues that were solved this turns out |
| to be a very impressive and solid release. Most prominently we have a |
| new function to discover tables based on meta data in table headers. |
| Also makeinfo is no longer required to build liblouis. And lastly we |
| have numerous improvements in Braille tables such as Korean, |
| Vietnamese and UEB to name just a few. |
| |
| ** New features |
| - [beta] The new function lou_findTable can be used for table |
| discovery based on meta data in table headers. Thanks to Bert Frees. |
| - The Python API now has a new function to check tables aptly named |
| ~checkTable~. Thanks to Davy Kager. |
| |
| ** Bug fixes |
| - Fixed a problem in resolveTable when using a Java resolver, thanks |
| to Bert Frees |
| |
| ** Other changes |
| - The build dependency on makeinfo is now optional. If it is not |
| installed we simply do not build the documentation. |
| |
| ** Braille table improvements |
| - Improvements to Bengali, Devanagari, Kannada, Gujarati, Malayalam, |
| Telugu and Oriya, thanks to Sreeja Param |
| - Corrections and improvements made to en-GB tables thanks to Paul |
| Wood |
| - Vast restructuring to Korean tables. In 2006 the Institute for Korean |
| Braille modified some dots in Korean Braille. Specifically, some |
| punctuation dots are now based on English. To accommodate this change |
| and to retain the old tables, the Korean table set was revised as |
| follows: |
| - Added three files: ko-chars, the Korean characters dictionary, and |
| rules for g1 and g2. |
| - ko-g1 and ko-g2 are now interface files that includes needed |
| files. |
| - Added three files for Korean Braille 2006 revision along with a |
| test harness. |
| - New table for Polish 8 dot computer braille. Thanks to Karol Pecyna. |
| - New table for Vietnamese 6 dot. Thanks to Harri Pasanen. |
| - Corrections and improvements made to UEB tables thanks to Paul Wood |

| - Dash signs |
| - Math signs |
| - Accent modifiers |
| - Accented letters |
| |
| * Noteworthy changes in release 2.6.2 (2015-03-02) |
| This release, which was mostly pushed out the door by Bert and Mesar, |
| fixes a long standing emphasis bug, adds more functionality to the |
| harness test suite and improves, as usual, on Braille tables. Notably |
| there is a brand new finish table backed by Celia. |
| |
| ** New features |
| - Harness tests now can test for typeform differences. |
| |
| ** Bug fixes |
| - Fix for emphasis bug, thanks to Michael Gray |
| |

| - Corrections and additional test cases for Hungarian grade 1, thanks |
| to Hammer Attila. |
| - New 6-dot table for Finnish thanks to Jukka Eerikäinen from |
| Celia. The existing tables for Finnish were 8-dot, but there is an |
| official specification only for 6-dot braille in Finnish. |
| |
| * Noteworthy changes in release 2.6.1 (2014-12-01) |
| This release focuses on table and documentation improvements. The |
| documentation has been restructured to cater to people starting with |
| writing Braille tables. End users will see improvements to Braille for |
| Danish, Dutch, Hungarian, Irish and UK English. |
| |
| ** New features |
| *** New Braille tables |

| for reporting it and Michael Whapples for fixing the problem. |
| |
| ** Documentation updates |
| - The documentation has been restructured to be more beginner friendly |
| and a short introduction to translation table writing has been |
| added. Thanks to Joseph Lee and Christian Egli |
| |
| ** Other changes |
| - When compiling with mingw or cygwin resulting dll is liblouis.dll. |
| - runHarness.py: add new output format, compact output mode suitable |
| for grepping. |
| |
| ** Backwards incompatible changes |
| - Deleted ga.ctb now superseded by ga-g1.utb and ga.g2.ctb. |
| - Nl-Nl-g1.utb has been removed. It is superseded by nl-NL-g1.ctb. |
| - nl-be-g1.utb has been removed. It is superseded by nl-BE-g1.ctb. |
| |
| * Noteworthy changes in release 2.6.0 (2014-09-01) |
| This is the first release by the new maintainer team. A lot of work by |
| people from across the community contributed to this release. There |
| are massive additions and updates to the Braille tables (e.g. |
| Afrikaans, Hebrew, many Indian languages, Korean) and also changes to |
| the C API to enable call backs for error messages and warnings. |
| |
| ** New features |
| *** New Braille tables |
| - Tables for Afrikaans, Cherokee, Hawaiian, Maori, Sotho and Tswana |
| were donated by Greg Kearney. Afrikaans, Cherokee, Maori and Hawaiian |
| all are grade 1 tables and with the exception of Cherokee were |
| derived from World Braille Usage 2013. The Cherokee was taken from |
| the specification published at www.cbtbc.org/cherokee/. |
| *** Logging callback |
| There is now a callback system in place to get error messages and |
| warnings. This can be used from programs that use liblouis to log |
| warnings for example. |
| |
| ** Bug fixes |
| - fix back translation problems when word gets split in unusual places |
| causing back translation of whole words for example K5 back |
| translates to Knowledgeen, M>k back translates to Moreark, and M5 |
| back translates to Moren. This caused over 8400 extra back |
| translation errors in en-us-g2 and 5000 in en-ueb-g2. Thanks to Ken |

| etc. |
| - Updated braille codes according to prescribed braille codes for |
| each Unicode character by the Braille Council of India for all |
| Indian languages. |
| - defined rules for dealing with Nukhta character in Hindi table |
| - defined rule to insert dot-1 between consonant followed by full |
| vowel character in all Indian Languages |
| - defined rules for shifting of halant character before the |
| consonant. This character is placed after the consonant in normal |
| typing but need to be before the consonant in braille. This rule |
| is applicable for all Indian languages. |

| all Indian Languages for which there are specific codes in |
| Braille. |
| - New Hebrew table that is based on the new unified Hebrew Braille |
| code standard that was put together on January 2014 after a |
| conference with all of the specialists in this field in Israel. It |
| includes improved representation of Hebrew letters, special letters |
| that are called Nikud, and punctuation symbols. The old Braille |

| new tables the long awaited table for UEB is finally here. |
| |
| ** New features |
| *** New tool to trace rule application |
| There is a new tool (lou_trace) which helps to trace which rules |
| have been used to perform a Braille translation. This is helpful |
| for writing Braille tables. See the documentation for more |
| information. |
| *** New Braille tables |
| - Inuktitut grade 1, thanks to Greg Kearney. |
| - UEB grade 1 and 2, thanks to Joseph Lee. These tables replace |
| the old UEB tables (UEBC-g1.utb and UEBC-g2.ctb). |
| - Korean table thanks to Joseph Lee |
| |

| output characters. |
| |
| * Noteworthy changes in release 2.5.0 (2012-9-10) |
| |
| This release contains a tremendous amount of work many developers. |
| Many long standing bugs have been fixed. The tables can finally be in |
| UTF-8. A grand table cleanup removed duplication from the tables. |
| There are now two extensive test frameworks for table writers. A |
| number of new tables have been contributed on top of the usual |
| assortment of table improvements. Thanks to all of this liblouis has |
| already seen quite a bit of uptake in a number of places, notably the |
| new DAISY pipeline will ship with this release of liblouis. |
| |
| NOTE: If you have private tables you might want to migrate them to |
| utf-8. To do this just use iconv as follows: |
| |
| $ iconv -f latin-1 -t utf-8 <input >output |
| |
| ** New features |
| *** New Braille tables |
| - Estonian grade 0, thanks to Jürgen Dengo. |

| *** Add a doctest infrastructure |
| These tests are based on the Python doctest framework and are only |
| run if there is a Python interpreter on the system |
| *** Add a test harness |
| This test infrastructure allows the user to do table tests in a |
| simple and concise syntax. These tests are based on the Python |
| nose testing framework and are only run if either Python 2.x or |
| 3.x with the related nose python module is installed on the |
| system. See the documentation for more information. Thanks to |
| Mesar Hameed. |
| *** Add a test harness generator |
| A harness generator that uses simple text files with a little |
| formatting to help to generate the json harness files. The purpose |
| of this tool is to make it much easier and faster to add checks |
| for a given table. You are expected to read the generated harness |
| file and make necessary changes, the tool only helps you to get |
| the tests into the harness format, not check their validity. |
| *** Support for Python 3 in the Python bindings |
| The Python bindings now work for both Python 2 and Python 3. |
| Thanks to Michael Whapples. |
| |
| ** Improved C-based test framework |
| - Improved the test framework to be able to test translations |
| involving Unicode. |

| bindings and a number of buffer overruns in the C library). |
| Thanks Milan Zamazal <pdm@brailcom.org> for reporting this. |
| - Fix a bug in the $a. matcher in the multipass rules where only 32 |
| chars were matched. It now matches 0xffff chars. |
| - Fix a bug reported by James Teh related to pass1Only |
| |
| ** Braille Table Improvements |
| - all table files have consistent encoding, UTF-8. |
| - The grand table cleanup: Reorganize the tables to remove |
| duplication. Move common parts such as Latin letter, eight and |
| six dot digit definitions to separate files which are then |
| included. This should ease table maintenance. Thanks to Mesar Hameed. |
