 ## 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.

+## 2.6.23 - 2026-08-09
+
+### Fixed
+
+- API and RSS refresh jobs now notify affected player screens after a successful update, so API-backed slides pick up new data without waiting for a manual page reload.
+
 ## 2.6.22 - 2026-08-09
