Format scheduled task intervals

 ## 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.
 
+## 2.6.27 - 2026-08-14
+
+### Fixed
+
+- Scheduled task intervals now display the most appropriate exact unit, such as seconds, minutes, hours, or days, while keeping the sort order numeric.
+
+## 2.6.26 - 2026-08-10
+
+### Changed
+
+- API sources and RSS feeds now accept hours as an update interval unit, and the list and background task scheduling paths now format and convert that unit correctly.
+
+## 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
