+## [1.0.11] - 2026-08-10
+
+### Added
+
+- **Phase 1 test fixtures**: Media and playlist test fixtures in `backend/playout/testdata/` with ffmpeg generation commands documented in test headers.
+- **Phase 4 R2 integration**: `SyncToR2` now sets `CacheControl` + `ContentType` based on file extension (immutable segments, short-lived manifests). Three integration tests added.
+- **Phase 2 viewer tests**: Presence updates (join/leave/sorted), private DM flow, message rendering (system/self/other) in `main.test.ts` (27 total tests).
+- **Phase 3 admin tests**: Playlist management (save via PUT, error handling, sortable rendering) in `admin.test.ts` (31 total tests passing).
+
+### Changed
+
+- Exported `savePlaylist` and `renderPlaylistSortable` from `admin.ts` for testing.
+
