Important - Please Note
  • There is a major Hazelcast library update to OX App Suite v7.8.4. This means that when updating from an earlier backend version, due to the upgraded library, it is not possible to form a cluster of nodes that run previous version of Hazelcast (i.e. exiting volatile data in the cluster will be lost during the update). A consistent Hazelcast cluster is needed for cluster-wide cache invalidation. To circumvent problems with database update tasks that need to perform cache invalidation, please follow the steps described here:
  • Please also note that session migration is not possible between versions. This usually affects all user sessions that are stored in a distributed map, and will require the users to re-login after the update. Running incompatible versions of Hazelcast within a cluster will result in log entries showing the conflicting node and version information.
  • During the upgrade to 7.8.4 the existing JAVA_XTRAOPTS configuration property of the middleware stack in the file will automatically be split up and migrated to a new categories approach. Please review the JVM command line options here: ( and review the automatically upgraded configuration file.
  • In accordance with the supported platform policy, Open-Xchange will discontinue maintenance and support for Connector for Microsoft Outlook, Open-Xchange Updater with the next major release (planned beginning of 2018). Existing customers with Connector for Microsoft Outlook in their portfolio, will receive full maintenance and support until beginning 2018. To support the discontinuation, we are happy to announce that Open-Xchange will provide releases of all native apps including OX Mail App, OX Drive App, eM client for OX App Suite and OX Sync App over the coming months. This has the advantage of providing a similar user experience on all devices, to all clients, and allows us to take a holistic approach to the development of our product portfolio.
  • Please note: to ensure a stable and up to date environment, starting with OX App Suite v7.8.4, Open-Xchange will support Suse Linux Enterprise Server 12 together with OpenJDK 7 instead of IBM Java 7. For details of all supported platforms and databases please refer to the requirements page at:
  • As started with OX App Suite v7.8.3 Open-Xchange deprecates its munin monitoring scripts that are based on parsing the output of command-line tools like 'showruntimestats'. In the past, two versions of every monitoring script have been maintained, one based on such output and the other based on direct HTTP communication with the OX middleware. From OX App Suite v7.8.4, only the HTTP-based versions will be available, using Jolokia ( under the hood. Details regarding Jolokia-based monitoring can be found here: and
