AppSuite:Versioning and Numbering

Versioning and Numbering of Open-Xchange Products

Abbreviations

The Open-Xchange versioning 2015 will be structured in the following way:

<generation>.<major release>.<minor release> Rev<build number>

Abbreviation	Meaning	Comparison
<generation>	The first number is the product generation number. A new generation may contain new architecture, different technology and many more.	OX App Suite 7
<major release>	The second version number (major release) indicates significant program changes in terms of added functionality. Major changes to design and enhancements of APIs are possible. All APIs shall be backward compatible, which means, that mainly new functions can be added. If Open-Xchange releases a new major release this will be an even number, unstable interim releases have odd numbers.	OX App Suite v7.10
<minor release>	The third version number (minor releases) indicates an update with consolidated bug fixes and non-intrusive feature enhancements. APIs and database will not be changed if this can be avoided. All changes must be backward compatible.	OX App Suite v7.10.6
<build number>	The Rev-number (Revision) shows the progress of the development in single steps	OX App Suite v7.10.6-Rev1
Public Patch Release / Patch Release	A Public Patch Release enables Open-Xchange to publish a feature together with a patch. This in turn enables Open-Xchange to react more flexibly to time requests for certain features, thus relieving minor releases and making it possible to shift them. Delivering a feature with a Public Patch Release requires: It can be implemented without far-reaching side effects. This is especially true for features that are implemented as plug-ins. To a limited extend, features affecting a limited sub set of core functionality can be included. Technical pragmatism is fine to reach the goal (e.g., copy & paste of functionality instead of abstraction into a service). This pragmatism has to be leveled out though as soon as the feature is ported into a more flexible branch. It can be deactivated and is deactivated by default. If a customer installs a Public Patch Release, the familiar feature set does not change. Only if explicitly activating the enhanced features, will they be available to the end user. If features require changes to the data base schema or configuration files, they have to be developed in such a way that they do not impair the running system. Side-effects of Public Patch Releases are evaluated by the respective developers. Together with the QA team, they make a test plan for checking for those side effects and other effects.

As previously announced, in April 2023, Open-Xchange discontinued support for the OX Mail App and the OX Mobile API Facade. In that announcement it was mentioned that users would still be able to continue using the OX Mail App as long as the OX Mobile API Facade remained running. As of the end of July 2024 this will no longer be the case because the OX Mobile API Facade will be completely removed from the software stack. The reason for removing the OX Mobile API Facade is that after Google shutdown Google Cloud Messaging (GCM), and their move to Firebase Cloud Messaging (FCM), Push Notifications for OX Mail App also stopped. As Push Notifications are a vital part of the OX Mail App, Open-Xchange made the decision to remove the OX Mobile API Facade completely from the software stack in the next Public Patch at the end of July 2024.

Open-Xchange rolled out HTTP Strict Transport Security (HSTS) for its web services at open-xchange.com on 2023-06-01. This mechanism will further improve the security of connections and mitigates potential downgrade attacks. It enforces that HTTP clients use HTTPS rather than the unencrypted and unauthenticated version of this protocol. We further intend to use HSTS-preloading, which means clients will use HTTPS straight away and will not attempt to use HTTP.	2023-06-01
Open-Xchange introduced the new OX Drive app v3 for Apple iOS beginning of 2022. This new OX Drive app for Apple iOS, now called "OX Drive by Open-Xchange", is an intelligent file synchronization app for iOS phones and tablets. With this new generation app, Open-Xchange provides a seamless integration into Apple’s app ecosystem and into the system’s own file browser, the Files app. This new OX Drive app replaced the previous OX Drive app v2. We would like to notify you that support for the OX Drive app v2 for Apple iOS will be discontinued from the 3rd of April. With this date, Open-Xchange will remove the app from the Apple App Store. Existing users can continue to use the app but no new users will be able to download it. At the same time Open-Xchange will also stop providing further updates and support it. The new OX Drive app is available at https://apps.apple.com/de/app/ox-drive-by-open-xchange/id1585939206. Existing users of the legacy app can also easily upgrade to the new version by following the "New app available" entry in the navigation panel.	2023-04-03
We would like to notify you that the OX Mail App for iOS and Android will be discontinued on the 3rd of April. With this date, Open-Xchange will remove the apps from the stores.
