In May 2021, the release of UCS 5 took place. Important changes are:
Since the release of UCS 5, installations have been increasing daily. New systems are being installed and existing UCS 4 systems are being updated.

In the Univention App Center you will find a constantly growing number of software solutions from different manufacturers for a variety of use cases, for companies and public institutions. These apps can be easily installed in the App Center, integrated into your own IT and conveniently managed via the central management system of UCS 5. One aim of UCS 5 is to make the integration of apps even easier and more efficient. Apps can be managed and updated completely independently by the providers. The release process continues to go through internal tests and quality assurance processes to ensure functionality as well as quality.
The update of core elements of UCS also made it necessary to check and adapt all apps. With the release, Univention has made the most important of its own apps directly available, and many others have since been adapted to UCS 5 by the app providers and Univention. Apps that are still outstanding will be updated in the coming months.
For example, the following apps have recently been migrated and are available for UCS 5:
The following apps will be updated in the coming weeks or months and will then be available for UCS 5:
In some cases, no porting of the app from UCS 4 to UCS 5 is provided by the app provider The following apps will no longer be available in UCS 5. This does not automatically mean that the software is no longer compatible with UCS 5. In most cases, the apps can be installed and used manually on UCS 5 using paths documented by the manufacturer. We or the manufacturers will inform about this individually.
The journey for UCS continues. Themes that have already been launched will be continued in order to continuously improve UCS. New topics are e.g.:
We will inform about the new planned features at the Univention Summit and subsequently here on the blog.
Univention is fully concentrating its efforts on the further development of UCS 5. New apps and features will only be further developed for UCS 5 with immediate effect. For those for whom an upgrade to UCS 5 is not yet directly possible, Univention offers the Maintenance Lifecycle below. After that, a change to UCS 5 is strongly recommended.
Sep/2022: End of Core Edition Maintenance – users of the free UCS version will no longer receive updates for UCS4 and should therefore upgrade to UCS5 beforehand.
Jan/2023: End of Standard Maintenance. From this date, security updates for UCS 4 will no longer be available for customers with maintenance contracts.
We have also decided that we will no longer update the UEFI Secure Boot signatures that have expired in UCS 4. In current versions of the UEFI BIOS, the signature used by UCS is no longer accepted because it was withdrawn due to potential vulnerabilities in the boot sequences used by UCS 4. However, UCS 4 can still be installed on such hardware in the “legacy” mode of the BIOS.
In the work on updating the signature, which has been ongoing for some time, the release of current signatures by the bodies involved has been halted in principle, as further potential vulnerabilities are being examined. Due to the running times of the release processes, it no longer appears possible to update the signatures in UCS 4 before the end of maintenance. UCS 5 is not affected by these restrictions.
We ask our customers who are still using UCS 4 to take these dates into account and to plan and carry out a migration to UCS 5 in good time. Our support team will be happy to answer any questions you may have about the update. We support our customers and respond to individual needs when migrating to UCS 5.

No UCS 5.0 support for SuiteCRM or OpenProject??
Is there a roadmap from these packages?
Soon there will be little to recommend the Core Edition.
Hello Alan Walters,
We are in clarification regarding SuiteCRM, but it may happen that we will remove the app form the app center. If so, there will be an official communication.
The OpenProject app is ongoing and we hope to release it soon. There are still some test and integration work outstanding. We will give a weekly update on help.hunivention.com.
Are there plans to move to debian 11 in a point release of UCS 5 or have we to wait for UCS 6?Reply
we are planning to switch to Debian 11 with UCS 5.1. However, a release date for this has not been set yet. If you want to know more about the future development of UCS, I recommend the Summit presentation of our colleague Ingo Steuwer. You can find it on our Youtube channel at: https://www.youtube.com/watch?v=aNcXoxvquTU
When will the Zimbra connector be released for 5.0 – I am stuck and can’t update until then. Now Windows 11 22H2 is rendering domain joining an issue 🙁Reply
thank you very much for your question. In this case, Synacor, developer of the Zimbra app, is on the hook. We have asked for an update and will get back to you via our communication channels (social media, help forum, Univention blog) as soon as we know a release date.
