Support Commitment


Open-Xchange encourages administrators to regularly update to the latest available release. To ensure a stable and up to date environment please note the different versions supported.

Our support commitment depends on the chosen release channel. Currently we offer two channels for Software Subscription customers: Stable and Long-Term-Support (LTS).

StableMajorA major release might contain new features and bug fixes. The current release cadence is four weeks. Support for a major release is also four weeks long and ends with the availability of the next major release, i.e. after First Customer Shipment (FCS).
PatchPatch releases are limited to bug fixes. A patch releases can be requested for the current stable release and limited to Severity 1 and 2. Issues with severity 3 will be fixed within the next two releases.
LTSInitialLong-term-support releases are supposed to be released every two years. The initial LTS release will be based on a carefully chosen stable release and therefore contain all changes (features and bug fixes) since the last LTS. An LTS release will be supported until the next LTS plus one year to give enough time to schedule, test, and rollout the upgrade.
PatchIn the LTS channel, patch releases are also limited to bug fixes. A patch release can be requested for all severities. While severity 1 and 2 will be addressed as soon as possible, issues with severity 3 might be consolidated within the next 6 weeks.

Please note there is currently no LTS release for version 8 yet. It is scheduled for 2024.
