1.1.2

September 2026. No API change; upgrading is a version bump. Libass is
rebuilt from the same library versions.

Fixed

• Styled subtitles keep to a memory budget. Each libass renderer caches at
  most 2,000 glyphs and 24 MB of bitmaps instead of libass's desktop
  defaults, and a file's attached fonts are kept up to 64 MB in all; a font
  past that is skipped and falls back to CoreText.
• Choosing a subtitle track no longer blocks the main thread while libass
  starts, copies the fonts and parses a sidecar, or while the previous
  renderer finishes a frame. The plain text stays hidden meanwhile, so it
  never flashes up unstyled.
• ASS drawings (\p1 … \p0) no longer reach currentSubtitleText or the
  fallback cues as vector commands, and a signs-only sidecar made of drawings
  loads for libass instead of being rejected as empty.
• Libass no longer imports fstat: FreeType reads fonts through stdio and
  HarfBuzz is built without mmap, so neither calls a file-timestamp API
  covered by the privacy manifest. libavformat and libavutil still do, so a
  host's FileTimestamp declaration stays.
