The OME project is pleased to announce the release of OMERO and Bio-Formats 4.4.7.

Today we are launching 4.4.7, including several new features and bug fixes across all components.

For OMERO, this includes:

* usability and performance improvements in viewing of 'Big' tiled images;
* new permission features - import data and assign to another user ('Import As'), view all data from all users in a group at once;
* OMERO.web support for 'Split View Figure' and 'Thumbnail Figure' creation;
* OMERO.web support for copy-and-paste of rendering settings;
* addition of several utility functions in the OMERO.matlab toolbox to load and manipulate objects from the server;
* review and testing of the C++ bindings;
* improved checksum calculation to detect errors on file upload;
* and the addition of array columns in OMERO.tables.

Bio-Formats improvements include fixes for the following formats:

* Amira - read files over 4 GiB;
* APNG - remove dependency upon Java ImageIO;
* Bio-Rad Gel - improve pixel offset calculation;
* CellSens - prevent tag parsing errors;
* Deltavision - allow reading of truncated files, fix errors when importing into OMERO;
* FITS - support truncated files;
* FV1000 - cope with missing thumbnails;
* Gatan - improve metadata parsing;
* Imaris HDF - correct channel count;
* Leica LIF - supported tiled images and parse User-Comment tags;
* Metamorph - correct channel count;
* Micromanager - correct file finding for single-channel datasets;
* Nikon ND2 - many improvements to metadata parsing
* SimplePCI - improve Z and T dimension calculation;
* Olympus SIS TIFF - read pixel sizes and exposure;
* Olympus ScanR - correct well linkage;
* TIFF - various fixes for reading tiled images
* Trestle - improve support for sub-resolutions;
* Zeiss CZI - parse Z positions, parse linescans, fix ordering of stitched files;
* Zeiss LSM and Zeiss ZVI - improve ROI parsing;
* improve export to multi-file datasets;
* and Bio-Formats now uses slf4j for logging rather than using log4j directly, enabling other logging implementations to be used, for example when Bio-Formats is used as a component in other software using a different logging system.

Full details are available on the OMERO Github milestone and the Bio-Formats Github milestone pages:

As always, the software is available from and

If your Fiji is up to date, your version (seen via Help > About Plugins > LOCI Plugins) should say "4.5-DEV".

Currently, Fiji provides builds from the 4.5.x "development" line (develop branch of the Git repository), rather than from the 4.4.x "stable" line (dev_4_4 branch).

For details, see:

All bugfixes in the 4.4.x stable line should also be part of the 4.5.x development line. If there is a recent bugfix you need that has not yet been pushed to Fiji, let us know and I can upload a new version of 4.5.x.
