* Sun Mar 19 2023 Dirk Müller - 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 - 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 - 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.

* 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+)

* 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 + Make shadow positioning with 3D transforms match VSFilter\'s + Cut out glyphs from border & shadow in all the same cases as VSFilter + Match VSFilter on animated color tags with negative acceleration + Fix parsing of some files that VSFilter accepts but libass didn\'t by ignoring leading whitespace in each line of an ASS file or CodecPrivate + Improve font selection with CoreText + Stop faux-bolding fonts that are too bold to get faux bold in VSFilter + Ignore leading/trailing spaces when calculating height of nonblank lines + Match VSFilter on \\fade with large alpha value arguments + Stop splitting bitmaps on font substitution + Multiple fixes for Banner and Scroll effects + Multiple fixes for karaoke override tags
