Key Changes

Fixed

• Ghost Updates: Resolved an issue where native DNF packages (like Brave Browser) would continuously reappear in the update list after successfully updating, caused by stale cache queries ([BUG] Update apps doesnt work #3).
• Flatpak Privilege Blindspot: Fixed an issue where the updater could not detect or update user-installed flatpaks. Flatpak updates now seamlessly integrate with the system polkit for native permission handling ([BUG] Update apps doesnt work #3).
• System App Protection: Fixed a bug where third-party apps were incorrectly flagged as protected system applications, which prevented users from uninstalling them ([BUG] Manage Apps doesn't work #2).
• KDE Dock Icon: Fixed missing app icon in the KDE panel. ([BUG] App Icon Missing #1) by @Joy-Majumder in Fix KDE dock icon; add macOS build stubs #4.
• Queue Manager UX: Fixed a bug where a single failed application update would wipe the entire operations queue and force a false "Success" screen. Failed operations now correctly stay in the queue with visible error badges.
• Queue Operation Clashing: Fixed an issue where restarting an operation in the queue manager would overwrite previous operations. Every queued action now generates a mathematically unique ID.
