Versioning and Numbering of Open-Xchange Products

General Declaration

The Open-Xchange GmbH currently release two different generations of the Open-Xchange Collaboration Suite.

Open-Xchange Server 5 has been released as a community edition that uses the version namespace 0.8.x which is published in regular cycles as a source-only release. It is the groundwork for the commercial Open-Xchange Server 5 product line. Commercial products use build numbers starting at "5000". Outlook connectors for this version use build numbers starting at 4.0. Open-Xchange Server 5 is no longer sold, and system maintenance stopped on April 30, 2010.

Open-Xchange Server 6 has been initially published in February 2007 and its sourcecode is distributed via a daily synchronized CVS repository and precompiled packages to the Open-Source community. It is the groundwork for the commercial products Open-Xchange Advanced Server Edition (powered by Univention), Open-Xchange Hosting Edition and Open-Xchange Server Edition. Version numbers for all releases of the server and client/connector software are all starting with a "6".

Open-Xchange Server 6 is the successor of Open-Xchange Server 5.

Those two software generations differ extremely from each other, they use different backends, different APIs, different code and different user interfaces. They have in common that they are maintained by Open-Xchange GmbH and are at steady improvement by Open-Xchange and the Open-Source community. Those two generations as well as the connectors are not compatible to each other as of different backend technology and data formats. Open-Xchange offers a wide array of client and synchronization software for popular PIM client software like Outlook. There is also a connector for synchronization between Open-Xchange Server 6 and MacOS X native applications, a web interface optimized for mobile devices and several solutions for mobile device synchronization. Partners and the community are working on synchronization solutions for popular platforms like Evolution or Mozilla Thunderbird/Lightning.

Abbreviations

The Open-Xchange versioning 2009 (After SP5 Update 1) 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 6
<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. 6.10
<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. 6.10.1
<build number> The Rev-number (Revision) shows the progress of the development in single steps 6.10.1-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.
