 # Changelog
 
-## 26.1.7
+## Unreleased (2026-04-21)
+- Added a new `Summary` tab with a denser dashboard layout inspired by infrastructure monitoring tools.
+- Added persisted metric history with SwiftData for CPU, memory, disk, and swap charts.
+- Added `Hour`, `Day`, `Week`, and `Month` ranges to summary charts.
+- Added CPU, memory, disk, and swap history widgets that expand across the available summary width.
+- Reworked `General` to remain the more traditional detailed information tab while `Summary` focuses on quick status and trends.
+- Isolated metric history into an app-specific SwiftData store and recover cleanly from incompatible history stores.
+- Fixed the summary CPU chart to use the summary payload's reported CPU percentage and allow values above `100%` with a dynamic Y axis.
+- Fixed excessive summary redraws by moving the interval indicator timer out of the main detail view so charts no longer refresh every second.
+- Added optional sidebar groups for hosts, including group creation, editing, deletion, and host assignment.
+- Added grouped host ordering, group reordering via drag and drop, and clearer visual feedback while moving groups.
+- Improved group header styling to better distinguish groups and ungrouped hosts in the sidebar.
+- Fixed a launch crash in grouped builds caused by async ping tasks writing back to stale array indexes after the server list changed.
+
+## 26.1.9 (2026-04-19)
+- Reduced idle CPU usage and energy impact by changing the interval indicator from a permanent 60 FPS timer to a 1-second update cadence.
+- Reset the interval indicator cleanly when the refresh interval changes or when the indicator is hidden.
+
+## 26.1.8 (2026-04-19)
+- Fixed a crash in `PingService` caused by concurrent mutation of shared ping state from multiple async ping tasks.
+- Moved ping state tracking and reboot suppression windows into an actor so ping success/failure handling is serialized safely.
+
+## 26.1.7 (2026-04-19)
 - Added remote reboot support for hosts running KeyHelp API 2.14 or newer.
 - Added a dedicated `APIv2_14` client and mapped 2.14+ hosts to it instead of treating them as API 2.13.
 - Fixed the reboot request to call `/api/v2/server/reboot` with the required JSON confirmation payload.
@@ -8,22 +30,22 @@
 - Improved API error messages by surfacing the server response body instead of only generic HTTP status codes.
 - Reduced expected reboot noise by suppressing ping checks for a short grace period after a reboot request.
 
-## 26.1.6
+## 26.1.6 (2026-04-19)
 - Publish Gitea releases as stable by default instead of pre-releases.
 - Update the Homebrew tap automatically after each successful release by rewriting the cask version and DMG checksum, then pushing the tap repo.
 - Simplified the README for end users by adding clear install options and trimming internal release-engineering details.
 - Ignore the local `homebrew-tap/` checkout in the main app repository.
 
-## 26.1.3
+## 26.1.3 (2026-01-03)
 - Fixed version handling for changelogs.
 
-## 26.1.2 (2025-01-03)

 - Synced version.json to 26.1.2.

 - Fixed changelog extraction in publish script.
 
-## 26.1.0 (2025-01-03)
