The liblouis developer team is proud to announce the liblouis release
3.18.0. 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 brings support for many new languages: There is support for
six new languages from South Africa, Northern Kurdish, Kazakh, Tatar,
Yakut, Bulgarian literary braille and finally Khmer, Burmese and
Vietnamese. Aside from that there are also major improvements to
Afrikaans, Russian literary braille, Uzbek and Hebrew Computer Braille.
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
---------
- Don't silently ignore the last line of a table when it doesn't end
with a new line character. Thanks to Bert Frees.
Braille table improvements
--------------------------
- New contracted braille table for the isiXhosa and isiZulu languages
created by Christo de Klerk and Laurent Cadet de Fontenay at the
request and under the auspices of the South African Braille
Authority.
- New contracted braille table for the Sesotho, Setswana and Sepedi
languages created by Christo de Klerk at the request and under the
auspices of the South African Braille Authority.
- New braille table for Northern Kurdish thanks to Imam Kahraman.
- Fix a problem with ']' in Finnish 8 dot braille thanks to Christian
Egli. The real problem was an unintended continuation line.

new Afrikaans rules adopted and implemented recently by the South

the rules, especially those based on pronunciation. 571 of the list

corrected.

Yakuboy and Bert Frees:
