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.

Please Note - Additional Information

Product-, Release- and Component Name	Additional Information
File Storage Integrations	OX App Suite has the possibility to let users integrate their cloud storage accounts of 3rd party services with the OX Drive module of the web UI: File Storages. Access to these services is intentionally limited to web UI and will not be part of the OX Drive apps or the existing WebDAV interface.
LinkedIn Integration	Regarding the integration between OX App Suite and LinkedIn, we would like to notify you about an upcoming LinkedIn API change, which is used by the App Suite app server. We were informed by LinkedIn this week that LinkedIn will restrict access to parts of their currently available API for all existing users and partners by May 15th. LinkedIn will only allow access to the full API, if you sign up for the LinkedIn partner program. Read More: Open-Xchange Forum The LinkedIn integration was removed since 7.10.0
Facebook Integration	Facebook has introduced a new API Permission called “read_stream”, which allows clients of their API to retrieve the Facebook stream of a user. This data was used in the OX App Suite Portal widget to give users instant access to their Facebook data without leaving App Suite. The issue with this new API permission is that Facebook only grants it to 3rd party applications which do not run on the following platforms (All platforms where Facebook already is present): Web, TV, iOS, Android, In-Car. Read More: Open-Xchange Forum
T-Online Integration	Regarding the integration between App Suite and the social network T-Online, we would like to notify you about an upcoming T-Online change, which is used by the App Suite app server. As a result of the change from a clickable HTML page to a single-page-javascript application, the Open-Xchange App Suite Integration for T-Online will stop working and removed.

Maintenance expires

Product-, Release- and Component Name	Maintance expires
We would like to notify you that support for the following products will be discontinued from the 31st. March 2019. Open-Xchange Server 6, OX Hosting Edition, OX Server Edition, OX Mobile Web Interface and OX Notifier. Open-Xchange Server 6, OX Hosting Edition and OX Server Edition, was the first generation of scalable email and collaboration software produced by Open-Xchange for hosted environments. Our second-generation product, OX App Suite, launched five years ago in early 2013, and as a consequence we have decided to discontinue support of Open-Xchange Server 6 and end all maintenance activities. Please note: Open-Xchange Server 6 packages will still be available on our software repositories and will work with the middleware version v7.8.4. but we will not provide any support and maintenance activities. Of course, Open-Xchange is going to keep the Open Source software of those products available to the public.	2019-03-31
Up until now Open-Xchange has provided support for installations of OX App Suite 7.10.x on Debian Jessie. OX App Suite v7.10.x requires OpenJDK 8; OpenJDK 8 is a backport on Debian Jessie and Debian Jessie is currently in LTS (Long Term Support). Recently we have found out that the support for this backport in Debian Jessie has now been discontinued. This means that Debian Jessie no longer supports the required OpenJDK 8. Due to the above situation we regrettably have to inform you that support of OX App Suite v7.10.x and any future version on Debian Jessie must be discontinued from the 2019-03-31. Open-Xchange encourages administrators to regularly update to the latest available platform releases. To ensure a stable and up to date environment please note the different versions supported. An overview of the latest supported platform release can be found in the OXpedia at: http://oxpedia.org/wiki/index.php?title=AppSuite:OX_System_Requirements#Linux_Distributions	2019-03-31
As a result of customer feedback, Open-Xchange will extend the active support commitment for OX App Suite v7.8.4 until 2019-12-31. Open-Xchange wants to allow extended upgrade time to OX App Suite v7.10.x for its customers. Please note, after 2019-12-31, Open-Xchange won't provide any new patches for OX App Suite v7.8.4 version.	2019-12-31
