Derived from the freely distributed sources of Red Hat Enterprise Linux, BaruwaOS 6.9 is based on Red Hat Enterprise Linux 6.9, which is the last stability and bugfix release of the Red Hat Enterprise Linux 6.x operating systems series. Therefore, BaruwaOS 6.9 should also be the last maintenance update for its 6.x series. Besides all the security updates inherited from Red Hat Enterprise Linux 6.9, BaruwaOS 6.9 gains many new features and improvements, among which we can mention support for disabling SMTP TIME rejections and the DANE protocol, better Sophos and F-Prot integration, as well as improved brute force protection.
