Release process

This document explains the release process of eZ Platform and eZ Studio projects.

eZ Platform is an open-source software developed by eZ together with the eZ community whose code base is available on GitHubeZ Studio is proprietary (commercial) software. Both projects are following the eZ Enterprise release process described below.

eZ manages its release using an agile iterative process and a continuous software development model.

eZ releases are of two kinds:

  • eZ Long Term Supported releases (LT) which are supported by eZ for a long period of time (see below support lifecycle), for eZ Enterprise subscribers.
  • eZ Fast Track releases (FT) which are supported for a short period of time, until a new FT release is introduced. These are supported for both Community and eZ Enterprise subscribers.


Support life cycle

Our software products are continuously evolving, and we have released many versions over the years.

We strive to release stable products with cutting-edge technology. However, with new software, there is the inevitable need for Software Maintenance services to provide bug fixes and adjustments for evolving web technologies.

And as our products always provide new features and possibilities, our documentation and user forums may not always be able to provide an answer to all questions that may arise, in which case our Product Support service team stands ready to assist.

Over time, existing product versions mature and new versions become the center of attention for customers wanting the latest and greatest in features and extensibility. We adapt to this continuous evolution by phasing out services for the old versions while commencing services for the new ones.

This means that our services specific to each release are only available from a given start date until an end date. The time in between the start and end dates is what we call the product's Service Life.

This table provides an overview of the beginning and end of the Service Life of our products*.

Releases preceding eZ Publish 4.4 have all reached their EOSL and their SLE.

  • FSM: The First Ship Month we accept installations to start using this version.
  • LSM: The Last Ship Month we accept installations to start using this version.
  • EOSL: End Of (normal) Service Life, the last month we provide Product Support and Software Maintenance services for a given version.
  • SLE: Extended Software Maintenance which includes security updates beyond EOSL. Contact your sales representative for more details.
    • Note: SLE is a "best effort" product with no bug fix guarantee. Hence, under SLE it is not recommended to do new development like redesign, moving to new servers, new server operating system or similar. For such efforts, please upgrade to a version within normal service life first.
  • LTS: Long term supported release

* For individually agreed lengths of Service Life, please consult your contract. If it goes beyond EOSL it will effectively be valid under the terms of SLE.
** 5.0 was changed to a short term release for new customers when 5.1 came out, thus new contracts have an EOSL in November 2013. We recommend that all existing 5.0 customers upgrade to an LTS release.
*** 5.4 introduces new features in "6.0/Platform stack" and will continue to get certain new features during 2015 to ease forward compatibility with eZ Platform and eZ Studio. For further information see 5.4 release notes.
**** 5.4 being the last eZ Publish release, it will be available for existing eZ Publish customer beyond Last Ship Month (until EOSL), and have an extended service life, making it an ideal release for slow migration to eZ Platform and eZ Studio.


eZ roadmap is updated continuously following our iterative development methodology (an adaptation and combination of Scrum and Kanban that we continuously adapt). Our agile board is open so that anyone can have a clear view of the ongoing and upcoming development. Progress is based on the prioritized Epics from a living backlog into phases of specification and design, development and documentation, and QA. The final phase of our development includes a dedicated period of Certification and Quality Assurance, which ensures our ability to deliver a stable first version of the professionally supported software.

If you want to know what are the EPICS (big features) we are working on, please look at our dedicated product development board:

How to read?

The Epic board can at first be daunting to understand, so here are some things to be aware of:

  • Doc: Means the feature has most likely either been developed already in the last release, or will be in the next one, but might still be missing some documentation.
  • Dev: Features in progress, unless just started, they will be part of the next upcoming release (barring some roadblocks).
  • Prioritized/Spec: These are the next features we will start working on, prioritization and main responsibility to specify is done by eZ Product Management team.
  • Open: A backlog of features we want to have in place in the future.

Work currently in progress

The following list represents the Epics currently in progress and which might make it in the next release.

Our process being open, please feel free to report bugs or suggest features via our JIRA projects: the EZP Jira project for all things related to eZ Platform, and the EZS Jira project for all things related to eZ Studio.

If you'd like to help speed things up because you need a feature on a project, Epics in Open state is relatively safe to jump on. 

  1. Simply add a comment on the one you have already worked on or would like to start on among the epics on the board, and folks at eZ will try to help on specifying the feature.
  2. For discussions on how to tackle the feature technically, or anything else, reach out on Slack using the self service sign on page.
  3. When a Pull request has been opened, most of the discussion will happen in the relevant github repositories.
  4. When a feature is done, you can help out on documentation by proposing documentation using for instance and link to them via comments on the Epics.
