+- 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
+    + 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
+
