The OME team is pleased to announce the release of OMERO.web 5.33.3
On October 28, we released OMERO.web 5.33.3, which includes a bug fix for annotations without namespace and a fix for a security vulnerability, see GHSA-pc58-q9c8-wh7j for more details.
Please see the OMERO.web release and notes on upgrading.
OMERO.web 5.33.3 is available from PyPI - see here.
Following the security incident affecting eMudhra intermediate certificates,
we strongly recommend to upgrade the versions of pip and certifi in the virtual environment running
OMERO.web before upgrading omero-web. Please refer to this
post on the Python forum
for specific instructions on how to upgrade these packages safely.
Official Docker images are available as usual on Docker Hub with either the latest or the 5.33.3 tag:
Please note that the Docker images are now based on Rocky Linux 9 to support the latest OMERO.web releases.
You are invited to discuss this announcement on the image.sc forum.
All the best with your upgrades,
The OME Team
