Version requirements

Summary of changes for OMERO 5.6

We aim to support OMERO on the environments specified below, based on the availability of support by upstream developers and operating system distributions. This applies over the lifetime of the 5.6 release and includes security support. Support is limited to those environments on which OMERO is routinely tested.

This page details the minimum version requirements for the current (5.6) release.

It is intended to provide a roadmap in order that sysadmins may plan ahead and ensure that prerequisites are in place for future upgrades.

RHEL 9/Rocky Linux 9 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.

Only the LTS releases are supported due to resource limitations upon CI and testing. Only the last LTS release is supported. There is currently no CI testing for any version.

Microsoft Windows

Client support only. See blog post explanation

MacOS X

MacOS X is typically suited only to client use, not serious server deployment, although the server can be expected to run on versions with current security support for testing purposes.

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.
