 # Changelog
 
+## 26.1.8
+- 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
+- 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.
+- Changed the reboot confirmation and result UI to non-blocking sheets/banner feedback so failures no longer trap the app in modal dialogs.
+- 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
 - 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.
