 All notable changes to this project will be documented in this file.

+## 2.6.22 - 2026-08-09
+
+### Changed
+
+- Startup now logs the previously detected schema version, the current app version, and whether pending migrations exist.
+
+### Fixed
+
+- Direct-to-URL player sessions now generate and persist a stable onboarding device id in session storage, so connected screens can still be moved and renamed independently without going through the onboarding flow first.
+- The connected-clients move action now tolerates rows that only have a live connection id, which keeps move operations working for screens that skipped onboarding.
+
+## 2.6.21 - 2026-08-09
+
+### Changed
+
+- Startup now logs the previously detected schema version, the current app version, and whether migrations are required.
+- The schema documentation now reflects the timetable table rename, the new `o_app_state` table, and startup version tracking.
+- Timetable timezone placeholders now use `tz` for the short zone name and `tz_long` for the full IANA zone.
+
+## 2.6.20 - 2026-08-09
+
+### Changed
+
+- Startup now logs the previously detected schema version, the current app version, and whether migrations are required.
+
+## 2.6.19 - 2026-08-09
+
+### Changed
+
+- Timetable editor helpers, routes, and table layout now use timetable-specific naming and tighter card/table styling.
+- Connected clients now sort by client identity fields instead of the old IP-based ordering assumption.
+
+## 2.6.18 - 2026-08-09
+
+### Changed
+
+- Timetable tables were renamed from the old `schedule` names to `timetable` names, and existing databases now rename those tables during migration.
+- The timetable group editor now uses timetable-specific naming in its shared helpers and keeps the entries table aligned with the standard admin card/table layout.
+
+## 2.6.17 - 2026-08-09
+
+### Changed
+
+- Existing timetable groups and entries are now migrated to Europe/London, and timetable dates are rewritten to UTC using that source timezone so the wall-clock meaning stays intact.
+
+### Fixed
+
+- New timetable groups now default to Europe/London so the timetable editor and saved data start from the same timezone assumption as the migrated rows.
+
+## 2.6.16 - 2026-08-09
+
+### Changed
+
+- Timetable groups now store an IANA time zone and render their entry datetimes in that timetable time zone, so schedules keep the same wall-clock meaning when they are edited from another country.
+
+### Fixed
+
+- Timetable entry date inputs now round-trip through the timetable time zone instead of the browser locale, so saving from Florida while targeting Germany keeps the intended local times.
+
+## 2.6.15 - 2026-08-08
+
+### Fixed
+
+- Slide update media sync on the player now removes uploads that were removed from the slide, so player storage stays aligned with the current slide content.
+- Routine player and player-bridge media upload/delete logs were removed to keep remote player and bridge operation quieter.
+- Background task descriptions no longer repeat the player slug when the task key already ends with that player name.

+- `state_key` is the primary key.
+- `schema_version` is stored here so startup can detect the previously recorded schema version before deciding whether migrations need to run.

 ## Notes

 - The schema is initialized with `CREATE TABLE IF NOT EXISTS`, so new installs can start from an empty database.
 - `src/db/bootstrap.js` seeds the canvas size defaults, default permissions, and the default administrator role.
- The migration module stays in place for future releases, but this version treats the current schema as the install baseline.
+- `src/db/migrations.js` records the current schema version in `o_app_state` during startup so later launches can tell whether an update is happening.
