| |
| The liblouis developer team is proud to announce the liblouis release |
| 3.38.0. 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 highlighted by a new Norwegian grade 3 contraction |
| table, the result of Lars Bjørndal's work implementing the revised |
| Braille Authority rules. The Swedish tables have been thoroughly renewed |
| and now also cover Sami and Elfdalian. Malayalam has been updated to |
| comply with the new Bharati Braille 2026 rules. Several security |
| vulnerabilities were fixed, and the documentation was improved. |
| |
| 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]_. |
| |
| Bug fixes |
| --------- |
| |
| - Fix several memory safety issues: |
| |
| - a heap-buffer-overflow in ``back_passDoAction`` thanks to Justin |
| Stitt; |
| - a null pointer dereference in ``pattern_compile_expression``, a |
| buffer overflow in ``_lou_logWidecharBuf``, null pointer |
| dereferences in ``_lou_compileTranslationRule`` and |
| ``_lou_compileDisplayRule``, a segfault in ``lou_compileString``, |
| and missing length validation in ``_lou_backTranslate``, all |
| thanks to FuzzAnything. |
| |
