| 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][2] deals with formatting of braille. |
| |
| Changes in this release |
| ======================= |
| |
| This release contains the usual assortment of braille table |
| improvements, cleanups and bug fixes. The most prominent change is the |
| refactoring of the call APIs by Bert Frees that makes the code much |
| more manageable and solid and will help us in the future to evolve the |
| library. |
| |
| For a detailed list of all the changes refer to the list of closed |
| issues[3]. |
| |
| New features |
| ~~~~~~~~~~~~ |
| |
| - Add metadata fields `name' and `display-name' to tables thanks to |
| Bert Frees. The `name' contains a description of the table in the |
| native language. `display-name' contains an English description. |
| - YAML test enhancements |
| - You can now test both forward and backwards translation with in |
| the same YAML file and for the same set of tables tests thanks to |
| Bue Vester-Andersen. See the documentation for the |
| `bothDirections' testmode. |
| - Add `maxOutputLength' option in YAML tests. |
| |
| Bug fixes |
| ~~~~~~~~~ |
| |
| - Fix a bunch of buffer overflow errors in table parsing thanks to |
| Samuel Thibault and Christian Egli (CVE-2018-11410 and |
| CVE-2018-11440). |
| - Fix input-output mapping of context rules thanks to Bert Frees. |
| - Fix back tracking with all caps words thanks to Bert Frees. |
| - Fix context rules with lookback thanks to Bert Frees. |
| - Fix a memory leak in default table resolver thanks to Timothy Lee. |
| - Fix an array out of bounds error which caused a crash on i386 thanks |
| to Samuel Thibault. |
| - Fix numerous stack-based buffer overflow in table parsing thanks |

| |
| Braille table improvements |
| ~~~~~~~~~~~~~~~~~~~~~~~~~~ |
| |
| - Fix some forward- and back-translation errors in Unified French |
| Grade 2 thanks to André-Abush Clause. |
| - Updates to the Simplified-Chinese Braille Translation Table thanks |
| to Roshanson |
| - Added many polygraphs to distinguish different meanings of a word |
| - Letter identifiers have been modified. In China's school for the |
| blind, when many visually impaired students learn, the lowercase |
| letters often do not have to mark the identifiers deliberately. So |
| in this version, we this item has been deleted. |
| - Fixed a bug in the braille code that revises the space and 0 |
| - Updates to Bopomofo-based Chinese Braille Table thanks to Bo-Cheng |
| Jhan |
| - Redefine some Chinese words and phrases |
| - Add various Nemeth symbols such as arrows and parenthesis |
| - Complete the support of CJK Compatibility block |
| - Fix the support of various parentheses, brackets, and braces |
| - Minor fixes (kana rules, punctuation marks, Greek alphabets) |
| - New 8 dot computer braille table for Czech thanks to Jan Hegr. |
| - Fixes to Czech 6 dot table thanks to Jan Hegr |
| - Fixed curly brackets representation |
| - Fixed number sign representation |
| - Added copyright sign |
| - Minor fixes to Hebrew thanks to Erez Kugler. |
| |
| Other changes |
| ~~~~~~~~~~~~~ |
| |
| - Refactoring thanks to Bert Frees |
| - Simplify the emphasis class handling by combining all related vars |
| in a struct `EmphasisClass' |
| - Simplify input/output buffer handling |
| - Combine `emphasisBuffer' and `transnoteBuffer' |
| - Group match related vars in a struct `PassRuleMatch' |
| - Remove dead code |
| - Fixed many warnings thanks to Christian Egli |
| |
| Deprecation notice |
| ~~~~~~~~~~~~~~~~~~ |
| |
| - The `mode' parameter in `lou_dotsToChar' never had any effect and is |
| now deprecated. |
| - In 2012 a new way to specify the test and action part in context and |
| multipass opcodes was introduced. It was never documented and has no |
| known usage in the wild. However it opens up the attack surface to |
| the table parsing code. Therefore it is deprecated and will be |
| removed in the next release. |
