## [0.6.5]

### Fixed
- HexDocs source links pointed at the non-existent `main` branch — corrected to `master` so each `</>` glyph next to a heading now opens the actual source file in the GitHub repo.
- `mob_nif.zig` called the variadic `enif_make_list/2` (not exposed in `mob_erts.zig`) from the BT paired-list finisher; the Android arm64 build failed at link. Switched to the non-variadic `enif_make_list_from_array(env, &empty, 0)`.

### Added
- `.github/workflows/test.yml` — runs `mix test`, `mix format --check-formatted`, `mix credo --strict`, `mix erlfmt --check src/`, `xcrun clang-format`, `swiftlint`, and `mix deps.audit` on push to master and on every PR.
- `.github/workflows/release.yml` — on tag push, creates a GitHub Release whose body is the matching `## [X.Y.Z]` section from this changelog (falls back to auto-generated commit notes if the tag has no section).
- `PLAN.md` — three-layer CI + integration-test plan covering the gap between unit tests and on-device verification.

## [0.6.4]

### Added
- `Mob.GpuView` / `Mob.UI.gpu_view/1` — Metal fragment-shader surface on iOS. Host owns the vertex shader (full-screen quad with `v_uv`); user supplies an MSL fragment shader plus a list of uniforms packed at natural alignment into fragment-buffer slot 0. SwiftUI `MobGpuView` wraps an `MTKView` with a hash-keyed shader cache and a translucent red overlay for compile errors. iOS-only in this release; the Android GLES 3.0 backend ships in mob_new 0.3.1.
- `<GpuView>` tag whitelisted for both `priv/tags/ios.txt` and `priv/tags/android.txt`.

## [0.6.3]

### Fixed
- iOS camera sensor delivered frames in landscape-right by default — `Mob.Camera.start_frame_stream/2` was feeding 90°-rotated pixels to ML models, dropping classification accuracy enough that a jar appeared as "laptop 24%" instead of "cup 96%". `AVCaptureConnection.videoRotationAngle = 90` (iOS 17+) / `videoOrientation = .portrait` (older) is now set on both the preview layer and the data-output connection, so what the user sees and what the model sees are the same upright frame.

## [0.6.2]

### Added
- `Mob.Camera.start_frame_stream/2` and `stop_frame_stream/1` — push-driven per-frame delivery as `{:camera, :frame, %{bytes, width, height, format, timestamp_ms, dropped}}`. Defaults to 640×640 `rgb_f32` for direct Nx hand-off; caller-overridable width/height/format/facing and a software `throttle_ms` gate.

### Changed
- iOS camera now uses a single shared `AVCaptureSession` for preview and frame stream. The previous two-session design silently dropped frames because iOS allows only one active session per physical camera.
