- Many small improvements have been made under the hood:

- Calls to gksu, which is unsafe, are replaced with pkexec.

- The default package list has been adjusted and some useful system tools have been added.

- The former CrunchBang audio mixer, pnmixer, has returned (replacing volts).

- The previously required Pulseaudio configuration settings have been removed.

- Added support for QT5 GTK2 theme.

- The start menu now has a "boot in cli" option and a "Rescue" option.

- Almost all executable programs (scripts, etc.) of BunsenLabs now have simple pages.

- The Compton configuration has been improved and reorganized.

- A file /etc/bunsen/bunsen_installcontains information about the system installation method, version and date to help diagnose.

- Numerous other small changes.
