Dear All,

Today we are launching 4.4.9, a bug-fix release addressing a number of issues across all components.

For OMERO, this includes:

* fixing compatibility issues between clients and servers using different Ice versions e.g. client using Ice 3.5 connecting to a server using Ice 3.4;
* adding Ice 3.5 support;
* updating minimum system requirements to Java 1.6 (Java 1.5 is no longer supported);
* a major reworking of the testing infrastructure;
* new scripting sharing service as requested by users [1];
* new user help website to host workflow-based guides [2];
* new partner project pages to highlight work going on within the extended OME consortium.[3]

A security vulnerability [4] has also been identified and resolved, meaning that we strongly recommend all users upgrade their OMERO clients and servers. Sysadmin documentation for upgrading your server is at

Bio-Formats improvements include a number of bug fixes including for the ND2 format.

Full details are available on the OMERO Github milestone [5] and the Bio-Formats Github milestone [6] pages.

The software is available from

This move to<> is to facilitate all versions of the software being available from one location - legacy versions will be available here soon.

Kind regards,
The OME team
