| The liblouis developer team is proud to announce the liblouis release |
| 3.33.0. 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 combines braille improvements with security enhancements. |
| We have new tables for Coptic braille, Cuneiform transliteration and for |
| Portuguese 6-dot computer braille. There are improvements to Dutch, |
| Hungarian, the International Phonetic Alphabet, Norwegian and UEB. On |
| the security side a lot of people have reported and fixed buffer |
| overflows and other memory issues. |
| |
| 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]_. |

| Frees |

| - Improvements to the UEB table thanks to James Bowden. In particular |
| the handling of words containing "somer", e.g. "Somerville" was |
| fixed. |
| - Hungarian improvements (added more exceptions) thanks to Attila |
| Hammer. |
| - Add a new 6-dot table for literary Coptic braille, thanks to Eric |
| Harvey. |
| - Added some missing symbols (including space) to the table for the |
| International Phonetic Alphabet, thanks to James Bowden. |
| - Add a table for Portuguese 6-dot computer braille, thanks to Tiago |
| M. Casal and Iván Argote-Pérez. The table is based on the official |
| documentation in Portuguese [4]_. |
| - Add a new table for Cuneiform transliteration. It differs from the |
| existing table ``cuneiform-transliterated.utb`` in that it does not |
| adopt UEB dot patterns for the various diacritic marks. Instead it |
| uses bespoke diacritics inspired by some IPA symbols. Thanks to Eric |
| Harvey. |
