Release highlights of Univention Corporate Server 4.1-3 include an improved App Center with support for migrating applications to dockerized apps (also known as conternized apps), the stabilization of the replication of directory service objects functionality, and support for joining more than 100,000 directory service objects through the Samba-based Active Directory (AD) domain controllers. Furthermore, it appears that the application appliances have been improved again to allow app providers to define their own branding and enable a fast demonstration mode. Additionally, it’s now possible for public testers to evaluate the app in the appliance using pre-defined settings, which fastens the entire testing process.
