The OME Consortium published an update on the status of Bio-Formats 6 and the OME-TIFF pyramidal format - see https://blog.openmicroscopy.org/file-formats/community/2018/11/29/ometiffpyramid/ for more information.
We plan to release several more milestones leading up to Bio-Formats 6 over the next few months. For the Fiji community, we are planning to start distributing these milestone releases via the Bio-Formats development update site soon. We will publish announcements in this forum when this happens.
