ISC
* Wed Jul 03 2024 llyyr@yukari.in
- Update to 0.17.3:
* Fix 0.17.2 regression in the fontconfig fontprovider leading to
undesirable widths being chosen from large typographic families
* Fix configure generated with slibtool-provided autoconf macros
* Fix make check for shared-only builds
* Constify some API parameters in a backwards-compatible manner
* Add new ass_malloc and ass_free API functions
* Tweak default optimization flags
* Speed up parsing of events with very long override blocks
* Improve handling of HarfBuzz-related failures
- reintroduce 'make check' as the issue has been fixed upstream
* Tue May 28 2024 llyyr@yukari.in
- Update to 0.17.2:
* This release brings optimized assembly routines for aarch64,
as well as numerous individual improvements and fixes.
* Detailed Changes:
- Fix rendering of \h in certain cases
- Fix a minor memory leak in the CoreText and DirectWrite font provider
- Fix wrong ASS_Image dimensions for huge BorderStyle=4 backgrounds
potentially leading to out of bound reads by API users
- Improve quality of animated rectangular clips
- Improve accuracy of cache limits
- Full-Unicode cmaps are now always preferred
- Improve font selection compatibility in the DirectWrite font provider
- Improved documentation
- Updating selective overrides now forces a cache clear to avoid issues
with outdated caches
- Frame and storage resolutions are now limited to what a single ASS_Image
can represent
- make check now runs checkasm if assembly is enabled
- CoreText can now be used on Mac OS X 10.5
- Meson/muon is now offered as a secondary build system bringing back
first-party MSVC support
- Note however it is not at feature parity with autotools in all cases
- aarch64: add optimized assembly routines covering the same set as on x86;
they work on both little and big endian systems
- x86: add SSSE3 versions of some assembly routines to help CPUs without
AVX2
- x86: it is now possible to build binaries with optimized assembly an
SHSTK support
- Improve VSFilter compatibility
- 'make check' is broken for --disable-static builds because checkasm needs to
access symbols that aren't part of the public API, so just disable it.
* Mon Nov 27 2023 llyyr.public@gmail.com
- Require libunibreak during build for better linebreaking of
unicode text.
* Sun Mar 19 2023 dmueller@suse.com
- update to 0.17.1:
* Fix buffer overread if soft-wrapping occurred and
ASS_FEATURE_WHOLE_TEXT_LAYOUT was enabled via API or due
to Encoding -1
* x86: detect GNU Hurd and configure NASM appropriately
* Wed Dec 07 2022 dmueller@suse.com
- update to 0.17.0:
* This release’s major feature is the addition of a new ASS ScriptInfo
header pair: LayoutResX and LayoutResY. The introduction has been
coordinated with active VSFilters and will soon be available in xy-
VSFilter and XySubFilter as well.
* Since the beginning, many features in ASS scale relative to or are
otherwise affected by the storage resolution of the video file the subs
are bundled with. Adjusting subs for different video resolutions
traditionally took non-trivial effort. Of course this behavior must be
kept by default to preserve compatibility with existing files. But now,
setting both of the new headers to a positive, non-zero value will
replace the video storage resolution with the specified resolution for
the whole file, allowing easy reuse across all encodes of the same
display aspect ratio. This includes PAR effects, so reuse across
anamorphic and non-anamorphic releases is possible too.
* Detailed Changes:
* Fix various parts relating to automatic linebreaking
* Fix rendering when hinting was enabled and fontsizes or scales are zero
* Switch build to a non-recursive setup for improved parallelism
* Improve quality of SSA Effects movement
* Further documentation improvements
* Completely invalid Events are now discarded during parsing
* Introduction of LayoutRes{X,Y} script headers
* New AlphaLevel style override to set all alpha values while keeping the
color
* Add ASS_FEATURE_WRAP_UNICODE to allow automatic linebreaks in accordance
with the Unicode line breaking algorithm instead of ASS' much stricter
breaking rules. For the feature to be available at runtime, libass must
be linked against the new optional dependency libunibreak.
* Improve VSFilter compatibility:
* Fix premature truncation of animated alphas (was a 0.15.0 regression)
* Fix handling of small delay parameters for legacy SSA Effects
* Fix x-scaling with PlayResX
* Fix x-scaling for anamorphic video (except for \be whose scaling remains
buggy in general)
* Support SSA's AlphaLevel style field
* Support the \kt override tag from VSFilter's v4++ set
* Parse ScriptType headers
* Parse integer header, style and event field values like VSFilter
* Ignore trailing whitespace in an event's text
* Wed May 18 2022 dimstar@opensuse.org
- Update to version 0.16.0:
+ Fix crashes with fonts missing Postscript names and without one
being synthesised by the font provider.
+ Fix crashes on negative fontsizes and some overflows.
+ Fix a rare memory leak introduced in 0.13.0.
+ x86: Fix potential buffer over-read by 16 bytes with AVX2
assembly when large tiles are not enabled (the default).
+ x86: Fix PIC flags not being interpreted by the assembler,
breaking the asm-enabled build setup on NetBSD and OpenBSD. On
32-bit x86, if the toolchain requires PIC objects and relies on
compiler defaults to get PIC implicitly, you need to pass
- -with-pic to configure to ensure NASM always produces PIC
objects.
+ x86: Fix AVX support not being detected on non-Intel CPUs and
some VMs.
+ x86: Fix CPUID being used on CPUs not supporting the
instruction (<= i486) and the way it is used for CPUs with less
than 7 CPUID-leafs which could lead to crashes due to illegal
instructions.

* Wed Dec 16 2015 jengelh@inai.de
- Update summary/description
* Mon Dec 07 2015 jengelh@inai.de
- Update RPM groups
* Sun Nov 22 2015 mpluskal@suse.com
- Update to 0.13.0
* Add native font selection backends for OSX (CoreText) and
Windows (DirectWrite). You can now run libass without
fontconfig on these platforms. This fixes problems with
fontconfig behaving badly on these platforms (it could take
minutes to scan all system fonts). Even on Linux, this speeds
up loading of embedded fonts (such as provided by
ass_add_font()). The DirectWrite backend only works on Windows
Vista and later. On XP, fontconfig is still needed. libass can
be compiled with both DirectWrite and fontconfig, and then it
will fallback to fontconfig automatically if DirectWrite is not
available at runtime.
* Add ass_get_available_font_providers() API function.
* Change the 4th parameter of ass_set_fonts(). This now selects
the font provider. This is somewhat backwards compatible with
the old behavior, but if you ever passed values other than 0
or 1, your application might break with this libass release.
* The ass_fonts_update() function now does nothing. It's kept
for backward compatibility only.
* Much faster gaussian blur. This can bring a large speedup with
big blurred signs and such.
* Drop ENCA support
* Bug fixes
+ Fix compilation of the freetype rasterizer (disabled by
default)
+ Fix rendering with some cases of consecutive line breaks
(\N\N).
+ Fix some memory allocation failure checks
+ Avoid system locale dependent behavior by reinventing some
standard C functions
+ Fix rendering errors with strikes (GH #193)
