liblouis 3.4.0 has been released

The liblouis developer team is proud to announce the liblouis release
3.4.0. 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.

Changes in this release
=======================

This release brings together a lot of work by lots of different
people. Probably the most prominent fix is the work on output
positions by Bue and Bert. NVDA should benefit from this. Then there
are new and massively improved tables like the Lithuanian 6-dot table
by Rimas or the improved back-translation for French by Michel and
André-Abush to name just a few. There are too many contributors to
name them here, thanks to them all.

New features
~~~~~~~~~~~~
- Add support for `inputPos' and `outputPos' checking in
  `lou_checkyaml' thanks to Bue Vester-Andersen. See the manual for
  details and examples.


Bug fixes
~~~~~~~~~
- output positions (`outputPos') are now calculated based on input
  positions (`inputPos') thanks to Bert Frees. This avoids a whole
  class of bugs that previously plagued the output positions. This fix
  also obviates the need for the `pass1Only' flag. See below for the
  deprecation notice.

- Addition of Nemeth and Kangxi radical characters and other
  improvements to Chinese braille (`zh-tw.ctb') thanks to Bo-Cheng

  Barajas and Simon Aittamaa.
- Fixed a lowercase ó in Spanish first reported for NVDA thanks to
  Sukil Etxenike.

  thanks to Lars Bjørndal

- Addition of more characters to the French tables thanks to Samuel
  Thibault
