| |
| * Noteworthy changes in release 3.4.0 (2017-12-04) |
| 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. |
| |
| For a detailed list of all the changes refer to [[https://github.com/liblouis/liblouis/milestone/14?closed=1][the list of closed |
| issues]]. |
| |
| ** 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. |

| translations. For a detailed list of all the changes refer to [[https://github.com/liblouis/liblouis/milestone/13?closed=1][the list |
| of closed issues]]. |
| |
| ** New features |
| *** maketable tool |
| A new tool ~lou_maketable~ enables the creation of tables based on a |
| corpus of known good Braille translations. This has huge potential to |
| simplify table maintenance for tables that have so far been dominated |
| by large exception lists. Thanks to Bert Frees. |

| |
| * Noteworthy changes in release 3.1.0 (2017-03-06) |
| An influx of new contributors have made sure that liblouis continues |
| to improve. Back translation has seen major improvements, there are |
| some additional modes to help screen readers, for many tables meta |
| data has been added, the Python bindings are more robust, Windows |
| support has been improved, the YAML test suite has been generalized |
| and as usual new and improved braille tables have been included. On |
| the licensing front we managed to get almost all tables re-licensed to |
| LGPLv2.1+. |
| |
| ** New features |
| *** Meta data |
| Most of the translation tables now contain meta data. This makes them |
| discoverable. Programs can use the lou_findTable function to find a |
| table based on a query. |
| |
| *** noUndefinedDots mode |
| Add a noUndefinedDots mode to disable the output of dot numbers when |
| back-translating undefined patterns. Thanks to James Teh. |
| |
| When back translating input from a braille keyboard cell by cell, it is |
| desirable to output characters as soon as they are produced. |
| Similarly, when back translating contracted braille, it is desirable to |
| provide a "guess" to the user of the characters they typed. To achieve |
| this, liblouis needs to have the ability to produce no text when |
| indicators (which don't produce a character by themselves) are not |
| followed by another cell. This works already for indicators liblouis |
| knows about such as capital sign, number sign, etc., but it does not |
| work for indicators which are not (and cannot be) specifically defined |
| as indicators. For example, in UEB, dots 4 5 6 alone produces the text |
| "\456/". Setting the noUndefinedDots mode suppresses this dot number |
| output. |
| |
| *** partialTrans mode |
| Add a partialTrans mode to specify that back-translation input should |
| be treated as an incomplete word. Thanks to James Teh. |
| |
| If this mode is set, rules that apply only for complete words or at |
| the end of a word will not take effect. This is intended to be used |
| when translating input typed on a braille keyboard to provide a rough |
| idea to the user of the characters they are typing before the word is |
| complete. |
| |
| *** YAML test framework |
| The YAML framework has been extended and is much more useful now. You |
| can test multiple tables within one YAML file, you can define test |
| tables directly inline and you can test multiple tables using the same |
| test data. Refer to the documentation for the details. |
| |
| If really not wanted the YAML tests can be disabled by specifying |
| ~configure --without-yaml~. |
| |
| ** Bug fixes |
| - Fixes implicit declaration of 'pattern_check' thanks to Reiner Dolp |
| - Fix a stackoverflow crash on applications with smaller stack size. |
| Thanks to Victor Montalvão. |
| - Fix the \v escape sequence. Thanks to Davy Kager. |
| - The Python bindings now give a helpful error if liblouis has been |
| compiled with a different character size than Python. Thanks to Matt |
| Wenn. |
| - Massive bug fixes in multipass rules. Dave Mielke has done a |
| tremendous job improving the multipass machinery also in the |
| context of back-translation. Where needed nofor/noback has been |
| added to the multipass rules. |
| |
| ** Other changes |
| - Improvements to the Emacs mode for editing liblouis tables thanks to |
| Christian Egli |
| - Documenting lou_charSize thanks to Reiner Dolp |
| - Support for relative table paths in the tests. This will make sure |
| you always know which table a test actually uses. |
| - Infrastructure to build windows binaries in a Docker container, |
| thanks to Bert Frees |
| |
| ** Braille table improvements |
| - UEB improvements, thanks to Mike Gray |
| - Fixed apostrophe and back translation |
| - Added rules for Unicode apostrophe handling |
| - Improvements to UEB and Nemeth math |
| - Complete overhaul of Lithuanian 8-dots table, thanks to Rimas |
| Kudelis |
| - New Urdu 6 Dot Grade 1 and 2 Braille tables thanks to Jake Kyle |
| - Improvements to Italian 8 dots computer braille, thanks to Simone |
| Dal Maso. |
| - New table ~unicode-braille.utb~ that helps to back translate braille |
| input to Unicode braille output, thanks to Leonard de Ruijter. |
| - Improvements to the Chinese braille table thanks to Coscell Kao. |
| - New Turkish braille table for grade 1 that should replace the |
| old ~tr.ctb~ table, thanks to Arend Arends. |
| - New Persian grade 1 table and 8-dots computer table thanks to |
| Mohammadreza Rashad. |
| - New table for the International Phonetic Alphabet thanks to Ludovic |
| Oger |
| - Fixes for the French 6 and 8 dots tables thanks to Michel Such. Some |
| errors have been fixed and many Unicode characters have been added. |
| - Add an extended 8-dot computer braille table for U.S. English thanks |
| to Davy Kager. The table is tailored for use on Windows (CP-1252) |
| and uses dot patterns from Windows screen readers, but should be |
| useful on other platforms too. |
| - New Greek table that is better than the existing Greek Grade 1 |
| Braille Table (gr-gr-g1.utb) thanks to Dave Mielke. |
| - Improved number back-translations on fr-fr-g1 and vi-g1 tables |
| thanks to Victor Montalvao. |
| - New Chinese Braille table for use in the mainland of China thanks to |
| Kaifang Bao of RejoinTech. |
| - The Black Circle character is commonly used for displaying password |
| characters. The absence of its definition leads to users not being |
| able to know how many characters were typed in such fields. This has |
| been improved for many tables thanks to Victor Montalvao. |
| |
| ** License changes |
| - DocArch has agreed to re-license their tables, so we have 8 more |
| tables under the LGPLv2.1+. |
| |
| ** Backwards incompatible changes |
| - The naming in the YAML test framework has changed slightly from |
| `tables:` to `table:`. |
| |
| * Noteworthy changes in release 3.0.0 (2016-07-14) |
| This is the biggest release of liblouis in years. The major news are |
| that we now have proper support for UEB and secondly that liblouis is |
| now licensed under [[https://www.gnu.org/licenses/old-licenses/lgpl-2.1.html][LGPLv2.1+]]. |
| |
| In order to support UEB the internals of liblouis have seen a major |
| rewrite. New Opcodes have been added to support the requirements for |
| proper UEB for example for emphasis handling or to handle proper |
| translation of numbers. Changes to the opcodes are described in the |
| documentation. Some of these changes are not backwards compatible. All |
| tables that come with liblouis have been migrated. If you have private |
| tables look at the section on upgrading from previous versions in the |
| [[https://github.com/liblouis/liblouis/wiki/Emphasis-Opcodes#upgrade-from-previous-versions][wiki]]. |
| |
| This release also changes the C API. External applications will have |
| to adapt the way they call liblouis. In particular the typeform |
| parameter has changed. |
| |
| The license of the library and most of the tables has been changed to |
| LGPLv2.1. For a detailed list which tables are still in the process of |
| migrating the license refer to the [[https://github.com/liblouis/liblouis/wiki/Licensing-of-liblouis-tables][wiki page about the license change]]. |
| |

| - support translation of numbers according to the rules of UEB. |
| - Capitalization is now handled just like emphasis. |
| - support for numeric mode |
| - UTF-8 support for all tools thanks to Christian Egli. |
| - The YAML tests now allow for an optional test description. See the |
| documentation for more details. |
| - Add ~lou_checkTable~ and ~lou_getTypeformForEmphClass~ to the C API |
| and to the Python bindings |
| ** Bug fixes |
| - Stop buffer overrun in ~lou_getProgramPath~, and also free memory |
| after usage. Thanks to Michael Curran. |
| ** Other changes |
| - The license of the library and most of the tables has been changed |
| to [[https://www.gnu.org/licenses/old-licenses/lgpl-2.1.html][LGPLv2.1+]]. |
| - Improvements to the test suite: |
| - Output is printed to ~stderr~. This helps with locating errors when |
| testing with the YAML test suite. |
| - typeform is included in output. |

| - ~no-no-8dot.utb~: Norwegian 8-dot braille table |
| - ~no-no-8dot-fallback-6dot-g0.utb~: Norwegian 8-dot braille table |
| with uncontracted 6-dot fallback |
| - Changes to the Dutch tables |
| - Conforms better to the standard. |
| - ~nl-BE-g1.ctb~ renamed to ~nl-BE-g0.utb~ |
| - ~nl-NL-g1.ctb~ renamed to ~nl-NL-g0.utb~ |
| - Improvements to Danish tables: Added grade 2 with limited |
| contractions to 6 and 8 dots. Corrected contraction of many words. |

| - ~hyph_da_DK.dic~ -> ~hyph_brl_da_dk.dic~ |
| - Removed: ~da-dk-g28caps.cti~, ~da-dk-g28-patches.cti~ and |
| ~da-chardefs8.cti~ |
| ** Backwards incompatible changes |
| - The json based harness test suite has been removed as its |
| functionality has been superceded by the YAML tests. Please use |
| these from now on. |
| - A number of opcodes to handle emphasis have been renamed. |
| - The C API regarding the typeform parameter has changed. |
| |
| * Noteworthy changes in release 2.6.5 (2015-12-1) |
| This minor release introduces new tables (Mongolian and Norwegian 8 |
| dot) and new features to the tracing tool. But the most exiting news |
| about this release is probably the fact that 12 developers have |
| contributed to it, showing how widely used liblouis is and how |
| actively the development progresses. |
| |
| ** New features |
| - A DEF file is now generated automatically for the windows builds. |
| Thanks to Christian Egli |

| lots of test data. |
| - Improvements to Hungarian, thanks to Attila Hammer |
| |
| * Noteworthy changes in release 2.6.4 (2015-08-31) |
| This is a minor release in terms of features. But in terms of test |
| coverage and stability it is a vast improvement over previous versions |
| of Liblouis. The new YAML based test suite contains more than a |
| million of validated translations. Every change in Liblouis is tested |
| against this corpus ensuring the change doesn't break anything. |
| |
| ** New features |
| - YAML based harness tests. Harness tests can now be written in simple |
| YAML notation and they are integrated with the normal `make check` |
| command. They can be used for both ucs2 and ucs4 and no Python is |
| required. Thanks to Christian Egli. |
| |
| ** Bug fixes |
| - Use a separate gnulib instance for the library and the tools. Use |
| the strndup module to avoid build problems on windows. |
| - Fix a problem with the nocross opcode when used in combination with |
| the opcodes nocont and compbrl, thanks to Bue Vester-Andersen. |
| - Fix a problem with the decoding of the harness test files. Thanks to |
| Bert Frees. |
| - Fix numerous problems in the way braille indicators are handled. |
| There is now a safe version of the checkAttr function which makes |
| sure that no attributes are checked beyond the boundaries of the |
| currentInput. This fixes the random behavior with tests where the |
| emphasis extends to the end of the input string. Thanks to Christian |
| Egli. |
| |
| ** Other changes |
| - if found use texi2any to build the documentation, thanks to Martin |
| Michlmayr. |
| - Fix permissions of Korean tables, thanks to Peter Lundblad. |

| Zvonimir Stanecic |
| |
| * Noteworthy changes in release 2.6.3 (2015-06-01) |
| Given the release number you might think this is only a minor release. |
| However looking at the number of developers who contributed to it and |
| the number of pull requests and issues that were solved this turns out |
| to be a very impressive and solid release. Most prominently we have a |
| new function to discover tables based on meta data in table headers. |
| Also makeinfo is no longer required to build liblouis. And lastly we |
| have numerous improvements in Braille tables such as Korean, |
| Vietnamese and UEB to name just a few. |
| |
| ** New features |
| - [beta] The new function lou_findTable can be used for table |
| discovery based on meta data in table headers. Thanks to Bert Frees. |
| - The Python API now has a new function to check tables aptly named |
| ~checkTable~. Thanks to Davy Kager. |
| |
| ** Bug fixes |
| - Fixed a problem in resolveTable when using a Java resolver, thanks |
| to Bert Frees |
| |
| ** Other changes |
| - The build dependency on makeinfo is now optional. If it is not |
| installed we simply do not build the documentation. |
| |
| ** Braille table improvements |
| - Improvements to Bengali, Devanagari, Kannada, Gujarati, Malayalam, |
| Telugu and Oriya, thanks to Sreeja Param |
| - Corrections and improvements made to en-GB tables thanks to Paul |
| Wood |
| - Vast restructuring to Korean tables. In 2006 the Institute for Korean |
| Braille modified some dots in Korean Braille. Specifically, some |
| punctuation dots are now based on English. To accommodate this change |
| and to retain the old tables, the Korean table set was revised as |
| follows: |
| - Added three files: ko-chars, the Korean characters dictionary, and |
| rules for g1 and g2. |
| - ko-g1 and ko-g2 are now interface files that includes needed |
| files. |
| - Added three files for Korean Braille 2006 revision along with a |
| test harness. |
| - New table for Polish 8 dot computer braille. Thanks to Karol Pecyna. |
| - New table for Vietnamese 6 dot. Thanks to Harri Pasanen. |
| - Corrections and improvements made to UEB tables thanks to Paul Wood |
| - Typeform passage indicators |
| - Degree sign |
| - Dash signs |
| - Math signs |
| - Accent modifiers |
| - Accented letters |
| |
| * Noteworthy changes in release 2.6.2 (2015-03-02) |
| This release, which was mostly pushed out the door by Bert and Mesar, |
| fixes a long standing emphasis bug, adds more functionality to the |
| harness test suite and improves, as usual, on Braille tables. Notably |
| there is a brand new finish table backed by Celia. |
| |
| ** New features |
| - Harness tests now can test for typeform differences. |
| |
| ** Bug fixes |
| - Fix for emphasis bug, thanks to Michael Gray |
| |

| - Corrections and additional test cases for Hungarian grade 1, thanks |
| to Hammer Attila. |
| - New 6-dot table for Finnish thanks to Jukka Eerikäinen from |
| Celia. The existing tables for Finnish were 8-dot, but there is an |
| official specification only for 6-dot braille in Finnish. |
| |
| * Noteworthy changes in release 2.6.1 (2014-12-01) |
| This release focuses on table and documentation improvements. The |
| documentation has been restructured to cater to people starting with |
| writing Braille tables. End users will see improvements to Braille for |
| Danish, Dutch, Hungarian, Irish and UK English. |
| |

| |
| * Noteworthy changes in release 2.6.0 (2014-09-01) |
| This is the first release by the new maintainer team. A lot of work by |
| people from across the community contributed to this release. There |
| are massive additions and updates to the Braille tables (e.g. |
| Afrikaans, Hebrew, many Indian languages, Korean) and also changes to |
| the C API to enable call backs for error messages and warnings. |
| |
| ** New features |
| *** New Braille tables |
| - Tables for Afrikaans, Cherokee, Hawaiian, Maori, Sotho and Tswana |
| were donated by Greg Kearney. Afrikaans, Cherokee, Maori and Hawaiian |
| all are grade 1 tables and with the exception of Cherokee were |
| derived from World Braille Usage 2013. The Cherokee was taken from |
| the specification published at www.cbtbc.org/cherokee/. |
| *** Logging callback |
| There is now a callback system in place to get error messages and |
| warnings. This can be used from programs that use liblouis to log |
| warnings for example. |
| |
| ** Bug fixes |
| - fix back translation problems when word gets split in unusual places |
| causing back translation of whole words for example K5 back |
| translates to Knowledgeen, M>k back translates to Moreark, and M5 |
| back translates to Moren. This caused over 8400 extra back |
| translation errors in en-us-g2 and 5000 in en-ueb-g2. Thanks to Ken |
| Perry. |
| - Fixed bug to prevent removal of \xffff between largesign rules. This |
| solves a Liblouisutdml bug where \xffff is used as a segment |
| delimiter. |
| - Fixed a bug in back translation, when a letsign was encountered, the |
| letsign was being applied beyond the element it applied to. |
| - Fix memory leaks in the default table resolver introduced in the |
| previous release. |
| - Fixes to the build system by Simon Aittamaa |
| |
| ** Braille table improvements |
| - Major improvements to Indian tables thanks to the Indian National |
| Institute for Visually Handicapped, in particular Dipendra Manocha, |
| Mesar Hameed, Dinesh Kaushall and Sreeja Parameswaran: |
| - Corrected opcodes for letters, punctuation marks, digits, signs |
| etc. |
| - Updated braille codes according to prescribed braille codes for |
| each Unicode character by the Braille Council of India for all |
| Indian languages. |
| - defined rules for dealing with Nukhta character in Hindi table |
| - defined rule to insert dot-1 between consonant followed by full |
| vowel character in all Indian Languages |
| - defined rules for shifting of halant character before the |
| consonant. This character is placed after the consonant in normal |
| typing but need to be before the consonant in braille. This rule |
| is applicable for all Indian languages. |
| - defined rules for two conjunct characters "ksha and gya" used in |
| all Indian Languages for which there are specific codes in |
| Braille. |
| - New Hebrew table that is based on the new unified Hebrew Braille |
| code standard that was put together on January 2014 after a |
| conference with all of the specialists in this field in Israel. It |
| includes improved representation of Hebrew letters, special letters |
| that are called Nikud, and punctuation symbols. The old Braille |
| standard is not relevant any more. Thanks to Adi Kushnir. |
| - UEB table fixes: Fix ity contraction, fixed the missing end word |
| contraction ;n ;d sign 46. thanks to Ken Perry. |
| - Fix for Norwegian where letsign is affecting some extra characters |
| thanks to Lars Bjørndal |
| - Much improved hyphenation for Norwegian thanks to Lars Bjørndal |

| number and strings such as 5-inch-diameter and 25-year-old-man |
| should now back-translate correctly. Thanks to John Boyer. |
| - Fixed a problem with syllable opcode. Thanks to John Boyer. |
| - Fix warnings with gcc 4.8.2. Thanks to Peter Lundblad. |
| - When a table is specified with an absolute or relative path, the |
| "includes" in that table will now work as expected, meaning files |
| in the same directory will be found. |

| rules have been used to perform a translation. Also along with other |
| new tables the long awaited table for UEB is finally here. |
| |
| ** New features |
| *** New tool to trace rule application |
| There is a new tool (lou_trace) which helps to trace which rules |
| have been used to perform a Braille translation. This is helpful |
| for writing Braille tables. See the documentation for more |
| information. |
| *** New Braille tables |
| - Inuktitut grade 1, thanks to Greg Kearney. |
| - UEB grade 1 and 2, thanks to Joseph Lee. These tables replace |
| the old UEB tables (UEBC-g1.utb and UEBC-g2.ctb). |
| - Korean table thanks to Joseph Lee |
| |
| ** Braille Table Improvements |
| - da-dk-g2.ctb, fixes for transposed â, å, æ, ä, ø and ö, |
| corrected/improved harness tests. |

| output characters. |
| |
| * Noteworthy changes in release 2.5.0 (2012-9-10) |
| |
| This release contains a tremendous amount of work many developers. |
| Many long standing bugs have been fixed. The tables can finally be in |
| UTF-8. A grand table cleanup removed duplication from the tables. |
| There are now two extensive test frameworks for table writers. A |
| number of new tables have been contributed on top of the usual |
| assortment of table improvements. Thanks to all of this liblouis has |
| already seen quite a bit of uptake in a number of places, notably the |
| new DAISY pipeline will ship with this release of liblouis. |
| |
| NOTE: If you have private tables you might want to migrate them to |
| utf-8. To do this just use iconv as follows: |
| |
| $ iconv -f latin-1 -t utf-8 <input >output |
| |
| ** New features |
| *** New Braille tables |
| - Estonian grade 0, thanks to Jürgen Dengo. |
| - Portuguese 8 dot Computer braille, Thanks to Rui Fontes |
| *** UTF-8 support in tables |
| Braille tables can now contain UTF-8 in the opcode arguments. |
| *** Improvements to the python bindings |
| All constants defined in liblouis.h are now exposed in the bindings. |
| *** Add a doctest infrastructure |
| These tests are based on the Python doctest framework and are only |
| run if there is a Python interpreter on the system |
| *** Add a test harness |
| This test infrastructure allows the user to do table tests in a |
| simple and concise syntax. These tests are based on the Python |
| nose testing framework and are only run if either Python 2.x or |
| 3.x with the related nose python module is installed on the |
| system. See the documentation for more information. Thanks to |
| Mesar Hameed. |
| *** Add a test harness generator |
| A harness generator that uses simple text files with a little |
| formatting to help to generate the json harness files. The purpose |
| of this tool is to make it much easier and faster to add checks |
| for a given table. You are expected to read the generated harness |
| file and make necessary changes, the tool only helps you to get |
| the tests into the harness format, not check their validity. |
| *** Support for Python 3 in the Python bindings |
| The Python bindings now work for both Python 2 and Python 3. |
| Thanks to Michael Whapples. |
| |
| ** Improved C-based test framework |
| - Improved the test framework to be able to test translations |
| involving Unicode. |

| |
| ** Improved the documentation |
| - Document the test harness (json format, fields, flags). |
| - Document the use of Valgrind to find memory leaks |
| - Improve the documentation on the display opcode |
| |
| ** Bug fixes |
| - lou_allround and lou_translate now properly handle Unicode |
| characters |
| - Fix some issues reported by Valgrind |
| - Fix inputPos for situation where context and multipass opcodes |
| are involved |
| - Fixed a number of bugs with the letter, uppercase and lowercase |
| opcodes when dealing with Unicode |
| - Fixed a couple of bugs with hyphenation (documentation, Python |
| bindings and a number of buffer overruns in the C library). |
| Thanks Milan Zamazal <pdm@brailcom.org> for reporting this. |
| - Fix a bug in the $a. matcher in the multipass rules where only 32 |
| chars were matched. It now matches 0xffff chars. |
| - Fix a bug reported by James Teh related to pass1Only |
| |
| ** Braille Table Improvements |
| - all table files have consistent encoding, UTF-8. |
| - The grand table cleanup: Reorganize the tables to remove |
| duplication. Move common parts such as Latin letter, eight and |
| six dot digit definitions to separate files which are then |
| included. This should ease table maintenance. Thanks to Mesar Hameed. |
| - Fixes to de-de-comp8.ctb thanks to Aliminator83@gmail.com |
