 ### Fixes
 - AppImage
   - some desktop entries not being displayed on the desktop environment menu (requires the AppImage to be reinstalled) [#287](https://github.com/vinifmor/bauh/issues/287)
+- Arch
+  - not detecting some package replacements when upgrading due to conflict information having logic operators (e.g: `at-spi2-core: 2.44.1 -> 2.46.0` should replace the installed `at-spi2-atk: 2.38`)
 - GUI
   - management panel not fully maximizing
