+ReleaseNotes: "Note: This release is not digitally signed for convenience. Stable releases will always be signed.Changes\n- The \"Package Details\" page will offer more actions when a package is opened.\n- The filters is now fully closable, with a new toggle button located on the left side of the search bar\n- The LanguageEngine is more resilient to string deletion on the updated language files.\n- Automated package reload in the installed packages page is now less agressive. It will not remove the packages, only add any missing ones\n- Improvements to the Package Bundles page:\n    - UniGetUI now supports the .ubundle extension, which will ease the process of opening package bundles. The file is internally JSON.\n    - UniGetUI will complain if a bundle fails to be created.\n    - UniGetUI will complain if an unsaved bundle is going to be lost. (The user wants to create a new one, etc)\n    - UniGetUI will warn you if you are overriding a file\n    - Improved handling of InstallationOptions\n    - Bundles will show the version set to install, or the text \"Latest\". It used to show the version with which a package was exported.\n- Optimize how packages are loaded when shared from the \"Share package\" website.\n- UniGetUI can now be interacted with using the unigetui:// protocol. More details here: \n- Other improvements and bug fixes\nSHA256: 27B4E938560BACC58CBD5DE4878EE7033AABA023F53226BAC4FDE0315E7DE793"
