Univention Corporate Server 4.1-3 发布，该版本拥有多项针对OpenSSL，QEMU 和 Samba 重要的安全补丁，同时还提供了一些新的特点。
- The App Center has been improved in several areas and further possibilities for the migration of apps to “dockerized” apps have been implemented.
- The replication of directory service objects has been stabilized in numerous corner cases.
- The domain join of additional Samba based Active Directory domain controllers is now possible with more than 100,000 directory service objects.
