2. Changelog#

2.1. Released on Apr 28, 2026#

Source package ucs-school-import in version 20.0.0:

Use the new map/unmap functions in the ucsschool_purge_timestamp.py. The updated hook will be used automatically on UCS systems running version 5.2-6 and above, while the previous hook will be used on older systems for backward compatibility. Once you upgrade every UCS system in the domain to at least version 5.2-5 errata 416, you can activate the updated hook early by running the following commands: udm settings/udm_hook modify --set ucsversionend=5.2-4 --dn "cn=ucsschool_purge_timestamp_525,cn=udm_hook,cn=univention,$(ucr get ldap/base)" && udm settings/udm_hook modify --set ucsversionstart=5.2-5 --dn "cn=ucsschool_purge_timestamp,cn=udm_hook,cn=univention,$(ucr get ldap/base)" This will fix issues in UMC in combination with delegated administration (Bug #59216).
