         - upgrade checking now considers modification dates as well (needed because not all AUR packages follow versioning standards)
         - downgrade: using the cached package commit (if available) to determine the correct version to downgrade to (otherwise only the version will be used -> old behavior)
         - history: using the cached package commit (if available) to properly determine the current version (otherwise only the version will be used -> old behavior)
