The latest patch level release UCS 3.2-3 includes all errata updates and an update to Linux kernel version 3.10.11 which involves many bug fixes and improves the hardware support.
Special highlight is the new module "Active Directory Connection", which replaces the previous AD connector for mounting a UCS installation in an AD domain. UCS users can now not only migrate an existing Microsoft server system to UCS but also configure their UCS system as part of an existing AD domain, for example to use UCS as the platform for applications from independent third-party solutions via the Univention App Center. Further highlights are a completely revised system setup wizard, a backport of PHP 5.4.4 and improved replication between OpenLDAP and Samba 4.
