1.1.0

September 2026. Adds API and one native library, Libass; nothing is removed
or changed, so upgrading is a version bump. A host that credits its
dependencies adds libass, FreeType, FriBidi and HarfBuzz
(Artifacts/Libass.README.md has the licences).

Added

• Styled ASS/SSA subtitles through libass 0.17.5, with FreeType, FriBidi and
  HarfBuzz: named styles, karaoke, \move, \fad, clips, rotation, borders
  and drawings, in the fonts the file carries as Matroska attachments, then
  CoreText's. Embedded tracks and sidecars alike. Frames arrive through
  currentSubtitleImages, as PGS bitmaps do, so an overlay that draws those
  needs no change; the text still feeds currentSubtitleText.
• EngineTuning.rendersStyledSubtitles, on by default. Off falls back to the
  engine's own cue renderer.
• MediaRequestAuthorization.additionalHeaders, for a server behind a
  forward-auth proxy (Cloudflare Access, Authelia, Authentik). They go with
  the credential to the server's origin only, and remove(from:) takes every
  one off a request that leaves it.
• 10-bit H.264 (High 10) decodes in software, since no Apple hardware decoder
  accepts it. It is recognised from the stream itself, so one whose metadata
  names no profile no longer reaches VideoToolbox and fails.
• A styledSubs field on the bench line: libass's render and composite cost
  per changed frame.
• Releases attach FriBidi's corresponding source, as they do FFmpeg's.

Fixed

• ASS and SSA sidecar files load. They were rejected as unsupported; their
  dialogue now parses with the same subset as embedded events.
