I’ve tried to check if there were updates on the published EoL date for enterprise (paying) customers for UCS 4.4. As of writing the published date in the Univention wiki still says “at least until Nov 01, 2020” (https://wiki.univention.de/index.php/Maintenance_Cycle_for_UCS)
Considering what is cooking up in 5.0, I expect some rather big changes in that release. Not everyone will be able to quickly transition to 5.0 considering how the world has change in spring & summer 2020 during COVID-19.
As of writing we are now 5 months before this currently-published “at least” EoL date. Depending on the industry, that’s not a lot anymore. I’d really appreciated an update and clarification on the EoL date of 4.4 on the forums and the wiki page by the Univention staff.
