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 v7.6
<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 v7.6.1
<build number>	The Rev-number (Revision) shows the progress of the development in single steps	OX App Suite v7.6.1-Rev3
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.

Open-Xchange will roll 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. While this does not have any negative impact in general, we like to raise awareness for potential edge-cases that require your attention, if you are using our software repositories at https://software.open-xchange.com/. This service will also use HSTS, and we identified potential connectivity issues in case the repository lists or mirrors on your end refer to plain HTTP. We have already updated the documentation to use HTTPS exclusively, but there may be cases where environments have been set up before that. Please verify that all references to our software repositories, your egress network filtering and package managers are enabled to use HTTPS. - For DEB based environments, make sure that the apt-transport-https package is installed and all URLs at /etc/apt/sources.list and /etc/apt/sources.list.d/ use the HTTPS URL scheme - For RPM based environments, make sure that all URLs at /etc/yum.repos.d/ use the HTTPS URL scheme
