v1.3.0

[1.3.0] - 2026-04-10

Fixed

• Race conditions in meditation generation lifecycle: stale polling and completion checks no longer corrupt state when pressing "New" or rapidly re-generating
• Missing cancel affordance during loading phase: "New" button now appears alongside spinner so users can abort at any stage (loading, streaming, playback)
• Small screen layout: playback and loading controls stack vertically on narrow viewports
• Insufficient spacing between Record Audio and Submit Float buttons on small screens

Added

• Generation session tracking with AbortController and generation ID to prevent stale async work
• Centralized handleNewMeditation callback for clean abort + state reset across all playback modes

v1.2.0

[1.2.0] - 2026-03-20

Changed

• Upgraded Expo 52→55, React 18.2→19.2, React Native 0.74→0.84, Jest 29→30
• Migrated test infrastructure from monorepo root into frontend/ workspace
• Replaced deprecated react-test-renderer with @testing-library/react-native
• Jest config uses projects to separate unit and integration test environments

Fixed

• Jest 30 teardown crashes from requestAnimationFrame (timer cleanup in afterEach)
• Expo 55 globals (TextEncoder, structuredClone, __ExpoImportMetaRegistry) polyfilled for Jest

• Integration test setup.ts wired to run via Jest projects setupFilesAfterEnv
• expo-file-system mock extended with EncodingType.Base64

v1.1.0

[1.1.0] - 2026-03-15

Added

• Changelog-driven release automation: pushing CHANGELOG.md to main creates tags and GitHub releases

• Commitlint with conventional commits enforcement and husky pre-commit hooks
• One-command npm run setup for development environment
• End-to-end handler test for summary flow

Fixed

• Backend test reliability: mock Lambda async invocation properly in unit tests
• Unsafe SummaryResponse-to-Incident cast replaced with explicit mapping
• S3 failure handling: raise on _save_job errors
• FFmpeg subprocess timeouts for streaming and audio mixing
• S3 list_objects pagination for large result sets
• Deprecated expo-permissions replaced with expo-notifications API

Changed

• Backend settings converted to Pydantic BaseSettings
• Legacy request wrapper layer removed in favor of direct Pydantic validation
• Removed unused domain model layer, exception classes, and dead code
