Version requirements

Summary of changes for OMERO 5.3 and provisional changes for 5.4

Criteria for what is considered to be supportable includes whether support by both upstream developers and operating system distributions will be available for the lifetime of the 5.3 release (including security support), and also upon our resources allocated to CI and testing. If we are not actively testing it, we cannot claim it is supported or functional. Software components must be provided and supported either by an operating system distribution or their original developers.

This section contains a summary of the changes made to the minimum version requirements for the 5.3 release and also possible changes for the following 5.4 release, albeit tentatively at this point. The intent is to provide a roadmap in order that sysadmins may plan ahead and ensure that prerequisites are in place ahead of time to ease future upgrades. The following sections provide more detailed information and the rationale for the changes.

Please check the meaning of the various symbols used on this page. Any system/component with a green tick symbol is supported.

Operating systems

  • Microsoft Windows

  • MacOS X

    • MacOS X is typically suited only to client use, not serious server deployment, although the server can be expected to build on versions with current security support for development purposes.
  • Linux (CentOS/RHEL)

    Linux version OMERO 5.3 OMERO 5.4
    6.x Deprecated Dropped
    7.x Recommended Recommended
  • Linux (Ubuntu LTS)

    Linux version OMERO 5.3 OMERO 5.4
    12.04 Dropped Dropped
    14.04 Supported Supported
    16.04 Recommended Recommended
    • Only LTS versions are supported and tested. Non-LTS versions following a supported LTS release are likely to work but are not officially supported or tested.
    • Rationale: No change in this timeframe.

Bitness

Currently both client and server will work on 32- and 64-bit systems on all platforms with the exception of MacOS X (64-bit only).

Bitness OMERO 5.3 OMERO 5.4
32-bit Deprecated for Ice and native code [client] Dropped for Ice and native code [client]
64-bit Recommended Recommended

Components

  • PostgreSQL

    PostgreSQL OMERO 5.3 OMERO 5.4
    9.2 Dropped Dropped
    9.3 Deprecated Dropped
    9.4 Supported Deprecated
    9.5 Supported Supported
    9.6 Recommended Recommended
    • Rationale: Current releases available for all supported systems from upstream and for CentOS/RHEL 6.x officially via SCL (software collections).
  • Python

    Python OMERO.web 5.3 OMERO.server 5.3 OMERO 5.4
    2.6 Broken Supported Dropped
    2.7 Recommended Recommended Recommended
    3.x Broken Broken Broken
    • Rationale: 2.7 is provided by all systems except for CentOS/RHEL 6.x, however it is available officially via SCL. Note that 3.3 is also available via SCL, so there is potential for a 3.x migration in the 5.3 timeframe. OMERO.web no longer works with Python 2.6, the OMERO.server can still be used with Python 2.6.
  • Ice

    Ice OMERO 5.3 OMERO 5.4
    3.4 Dropped Dropped
    3.5 Deprecated Dropped
    3.6 Recommended Supported
    3.7 Upcoming Upcoming
  • Java

    Java OMERO 5.3 OMERO 5.4
    7 Deprecated Deprecated
    8 Recommended Supported
    9 Upcoming Recommended
    • Rationale: For 5.3 deprecate 7; this is because security support ended in April 2015. Currently, Matlab is shipped with Java 7 so it cannot be marked as dropped yet.
  • nginx

    nginx OMERO 5.3 OMERO 5.4
    1.4 Dropped Dropped
    1.6 Supported Supported
    1.8 Supported Supported
    1.10 Recommended Recommended

Support levels

The following table defines the symbols used throughout this page to describe the support status of a given component, as it progresses from being new and not supported, to supported and tested on a routine basis, and to finally being old and no longer supported nor tested.

Level Meaning Description
Upcoming unsupported/new New version not yet regularly tested and not officially supported; may or may not work (use at own risk)
Supported supported/suboptimal Version which is tested, confirmed to work correctly, but may not offer optimal performance/experience
Recommended supported/optimal Version which is regularly tested, confirmed to work correctly, recommended for optimal performance/experience
Deprecated supported/deprecated Version which is less tested, expected to work correctly, but may not offer optimal performance/experience; official support may be dropped in the next major OMERO release
Dropped unsupported/old Old version no longer tested and no longer officially supported; may or may not work (use at own risk)
Broken unsupported/broken Known to not work
Unsupported unsupported/misc Not supported for some reason other than the above

Operating system support

The following subsections detail the versions of each operating system which are supported by both its upstream developers (for security and general updates) and by OME for OMERO building and server deployment.

UNIX (FreeBSD)

It only really makes sense to support the base toolchain for major releases and the Ports tree (which is continually updated); these will be covered in the dependencies, below.

Linux (CentOS and RHEL)

General overview for RHEL and CentOS

Version Release date Upstream support OMERO 5.2 OMERO 5.3 OMERO 5.4 Details
6 from Nov 2010 to Nov 2020 Supported Deprecated Dropped Reference
7 from June 2014 to June 2024 Recommended Recommended Recommended Reference

RHEL, CentOS 6 and 7 are supported at present. Given the long life of enterprise releases, we intend to support only the latest release at any given time or else it ties us into very old dependencies; 6.x is already quite long in the tooth, however is in wide use and so will require supporting at least 5.3.0.

Linux (Ubuntu)

General overview

Version Release date Upstream support OMERO 5.2 OMERO 5.3 OMERO 5.4
14.04 LTS from Apr 2014 to Apr 2019 Recommended Supported Supported
16.04 LTS from Apr 2016 to Apr 2021 Recommended Recommended Recommended

Only the LTS releases are supported due to resource limitations upon CI and testing. Only the last two LTS releases are supported (being a bit more frequent than CentOS/RHEL). There is currently no CI testing for any version, but some developer use of 14.04 LTS, 16.04 LTS and more recent non-LTS releases.

Dependencies

The following subsections detail the versions of each dependency needed by OMERO which are supported by both its upstream developers (for security and general updates) and by OME for OMERO building and server and client deployment.

Note

Versions in brackets are in development distributions and may change without notice.

At the moment 2.7 support is present upstream for the foreseeable future; 3.x versions continue to be released and retired regularly in parallel. The limiting factor will be distribution support for 2.7 as major packages are slowly switching to 3.x, and this might cause problems if our python module dependencies are no longer available without major effort.

The supported version of the Django module used by OMERO.web (1.8) requires Python 2.7. The older version (1.6) will work with Python 2.6 but lacks security support, and is consequently not recommended for production use.
