Liblouis Release 3.18.0

07 Jun 2021 - Liblouis

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.

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.
  • Major update to the grade 2 Afrikaans table. It now implements the new Afrikaans rules adopted and implemented recently by the South African Braille Authority. The rule changes simplify and rationalize the rules, especially those based on pronunciation. 571 of the list of 25912 test words were impacted by the changes and all have been corrected.
