* Mon Jan 16 2023 Dirk Müller <dmueller@suse.com>
- Update to version 3.24.0:
+ This release contains major updates to Hungarian, UEB, and
Chinese bopomofo braille. Danish has been completely reworked
and there is now support for the Danish braille standard 2022.
There are also some new tables so that liblouis can now
generate Georgian computer braille, Swahili (Kenya) and
Chichewa (Malawi). Aside from that there is the usual
assortment of code cleanups and bug fixes.
+ For a detailed list of all the changes refer to
https://github.com/liblouis/liblouis/milestone/34?closed=1
+ Braille table improvements:
- New grade 1, 1.2, 1.3, 1.4, 1.5 and 2 tables for Swahili
(Kenya) and grade 1 table for Chichewa (Malawi).
- Improvements to Hungarian.
- Update braille patterns of some Chinese characters and
phrases in the Chinese bopomofo braille table
- Add experimental Georgian computer braille table
- Updated the Danish tables to the new 2022 Danish braille
standard
- Limited contraction level (grade 2l or 1.5) is no longer part
of the Danish braille standard 2022.
- There is no longer any need for "literary" tables. In Danish
braille, capital letters are now always indicated, and steps
have been taken in the standard to ensure better
back-translation.
- As requested by The Danish Braille Committee, the tables for
the 1993 standard will be kept as an option for at least a
year. All the 1993 tables have been renamed to include
"_1993" in the filename, so the new tables will be used as
default.
- Improvements to UEB.
- Add new sign for German sharp S (ICEB July 2022)
- Fix a couple of acronyms which require grade 1 indicator
(LLB, LLP)
- Fix placement of numeral sign in letters comma digits
- Review rules for "under" and "there" contractions
* Sat Oct 01 2022 Dirk Müller <dmueller@suse.com>
- Update to version 3.23.0:
+ Fix a problem in the parsing of faulty unbalanced context
expressions.
+ Fix a buffer overflow problem when ~output.length~ is larger
than ~input.length~.
+ Fix an endless loop in the handling of computer braille.
+ Braille table improvements:
- Remove computer braille from Japanese Kantenji as it is not
part of the standard.
- Bring Swedish tables up to date with the latest standard
published by Punktskriftsnämnden (the Swedish Braille
Authority) in 2009. The table for uncontracted braille was
replaced and new tables for (partially and fully) contracted
braille have been added.
- Improvements to Hungarian (added more exceptions) and
migration to the ~nonumsign~ opcode.
- Fixed a bug in the Ukrainian table that led to wrong
translation of some uppercase letters.
- Augment the UEB grade 2 tables to resolve an ambiguity
between lower groupsigns and punctuation at the beginning of
words by placing a letter sign at the front of punctuation.
This resolves an ambiguity between, for example, "discount"
and ".count".
- Add a new table for /Chinese Common Braille Scheme/ which is
a type of braille used for spelling Mandarin Chinese. It is a
variant of the /Chinese Current Braille System/ but has more
perfect marking rules and produces less ambiguity than the
latter. For more information see the comments in
~zhcn-cbs.ctb~.
- Updates to the Chinese bopomofo braille table:
. Update braille patterns of some Chinese characters and
phrases
. Add braille patterns for various Greek symbols
. Add "Math rules" section and the mixed number rule
. Add braille patterns for ☐ (⣏⣀⣹), ☑ (⣏⣿⣹), and ☒ (⣏⣭⣹)
- New table for Kinyarwanda braille
- New table for Luganda braille
- Improvements to the Russian contracted braille table:
. Now prefixes "из" and "без" are correctly contracted
before hard sign (ъ).
. Fixed a contraction for word "кое-где", now it is
contracted according to rules.
. Other minor fixes and improvements.
* Fri Jun 24 2022 Dominique Leuenberger <dimstar@opensuse.org>
- Update to version 3.22.0:
+ This is a major release. On the Braille tables side there is a
new table for German grade 2 with capitalization and there are
updates to the Dutch, German Hungarian, Punjabi, Russian, UK
Braille Computer Notation and Slovak tables.
+ A new opcode to indicate the end of a number where the number
doesn't end at a space character
+ A lot of work was put into checking for and fixing memory
problems.
- Drop info file handling in post/postun of doc package: inf files
are handled by file triggers nowadays.
- Also remove the install_info_prereq prereq (which was, for that
matter, even on the wrong package).
- Drop liblouis-CVE-2022-26981.patch and
liblouis-CVE-2022-31783.patch: fixed upstream.
* Thu Jun 02 2022 Michael Gorse <mgorse@suse.com>

write in compileRule (boo#1200120 CVE-2022-31783).
* Sun Apr 10 2022 Dirk Müller <dmueller@suse.com>
- update to 3.21.0:
* New table for German 6-dot computer braille thanks to the Swiss Library for
the Blind, Visually Impaired and Print Disabled
* see http://liblouis.org/liblouis/2022/03/07/liblouis-release-3.21.0.html
for list of bugfixes
* Mon Jan 31 2022 Dirk Müller <dmueller@suse.com>
- update to 3.20.0:
* This is a major release. Not only in terms of table additions and
updates but also in the way the tables are written. Bert has replaced the
~uplow~ opcode with a more generalized ~base~ opcode. This clears
up the path for a more generalized handling of emphasis and uppercase
characters. In the course of this simplification some bugs with
computer braille were discovered and fixed.
* For this release Bert Frees has been hard at work to clean up the code
base. He fixed a few bugs one of which was causing memory corruption.
Others have contributed corrections to braille tables or even provided
new tables. For example there are now tables for Tshivenda and for
Russian contracted braille.
* 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.
* This release stands in the tradition of small incremental improvements
that make it another fine and solid release. Andrey Yakuboy put in a
lot of work to improve Russian literary and computer braille. He also
provided a new table for Belarusian uncontracted and computer braille.
Aside from that there are numerous improvements in Braille tables such
as French, Polish and Urdu. The documentation has been improved as has
the table meta marking the tables whether they are geared towards
forward or backwards translation. I'd like to thank everybody for
helping to bring liblouis forward.
* Thu Feb 18 2021 Dirk Müller <dmueller@suse.com>
- update to 3.16.1:
* * New features

been added.
- The table now includes the international phonetic alphabet table.
- Punctuation after digits and fractions is now marked with dot 6 to
avoid ambiguities.
- Other changes to conform better with Russian braille rules.
- A new table that indicates capital letters was added. This is the
new recommended Russian table for braille display users.
- Removed the old ~ru-ru-g1.utb~ in favor of ~ru-litbrl.ctb~ and
~ru-litbrl-detailed.utb~.
* * Other changes
- Support for Python 2 has been removed.
* Sun Sep 20 2020 Dirk Mueller <dmueller@suse.com>
- Update to version 3.15.0:
+ Long list of changes, see included NEWS file.
- Change sover to 20, following upstreams ABI bump.
* Tue Nov 19 2019 Michael Gorse <mgorse@suse.com>
- Update to version 3.11.0:
+ A tremendous amount of work by Dave Mielke and Bert Frees
has gone into this release. They have improved liblouis for use
on note taker devices, for backwards translation and a number
of languages. Many other contributors (listed below) have also
helped in fixing bugs and improving braille tables, such as
Dutch, Mongolian, Polish, Ancient Greek, Danish, Irish,
Chinese, and American Braille Computer Code.
+ New features:
- Enable ~always~ rules with a single character and a single
braille cell for back-translation.
- Implement ~noUndefined~ mode for forward translation.
- Use fallback braille representations (NABCC) for rendering
undefined characters in hexadecimal notation.
- Always render undefined characters, also ASCII characters, in
hexadecimal notation.
- Add a new metadata field ~index-name~ for selecting a table
from a list fast and efficiently. It has the most important
information first and no redundant information. It should
look nice when sorted. This in contrast to the existing
~display-name~ field which is for describing a table
accurately and should sound good.
+ Bug fixes:
- Don't let a caps passage end on a word with no letters.
- Handle word resets in the last word of an caps or emphasis
passage if the end indicator was placed before the word.
- Never convert to lowercase if ~capsletter~ is not defined.
- Fix position mapping for back-translation when ~noUndefined~
mode is active.
- Fix bug where a translation would hang on words that match
both a ~nocont~ and a ~repeated~ rule.
- Fix bug where the effect of ~capsnocont~ would leak to the
next word if that word starts with a capital.
+ Braille table improvements.
+ Other changes:
- The python wrapper now encodes and decodes strings to/from
UTF-16 and UTF-32 using the surrogatepass error handler. This
ensures that single UTF-16 surrogate characters are processed
correctly by the wrapper and don't raise an encoding/decoding
error.
- Metadata keys and values are now case insensitive.
- Remove ~unicodedefs.cti~. It was obsolete and never meant
to be included by any tables. Instead use the online
references as mentioned in the documentation now.
- ~lou_checkyaml~ test reporting has been improved.
- Hyphenation tables have been removed from tables except
those needed for ~nocross~ rules.
- ~lou_hyphenate~ can now handle more than just words
(sequences of letters), e.g compound words.
+ Deprecation notice: - The ~noUndefinedDots~ mode has been
renamed to ~noUndefined~. For backwards compatibility
~noUndefinedDots~ is still available in the header file and in
the Python bindings, as an alias for ~noUndefined~.
+ Backwards incompatible changes: None.
+ Changes in version 3.10.0:
+ This release comes across as quiet, containing just the usual
assortment of braille table improvements, cleanups, bug fixes
and the classic buffer overflow patches. But beware, a lot has
happened behind the scenes. Bert and Davy have been adding a
new opcode to handle special emphasis situations. A number of
annoying restrictions with regards to names, such as class
names have been removed thank to Bert. And lastly
also thanks to Bert it is now possible to define inline display
tables in your YAML tests.
+ New features:
- Add a new opcode ~emphmodechars~.
+ Bug fixes
- Remove memoization in ~checkAttr~. It wasn't implemented
correctly, caused some weird bugs and probably didn't do much
for performance.
- Fix multiple buffer overflows in ~compilePassOpcode~.
- Fix a build problem when building without libyaml.
+ Braille table improvements.
+ Other changes:
- Remove various restrictions on which characters and braille
cells can be used in translation rules.
- Remove some code duplication in ~pattern.c~.
- It is now also possible to define inline tables when a display
table has been defined.
+ Deprecation notice: None.
+ Backwards incompatible changes: None.
+ Changes in version 3.9.0:
+ This release has seen a tremendous amount of work by Bert
Frees. He was instrumental in pushing the improvements for
Latvian, Norwegian and Slovenian. But most prominently he
pushed the big change for space and control character
handling through the door. These characters are now no longer
hard coded in liblouis. This should solve a few long standing
issues. Other than that there is the usual assortment of code
improvements and cleanups.
+ New features: None.
+ Bug fixes:
- Fix a problem in the callback registration in the Python
bindings.
- Fixed memory leaks created by block scope compound literals.
- The hard coded rules dealing with white space have been
replaced with a normal table that is included in all tables.
This fixes a number of bugs to do with space and control
characters. This (big) change has been brewing for a couple
of releases and has finally landed.
+ Braille table improvements.
+ Other changes:
- Don't search for tables in ~/usr/local/share/liblouis/tables~
(or the Windows equivalent) if ~LOUIS_TABLEPATH~ is set.
- The log levels in ~liblouis.h~ are no longer exposed as
~LOG_FOO~ but instead are now prefixed. So ~LOG_WARN~ becomes
~LOU_LOG_WARN~ for example to issue a warning from a C
program using liblouis. The actual values remain the same,
so the ABI remains stable.
* * Deprecation notice
- The ~locale~ opcode was never implemented and was just
silently ignored. It is now removed from the tables and a
warning will be issued if it is found in a table.
- Drop
gcc9-fixed-memory-leaks-created-by-block-scope-compound-l.patch
fixed upstream.
- Sover is now 19.
* Fri Mar 29 2019 mgorse@suse.com
- Require libyaml-devel so that yaml tests are run (bsc#1130813).
* Fri Feb 22 2019 Martin Liška <mliska@suse.cz>
- Add gcc9-fixed-memory-leaks-created-by-block-scope-compound-l.patch
(boo#1122169).
* Wed Jan 16 2019 Martin Liška <mliska@suse.cz>
- Use %make_build in order to build the package in parallel way.
Add make check.
* Sun Jan 06 2019 bjorn.lie@gmail.com
- Update to version 3.8.0:
+ Noteworthy changes in this release: The major focus of this
release is on braille table updates. There are major updates to
German, Arabic, Chinese, Turkish, Dutch, Czech, Latvian,
Spanish and Ethiopic. Some of these new tables have only been
possible because Bert Frees fixed some nasty long standing bugs
behind the scene. Also there is the usual assortment of code
improvements and cleanups.
+ New features: None.
+ Bug fixes:
- Fix support more than 4 classes.
- Fix capitalization of words that match nocont rules.
+ Braille table improvements.
+ Other changes: Updated the lou_allround and lou_trace test
tools to include all the mode flags described in the
documentation of the lou_translateString() function.
+ Backwards incompatible changes: The pass1Only flag has been
deprecated for a while and is now removed from the code.
- Bump sover define to 17, following upstreams soname bump.
* Fri Sep 21 2018 mgorse@suse.com
- Update to version 3.7.0 (boo#1109319)
+ New features
- Added a new opcode ~midendnumericmodechars~. Characters
defined with this opcode can appear in the middle or at the
end of a number without canceling numeric mode.
+ Bug fixes
- Fix another stack-based buffer overflow in input parsing
reported by Henri Salo thanks to Christian Egli.
- Fix input/output positions for back-translation.
- Major improvements in the back-translation of capitalized words
- Fixed a problem in the back-translation of numbers in
conjunction with punctuation and letters.
- Fix a buffer overflow in ~matchCurrentInput~.
+ Braille table improvements
+ Other changes
- Added documentation of opcodes which were previously
introduced as part of the UEB work.
- Removal of the code for the /scripting language/ for
multipass opcodes. This code was originally introduced in
2012 but never documented. Consequently it was never used.
Meanwhile the original code for multipass opcodes was much
improved. So there is no more need for this (duplicate)
code and we are removing it.
+ New tables: zhcn-g1.ctb, zhcn-g2.ctb
- Drop CVE-2018-12085.patch: fixed upstream.

- Added CVE-2018-11410.patch: Fix a buffer overflow in table
parsing (bsc#1094685 CVE-2018-11410).
* Fri May 25 2018 kbabioch@suse.com
- Updated to version 3.5.0:
+ New features
- The same name can now be used in more than one ~class~ rule.
The effect is that both set of characters become part of that
one class.
+ Bug fixes
- Fix a regression in inputPositions thanks to Bert Frees
- Treat characters within the range ~compbrlStart~ and
~compbrlEnd~ as a special case. This fixes many if not most
of the problems with cursor position and the
~compbrlAtCursor~ mode. Thanks to Dave Mielke.
- Fix ~swapdd~ opcode thanks to Bert Frees
- Fix negation of attribute matcher in multipass expressions
thanks to Bert Frees
+ Braille table improvements
+ Backwards incompatible changes
- The translation mode ~comp8Dots~ has been removed as it was
never really implemented anyway
- Support for the ~pass1Only~ flag has now been removed. Thanks
to Bue Vester-Andersen.
- The old UEB tables ~UEBC-g1.ctb~ and ~UEBC-g2.ctb~ have been
removed as the have been superseded by ~en-ueb-g1.ctb~ and
~en-ueb-g2.ctb~.
- The french tables ~fr-2007.ctb~, ~fr-fr-g1.utb~,
~fr-fr-g2.ctb~, ~fr-ca-g1.utb~ and ~fr-ca-g2.ctb~ have been
removed. Use ~fr-bfu-comp6.utb~ for 6 dots literary,
~fr-bfu-comp8.utb~ for 8 dots computer and ~fr-bfu-g2.ctb~
for contracted braille instead.
- Updated to version 3.4.0:
+ 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.

boo#1056090 (CVE-2017-13743), and boo#1056088
(CVE-2017-13744)
+ Braille table improvements
- Changes from version 3.2.0:
+ Bug fixes
- Fix capsnocont opcode. Also mark capital letters with
capsletter symbol when capsnocont is defined but no
begcapsword indicator is defined.
- Fix the syllable opcode. It had been broken under some
circumstances since 3.0.
+ Other changes
+ Fix building of Python bindings when cross-compiling.
- lou_checkyaml is now only installed if libyaml is available.
- Enhance documentation on usage of display tables in
particular
in conjunction with Unicode dot patterns.
+ Braille table improvements
- Changes from version 3.1.0:
+ New features:
- 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.
- Add a noUndefinedDots mode to disable the output of dot
numbers when back-translating undefined patterns.
- 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.
- Add a partialTrans mode to specify that back-translation
input should be treated as an incomplete word. 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.
+ Bug fixes

size.
- Fix the \v escape sequence.
- The Python bindings now give a helpful error if liblouis has
been compiled with a different character size than Python.

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
- Documenting lou_charSize
+ Braille table improvements
+ License changes
- DocArch has agreed to re-license their tables, so we have 8
more tables under the LGPLv2.1+.

- Define python_sitelib: newer versions of python-rpm-macros
overwrite it to be python2 specific (python3 macros is called
python3_sitelib).
- To be on the safe side, define __python to python2 when not
building for python3.
* Mon Jun 06 2016 dimstar@opensuse.org
- Move %install_info_delete from postun to preun.
- Drop makeinfo BuildRequires: it's quite a big dependency and
the .info file is present in the tarball.

- Update to version 2.6.4:
+ 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.

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.
- Fix a problem with the decoding of the harness test files.
- 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.

- Fix warnings with gcc 4.8.2.
- 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.

. New Esperanto grade 1 table, using the x system for
accented letters.
- runHarness.py:
. Accept filename globs on the commandline to run specific
harness files. In tests/harness, one can do make <filename>
or make runall Removed from make check because these checks
are checking the validity of our tables, rather than
validity of the code.
+ Braille Table Improvements:
- da-dk-g2.ctb, mostly rewritten to use nocross and hyphenation
table.
- Most tables: removed the default collapse whitespace
statements, if you need to compress whitespace, consider
adding compress.ctb to the list of tables when processing.
- Corrections to Unified English Braille Code (Grade 1 and 2).
- Corrections to apostrophes in the Computer Spanish 8 dots
Braille table (Es-Es-G0.utb).

references to this table were updated.
+ Backwards incompatible changes:
- The feature that allowed a mapping between language code and
Braille table was removed as it contained a out-of-bounds
access bug, was never documented and probably never used.
