Offensive Security released Kali Linux 2021.4, which comes with a number of improvements:

The summary of the changelog since the 2021.3 release from September 2021 is:

  • Improved Apple M1 support
  • Wide compatibility for Samba
  • Switching package manager mirrors
  • Kaboxer theming
  • Updates to Xfce, GNOME and KDE
  • Raspberry Pi Zero 2 W + USBArmory MkII ARM images
  • More tools

Samba Client, Kaboxer theme support

Starting Kali Linux 2021.4, the Samba client is now configured for Wide Compatibility so that it can connect to pretty much every Samba server out there, regardless of the version of the protocol in use. This change should make it easier to discover vulnerable Samba servers “out of the box”, without having to configure Kali.

With the latest update of Kaboxer tools no longer look out of place, as it brings support for window themes and icon themes. This allows the program to properly integrate with the rest of the desktop and avoids the usage of ugly fallback themes.

Here is a comparison of how zenmap looks with the default Kali Dark theme, compared to the old appearance:
