 * Noteworthy changes in release 3.24.0 (2022-12-05)
 This release contains major updates to Hungarian, UEB, and Chinese
 bopomofo braille. Danish has been completely reworked and there is now
 support for the Danish braille standard 2022. There are also some new
 tables so that liblouis can now generate Georgian computer braille,
 Swahili (Kenya) and Chichewa (Malawi). Aside from that there is the
 usual assortment of code cleanups and bug fixes.

 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/34?closed=1][the list of closed
 issues]].

 ** Braille table improvements
 - New grade 1, 1.2, 1.3, 1.4, 1.5 and 2 tables for Swahili (Kenya) and
   grade 1 table for Chichewa (Malawi) thanks to Jake Kyle, Dipendra
   Manocha and Martin Kieti.
 - Improvements to Hungarian thanks to Attila Hammer.
 - Update braille patterns of some Chinese characters and phrases in
   the Chinese bopomofo braille table thanks to Bo-Cheng Jhan.
 - Add experimental Georgian computer braille table thanks to Harris
   Mowbray and Mariam Mikiashvili.
 - Updated the Danish tables to the new 2022 Danish braille standard
   thanks to Bue Vester-Andersen.
   - Limited contraction level (grade 2l or 1.5) is no longer part of
     the Danish braille standard 2022.
   - There is no longer any need for "literary" tables. In Danish
     braille, capital letters are now always indicated, and steps have
     been taken in the standard to ensure better back-translation.
   - As requested by The Danish Braille Committee, the tables for the
     1993 standard will be kept as an option for at least a year. All
     the 1993 tables have been renamed to include "_1993" in the
     filename, so the new tables will be used as default.
 - Improvements to UEB thanks to James Bowden.
   - Add new sign for German sharp S (ICEB July 2022)
   - Fix a couple of acronyms which require grade 1 indicator (LLB, LLP)
   - Fix placement of numeral sign in letters comma digits
   - Review rules for "under" and "there" contractions

 * Noteworthy changes in release 3.23.0 (2022-09-05)
 This release contains significant updates to many existing braille
 tables (Chinese bopomofo, Hungarian, Japanese, Russian, Swedish, UEB
 grade 2 Ukrainian). On top of that it also contains new tables for
 /Chinese Common Braille Scheme/, Kinyarwanda and Luganda thanks to
 Cary-Rowen and Jake Kyle. Behind the scenes Samuel Thibault has been
 working tirelessly to fix memory related bugs.

 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/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

   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.
 - Prevent an invalid memory writes in ~compileRule~. Thanks to Han
   Zheng for reporting it and to Christian Egli for fixing it.

   thanks to Mario Arias.
 - Major improvements to the Hungarian braille tables thanks to Attila
   Hammer.
 - Make Punjabi table to behave the same as Duxbury in forward
   translation and more reliably than Duxbury in back
   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.

 * 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.
 - Improvements to Polish literary braille table thanks to Łukasz
   Golonka.
   - use correct representation of indexes for squared, cubed etc.
   - use correct representation for fractions
   - change symbol used for underscore from dots 46 to 6
   - add U+2212 minus symbol (also to computer braille table)
 - Updates to the Chinese bopomofo braille table thanks to Bo-Cheng
   Jhan.
   - Complete translation of CJK Radicals Supplement
   - Change the default braille pattern of '蛤' to ⠗⠜⠂
   - Correct the default braille pattern of many Chinese characters
   - Add various Chinese phrases involving exceptions of braille
     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.

 * 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.

 * Noteworthy changes in release 3.17.0 (2021-03-08)
 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
 provided a new table for Belarusian uncontracted and computer braille.
 Aside from that there are numerous improvements in Braille tables such
 as French, Polish and Urdu. The documentation has been improved as has
 the table meta marking the tables whether they are geared towards
 forward or backwards translation. 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/27?closed=1][the list of closed
 issues]].

 * 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.

 For a detailed list of all the changes refer to [[https://github.com/liblouis/liblouis/milestone/26?closed=1][the list of closed
 issues]].

 *** Removed
 - 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.

 ** Invisible changes
 ** New, renamed or removed tables

 * 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
 issues]].

 ** 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

 ** Invisible changes
    - Internally separate more clearly the display and translation
      phases.

 * 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

 * 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

 * 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]].

   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

 - 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.

 ** Backwards incompatible changes
 - None

 ** New, renamed or removed tables
 *** New
 - cs-comp8.utb
 *** Renamed

 * 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

   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

   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.

 * 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

 - 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]].

 ** New features

   - 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.

 ** 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

 - 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.

   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.

   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.

 * 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
   Perry.
 - Fixed bug to prevent removal of \xffff between largesign rules. This
   solves a Liblouisutdml bug where \xffff is used as a segment
   delimiter.
 - Fixed a bug in back translation, when a letsign was encountered, the
   letsign was being applied beyond the element it applied to.
 - Fix memory leaks in the default table resolver introduced in the
   previous release.
 - Fixes to the build system by Simon Aittamaa

 ** Braille table improvements
 - Major improvements to Indian tables thanks to the Indian National
   Institute for Visually Handicapped, in particular Dipendra Manocha,
   Mesar Hameed, Dinesh Kaushall and Sreeja Parameswaran:
   - Corrected opcodes for letters, punctuation marks, digits, signs
     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.
   - defined rules for two conjunct characters "ksha and gya" used in
     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
   standard is not relevant any more. Thanks to Adi Kushnir.
 - UEB table fixes: Fix ity contraction, fixed the missing end word
   contraction ;n ;d sign 46. thanks to Ken Perry.
 - Fix for Norwegian where letsign is affecting some extra characters
   thanks to Lars Bjørndal
 - Much improved hyphenation for Norwegian thanks to Lars Bjørndal
 - Korean Grade 2 now includes support for reading English text using
   grade 2.

      John Boyer.
    - Fixed several problems with back-translation. A slash within a
      number and strings such as 5-inch-diameter and 25-year-old-man
      should now back-translate correctly. Thanks to John Boyer.
    - Fixed a problem with syllable opcode. Thanks to John Boyer.
    - Fix warnings with gcc 4.8.2. Thanks to Peter Lundblad.
    - When a table is specified with an absolute or relative path, the
      "includes" in that table will now work as expected, meaning files
      in the same directory will be found.

       letters, thanks to Aaron Cannon.

 *** runHarness.py:
     Accept filename globs on the commandline to run specific harness files.
     In tests/harness, one can do make <filename> or make runall
     Removed from make check because these checks are checking the validity
     of our tables, rather than validity of the code.

 ** Braille Table Improvements
    - da-dk-g2.ctb, mostly rewritten to use nocross and hyphenation
      table.
    - Most tables: removed the default collapse whitespace statements,
      if you need to compress whitespace, consider adding compress.ctb
      to the list of tables when processing.
    - Corrections to Unified English Braille Code (Grade 1 and 2),
      thanks to Joseph Lee
    - Corrections to apostrophes in the Computer Spanish 8 dots Braille
      table (Es-Es-G0.utb). Thanks to Juan C. Buno.
    - Corrections for double angle quotation marks and emphasis marks
      in the Norwegian Grade 0 Braille Table. Thanks to Knut Arne
      Bjørndal.
    - Fixes for a minor problem regarding the noletsign in Norwegian
      contracted braille. Thanks to Lars Bjørndal.
    - Corrections to the Italian table thanks to Igor B. Poretsky.
    - Corrections to the Hungarian grade 1 table thanks to Hammer
      Attila
    - Corrections to English, U.S. Grade 2 (ABAE) table. Thanks to Ken
      Perry for reporting the bug and John J. Boyer for fixing it.
    - Further reorganization of the tables to remove duplication. Move
      litdigit opcode common parts and include where needed.
    - Removed obsolete en-us-g1.utb, which has been replaced by
      en-us-g1.ctb.
    - Added dictionary harness tests for: en-ueb-g2.ctb, en-us-g2.ctb.
    - Corrections to Nemeth character definitions thanks to Neil
      Soiffer.
    - Corrections to the Esperanto table thanks to Aaron Cannon.

 ** Bug Fixes
    - Cursor position calculation is now based on the same code that
      calculates inpos and outpos. This probably solves a number of
      bugs.
    - Fix nocross opcode processing.
    - Fix several buffer over/under runs in
      lou_translateString.c:hyphenate.
    - Fix the '=' problem, i.e. fix inputPositions calculation for the
      case where the equals sign is used as the dots operand. Thanks to
      Bert Frees
    - Fix a bug when resizing a table. Previously not all references to
      this table were updated.

 ** Backwards incompatible changes
    - The feature that allowed a mapping between language code and
      Braille table was removed as it contained a out-of-bounds access
      bug, was never documented and probably never used. Thanks to
      Peter Nilsson Lundblad and Jeremy Roman for analyzing this
      problem and providing a patch.

 * Noteworthy changes in release 2.5.2 (2012-12-18)

 While initially planned as mainly a bug fix release this release
 contains some notable new features: There is a new tool to trace which
 rules have been used to perform a translation. Also along with other
 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

 ** Braille Table Improvements
    - da-dk-g2.ctb, fixes for transposed â, å, æ, ä, ø  and ö,
      corrected/improved harness tests.
    - Corrections for en-GB-g2.ctb thanks to Paul Wood
    - Corrections to the Hungarian grade 1 table thanks to Hammer
      Attila

 ** Bug Fixes
    - Update gnulib
    - Fix a bug in the correct opcode which causes sometimes random
      results when translating. Thanks to Bert Frees.
    - Fixes for compiler warnings.
    - Fix some Valgrind warnings about invalid reads

 * Noteworthy changes in release 2.5.1 (2012-9-24)

 ** Braille Table Improvements
 - Fix encoding problem in italian table and added more character
   definitions. Thanks to Simone Dal Maso <simone.dalmaso@juvox.it>.
 - Rename it-it-g1.utb to it-it-comp6.utb and it-it-g1.utb2 to
   it-it-comp8.utb.

 ** Bug fixes
 - Fix outputPos and inlen where an input character generates multiple
   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.
     - Portuguese 8 dot Computer braille, Thanks to Rui Fontes
 *** UTF-8 support in tables
     Braille tables can now contain UTF-8 in the opcode arguments.
 *** Improvements to the python bindings
     All constants defined in liblouis.h are now exposed in the bindings.
 *** 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.
    - Added numerous tests, e.g. for lowercase and Unicode, for the
      input position, for repeated, etc.

 ** Improved the documentation
    - Document the test harness (json format, fields, flags).
    - Document the use of Valgrind to find memory leaks
    - Improve the documentation on the display opcode

 ** Bug fixes
    - lou_allround and lou_translate now properly handle Unicode
      characters
    - Fix some issues reported by Valgrind
    - Fix inputPos for situation where context and multipass opcodes
      are involved
    - Fixed a number of bugs with the letter, uppercase and lowercase
      opcodes when dealing with Unicode
    - Fixed a couple of bugs with hyphenation (documentation, Python
      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.
    - Fixes to de-de-comp8.ctb thanks to Aliminator83@gmail.com
    - hu1.ctb renamed to hu-hu-g1.ctb
    - hu.ctb renamed to hu-hu-comp8.ctb
