OME-Zarr

Support for OME-Zarr labels and images in OMERO Plus has been improved to handle:

  • images and labels stored as Zarr arrays with 2, 3 and 4 dimensions, e.g. as produced by bioformats2raw 0.11.0 with the --compact option
  • images and labels hosted on S3-compatible object storage, not just AWS’s S3. This has been validated against public Ceph and Google Cloud Storage buckets.
  • images and labels hosted on public S3-compatible object storage (private buckets are also supported)
  • images and labels with missing chunks hosted on object storage

Glencoe’s OME-Zarr importer has also been updated to support new anonymous import of OME-Zarr images on public S3 buckets and OME-Zarr images hosted on S3 compatible object storage.

Security & maintenance improvements

Several server environments are hardened to mount the /tmp partition with noexec permissions, e.g. as recommended by the CIS benchmarks of the NIST SP 800-53 framework. The OMERO server and micro-services as well as OMERO import clients have been updated to work natively in these environments. This change has been made for both open source OMERO and OMERO Plus components.

OMERO.web now supports the latest Django LTS version 5.2 and includes a fix for a security advisory
