4.4.8 (May 2013)

This is bug-fix release addressing two specific issues: a problem with the OMERO.insight client for Linux, and image thumbnails not loading for Screens/Plates in Private/Read-Only groups in OMERO.web. You only need to upgrade if you are an OMERO.insight user on Linux or you are using OMERO.web to view HCS data in Private or Read-Only groups.

4.4.7 (April 2013)

This is a point release including several new features and fixes across all components. This includes improvements in viewing of ‘Big’ tiled images, new permission features, new OMERO.web features, and several utility functions in OMERO.matlab.

4.4.6 (February 2013)

This is bug-fix release addressing a number of issues across all components. This includes a major fix to repair the C++ binding support for Ice 3.4. There has also been a potentially breaking update to the CLI.

4.4.5 (November 2012)

This is bug-fix release focusing on improvements to the OMERO clients. OMERO.web now supports “batch de-annotation”, filtering of images by name and improved export to OME-TIFF and JPEG. OMERO.insight has fixes to thumbnail selection and image importing and exporting.

4.4.4 (September 2012)

This is a bug-fix release addressing a number of issues across all components.

  • OMERO.insight fixes include connection and configuration options and tagging on import.

4.4.3 (August 2012)

This is a critical security fix for:

Anyone using OMERO 4.4.2 or earlier with LDAP authentication should immediately upgrade to 4.4.3.

4.4.2 (August 2012)

This release is a major bug fix for archiving files larger than 2 GB. If you do not archive files larger than 2 GB, you do not need to upgrade your clients or your server. There is also a minor fix for an OMERO.imagej plugin security issue, but it is only necessary to update the version of Bio-Formats that is installed in ImageJ.

4.4.1 (July 2012)

This is a minor release which fixes two import issues. See #9372 and #9377. If you are not using BigTIFF or PerkinElmer .flex files, then you do not need to upgrade.

4.4.0 (July 2012)

This is a major release, which focuses on providing new functionality for controlling access to data, as well as significant improvements in our client applications.

The major theme of 4.4.0 is what we refer to as “Permissions”, the system by which users control access to their data. It is now possible to move data between groups, and much, much more.

We also added a few more things for users in 4.4.0, like:

  • OMERO.insight webstart
  • Importing from OMERO.insight is now complete
  • Better integration of OMERO.insight with ImageJ
  • A bottom-to-top reworking of the OMERO.web design

For developers and sysadmins, there are a few things as well:

  • Support for Ice 3.4
  • Removed support for PostgreSQL 8.3

Beta 4.3.4 (January 2012)

This is a point release is a security update to address an LDAP vulnerability.

Beta 4.3.3 (October 2011)

This point release is a short follow on to 4.3.2 to handle various issues found by users.

Beta 4.3.2 (September 2011)

This is a point release, focusing on fixes for OMERO.web, export, and documentation. A couple of LDAP fixes were also added, following requests from the community. We also included something many of you have asked for some time, OMERO on virtual machines.

Beta 4.3.1 (July 2011)

This point release focuses on fixes for Big Images, OMERO.web and others.

Beta 4.3.0 (June 2011)

This is a major release, focusing on new functionality for large, tiled images, and significant improvements in our client applications.

The major theme of 4.3.0 is what we refer to as “Big Images”, namely images with X,Y images larger that 4k x 4k. With this release, OMERO’s server and Java and web clients support tiling and image pyramids. This means we have the functionality you have probably seen in online map tools, ready for use in any image file format supported by OMERO (and obviously Bio-Formats). This is especially important for digital pathology, and other uses of stitched imaging.

While the major focus of 4.3.0 was Big Images, there are a number of other new updates. For users, we have worked hard to synchronise functionality and appearance across the OMERO clients. This includes viewing of ROIs in OMERO.web. We are not done, but we have made a lot of progress. Moreover, data import is now MUCH faster and available from within OMERO.insight.

Beta 4.2.2 (December 2010)

Fixes blocker reported using 4.2.1. Starting with this milestone, all tickets for the insight client are managed on Trac.

Beta 4.2.1 (November 2010)

This is a point release, focusing on fixes for delete functionality, and significant improvements in the way OMERO.web production server is deployed.

Beta 4.2.0 (July 2010)

This release is a major step for OMERO, enabling a number of critical features for a fully functional data management system:

  • User and Group Permissions and data visibility between users
  • updates to the OME SPW Model and improvements in HCS data visualisation
  • SSL connection between OMERO clients and server;
  • full scripting system, accessible from command line and within OMERO.insight, including Figure Export and FLIM Analysis

Improved support for metadata, especially for confocal microscopy; OMERO supports all of the file formats enabled by Bio-Formats. Export to OME-TIFF and QuickTime/AVI/MPEG from OMERO. Various improvements to OMERO clients to improve workflow and use.

This release introduces - a feedback mechanism, to allow us to communicate more effectively with our community. supports uploading of problematic files, and tracking of responses to any user queries. Moreover, includes a demo feature: in collaboration with Urban Liebel at Karlsruhe Institute of Technology, we are providing demo accounts for OMERO. Use the Demo link at qa to contact us if you are interested in this.

For users who have had problems with memory-based crashes in OMERO.insight, the new OpenGL-based ImageViewer may be of interest. Also, we are now taking advantage of our modeling of HCS data, and releasing our first clients that support Flex, MIAS, and InCell 1000 file formats. OMERO.dropbox has been substantially extended, and now supports all the file formats supported by OMERO.

Beta 3.0 (June 2008)

This release of OMERO is a major update of functionality. In OMERO.server, we have added support for StructuredAnnotations a flexible data management facility that allows essentially any kind of accessory data to be linked to images and experiments stored in OMERO. Alongside this, we provide an indexing engine, that provides a flexible searching facility for essentially any text stored in an installation of OMERO.server. Finally, we are releasing our first examples of clients that use the OMERO.blitz server, a flexible, distributed interface that supports a range of client environments. One very exciting addition is OMERO matlab, a gateway that can be used to access OMERO from Matlab®.

OMERO Beta3.0 includes a substantial reworking of our clients as well. OMERO.insight has been substantially updated, with an updated interface to provide a more natural workflow and support for many different types of annotations, through the StructuredAnnotations facility. The new search facilities are supported with smart user interfaces, with auto-complete, etc. New file formats have been added to OMERO.importer, including support for OME-XML, and an improved import history facility is now available. Finally, Beta3.0 includes the first release of our experimental electronic notebook tool, OMERO.editor. This represents our recent efforts to capture as much metadata around an experiment as possible.

Beta 2.3.3 insight (April 2008)
