[0.6.6]

Added

  • RELEASE.md — canonical release-process documentation covering the mix.exs-driven trigger model, the patch-bump-default-with-mandatory- permission rule, CHANGELOG conventions, when a bump is warranted (new functionality, bug fixes, doc improvements, dep bumps) vs. when it isn't (CI tweaks, hook changes, internal refactors), the tests-and-docs-with-new-functionality non-negotiables, and the per-step idempotency of release.yml. Linked from mob_dev and mob_new CLAUDE.md by URL so the canonical process is one file.
  • .githooks/pre-push — committed pre-push hook that runs the cheap preflight (format + credo + warnings-as-errors) on every push and the full release preflight (test suite + mob.security_scan where present) only when mix.exs changed. Activate per-clone with git config core.hooksPath .githooks.
  • CLAUDE.md "Release flow" section linking to the new docs.

[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.
