| liblouis 3.16.0 has been released |
| |
| The liblouis developer team is proud to announce the liblouis release |
| 3.16.0. The release is available for download at: |
| |
| https://github.com/liblouis/liblouis/releases |
| |
| Introduction |
| ============ |
| |
| Liblouis is an open-source braille translator and back-translator. It |
| features support for computer, literary and math braille, supports |
| contracted and uncontracted translation for many, many languages [1]_. |
| It plays an important role in an open source accessibility stack and is |
| used by screenreaders such as NVDA, Orca and JAWS. A companion project |
| liblouisutdml [2]_ deals with formatting of braille. |
| |
| Noteworthy changes in this release |
| ================================== |
| |
| 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 the list of closed |
| issues [3]_. |
| |
| New features |
| ------------ |
| |
| - A new opcode ``noemphchars`` was added. This gives you more control |
| over the placement and scope of various emphasis indicators. Thanks |
| to Bert Frees. |
| |
| Bug fixes |
| --------- |
| |
| - Fix an endless loop when using ``compbrlAtCursor`` thanks to Bert |
| Frees |

| |
| - Improvements to US EBAE conformance with BANA emphasis guidelines |
| thanks to Benetech.org |
| - Fixed a problem with apostrophe in Malayalam thanks to Jake Kyle |
| - Improvements to contraction use in UEB thanks to James Bowden. In |
| particular the checkmark (U+2713) is added, the emdash (U+2014) is |
| fixed, the right single quote used as apostrophe between letters is |
| fixed and finally some more accented letters have been added. |
| - Improvements to Urdu Braille and Malayalam thanks to Jake Kyle |
| - Add characters for Bashkir and Uzbek languages to the Russian |
| computer braille table. Thanks to Andrey Yakuboy. |

| punctuation. |
| |
| - Improved translation of ligatures in UEB thanks to Bert Frees. |
| - Multiple improvements to the Russian literary braille thanks to |
| Andrey Yakuboy and Bert Frees: |
| |
| - Many new symbols (punctuation, bullets, math symbols, etc) have |
| been added. |
| - Punctuation after digits and fractions is now marked with dot 6 to |
| exclude ambiguities. |
| - Bugs, such as passing dot 7 in braille Unicode characters, have |
| been fixed. |
| - Added the new table with indicating of Cyrillic capital letters. |
| This recommended for braille display users. |
| - Removed ``ru-ru-g1.utb`` which was used in many screen-readers as |
| the only Russian literary braille table. Now it's necessary to use |
| ``ru-litbrl.ctb`` and ``ru-litbrl-detailed.utb``. |
| - Other minor rules according to actual Russian braille rules. |
| |
| Other changes |
