     - The optimized **makepkg.conf** file is now generated at **~/.config/bauh/arch/makepkg.conf** and passed as a parameter during package builds to not provoke the auto-merge of **/etc/makepkg.conf** and the old generated **~/.makepkg.conf**.
     (P.S: if your **~/.makepkg.conf** was generated by bauh, consider deleting it as it will be useless for bauh now and may impact your other Arch compilation tools). Behavior discussed in [#30](https://github.com/vinifmor/bauh/issues/30).
+    - Now AUR packages are enabled by default, but a warning is displayed in the installation dialog
