Today we release Orbit version 2.52 (for Omero 5.2.x) and Orbit 2.53 (for Omero 5.3.x).
Both versions are identical except support for different Omero major versions and support multichannel / fluorescence images with unlimited number of channels. In addition, this version provides many bugfixes and speed improvements. Multi series / scenes can be selected in the file open dialog. Gamma/contrast works properly now. Scalebar should work for most filetypes. Makes use of the new Bioformats 5.4.0. Please upgrade now!
