Logo Enterprise Samba

The Samba Team at SerNet just released Enterprise Samba 4.1.18 and 4.0.26. This is the last bug-fix release of the Samba 4.0 release series. From now on there will be only security releases. Samba 4.1 will be continued in the maintenance mode; Samba 4.2 is the current stable release series - therefore the Enterprise Samba packages enter the security fixes only mode, too.

The current packages are available for various SUSE and RedHat platforms as well as for Debian GNU/Linux and Ubuntu:

These packages address a lot of issues listed in the Samba history (for 4.1, for 4.0). For more information about the Samba release system visit the Samba Wiki.
