 ## Versioning and releases
 
 - Treat `package.json` as the source of truth for the application version.
+- Keep `package.json`, `build/package.player.json`, and `build/package.web.json` on the same version number.
 - When the app version changes, update `CHANGELOG.md` in the same change.
 - Keep database migration versions aligned with the release they actually belong to.
 - If only part of a migration batch belongs to a newer release, split that batch into a separate migration entry instead of relabeling the earlier release.

 All notable changes to this project will be documented in this file.
 
+## 2.6.25 - 2026-08-10
+
+### Fixed
+
+- Screen group edit now keeps the slug locked after creation, so existing screen group URLs remain stable.
+
+## 2.6.24 - 2026-08-10
+
+### Fixed
+
+- Deferred playlist updates now keep the current slide index when the next playlist snapshot is applied, so playback no longer jumps back to the first slide mid-cycle.
+
+## 2.6.23 - 2026-08-09
+
+### Fixed
+
+- Dashboard quick-action and kiosk-launcher cards now use row spacing instead of extra card padding, so the layout stays consistent at large widths.
+- API and RSS refresh jobs now notify affected player screens only when the refreshed data actually changes, so unchanged polls no longer trigger redundant player refreshes.
+
+## 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

+- `state_key`, `state_value`, `created_at`, `modified_at`
+- `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.
