v0.8.0

Breaking changes

• Permission capability reporting — PermissionStatus now includes Unavailable, and
  accessibility and microphone permission requests return PermissionRequestStatus. Unsupported
  platforms no longer report permissions as granted.
• Default image decoder set — default builds now enable GIF, JPEG, PNG, and WebP. AVIF, BMP,
  DDS, EXR, farbfeld, HDR, ICO, PNM, QOI, TGA, and TIFF remain available through their individual
  image-format-* features but must be enabled explicitly.

Features

• Screen-capture lifecycle — callers can opt into exactly-once Ended, Cancelled, or Failed
  notifications for streams that start successfully. Existing ScreenCaptureSource::stream
  implementations remain source-compatible.
• Accessibility contracts and testing — elements can expose form-control properties, ARIA
  descriptions, and keyboard shortcuts; test platforms can activate accessibility, dispatch
  assistive actions, and inspect a stable debug tree.
• Cross-platform visual artifacts — Linux WGPU and Windows DirectX backends can render scenes to
  images for visual tests, with native window sizing and offscreen Windows rendering handled by the
  test platform.
• Window and image behavior — applications can request attention for a specific window, update
  layer-shell exclusive zones at runtime, honor EXIF orientation for static images, and size
  auto-dimensioned window roots from the platform-provided viewport.

Fixes

• GPUI macro dependency resolution — aligns adabraka-gpui-macros with the 0.8 release line,
  resolves renamed facade/core dependencies, and lets mixed direct dependency graphs select the
  intended crate through [package.metadata.gpui-macros].
• macOS screen capture — releases native setup, startup-failure, and frame-callback resources
  so repeated screen-sharing attempts do not accumulate them.
• Wayland clipboard/selection serial — selection ownership now uses a dedicated press-derived
  serial instead of the largest serial across all kinds, preventing IME serials from poisoning
  clipboard ownership on Mutter/kWin after prolonged input-method use.
• Rendering and event safety — fixes truncated-text measurement reuse, nested deferred draws,
  reentrant Windows draws, arena clearing during draws, prompt click-through, and Windows text and
  atlas edge cases.
• Platform lifecycle hardening — retains delayed Linux tasks during shutdown, enables the
  Windows security APIs required by single-instance support, and deduplicates Wayland IME cursor
  commits.

Improvements

• Internal crate split — separates core, platform selection, Linux, macOS, Windows, and WGPU
  implementations while preserving adabraka-gpui as the downstream compatibility facade.
• Linux/WGPU resource profiles — new windows now apply
  GpuResourceBudget::instance_buffer_initial_size, including after GPU device recovery, while
  clamping the allocation to renderer and device limits.
• Rendering and scheduling efficiency — reduces border-only quad overdraw, shares macOS display
  links per display, uses the Win32 thread pool for Windows tasks, and upgrades Taffy to 0.12.2.
• Release verification — the canonical migration script verifies all eight package archives and
  runs semantic API comparison for the published public facade with a registry library baseline.
