* Sun Mar 19 2023 Dirk Müller <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 Dirk Müller <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 Dominique Leuenberger <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.

of the same frame during collision handling
* Fix shift in vertical positioning of some right-to-left events
with \an4-6, \pos, \move or Scroll effects

- Update to version 0.15.0
* Fix backwards/VSFilter-incompatible font sizes with FreeType
2.10+
* Improve speed via better caching
* Require HarfBuzz unconditionally to ensure good shaping for
complex scripts
* ass_set_use_margins(true) now simply places text on the whole
screen instead of attempting to tie it to video positioning
(set by the margin values) and failing in various ways when
margins are used to implement pan & scan in a video player
* Add ass_track_set_feature() & catch-all
ASS_FEATURE_INCOMPATIBLE_EXTENSIONS
* Add ASS_FEATURE_BIDI_BRACKETS to enable Unicode 6.3+ bracket
matching when applying the Unicode Bidirectional Algorithm
(incompatible with VSFilter; requires libass built with
FriBidi 1.0+)
* Fix stack overflow on deeply nested \t tags
* Fix positioning of events with leading line breaks
* Fix small but nonzero \bord becoming \bord0 (regression in
0.14.0)
* Measure BorderStyle=4 box padding from glyph border, not
from glyph fill
* Scale everything from script resolution if storage size is
not set (including borders and shadows regardless of
ScaledBorderAndShadow)
* Fix the default aspect ratio calculation when neither
ass_set_pixel_aspect() nor ass_set_aspect_ratio() is called
* Multiple fixes for karaoke override tags
* Handle memory allocation failures better:
avoid some crashes and produce images closer to truth
* Avoid some integer overflows
* Add internal infrastructure for regression testing
* Improve VSFilter compatibility:
+ Treat invalid nested \t tags like VSFilter
+ Make \t(T,T,...) at time exactly T use the post-transition
values
+ Make lines stack more like they do in VSFilter
+ Default ScaledBorderAndShadow to 0 (like VSFilter),
except for subtitles that were produced by old FFmpeg/Libav

stroker)
