What's new for OMERO 5.3 for sysadmins ====================================== - Ice 3.6 is now the default supported version. With Ice 3.6, the Python bindings are provided separately, allowing you to install the RPM packages provided by ZeroC. Then run ``pip install zeroc-ice`` to install the Ice Python bindings if your package manager does not provide the Ice Python packages. - :doc:`version-requirements` has been updated to reflect other changes in version support for 5.3.0 and tentative plans for 5.4.0. - All official OMERO.web apps can now be installed from PyPI. You should reinstall your plugins when you upgrade. - Windows support has been discontinued, see :doc:`/sysadmins/windows-migration`. - OMERO.web has been decoupled from the server and can now be deployed separately. It now requires Python 2.7 meaning systems still running on CentOS 6 may require upgrading. - Support for deploying OMERO.web using Apache has been dropped; if your organization’s policies only allow Apache to be used as the external-facing web-server you should configure Apache to proxy connections to an Nginx instance running on your OMERO server i.e. use Apache as a reverse proxy. - jQuery cache is now disabled by default. - A new script is available to allow users to migrate annotations from Images to Wells which you may wish to run server-side when upgrading. These annotations will be reindexed automatically so your users can search Wells by annotations in the new GUI for Screen Plate Well data. - New options have been added for customizing the tree in the clients, see :ref:`client configuration properties `. - The default output when importing data via the |CLI| has been updated to give an Image or Plate ID list in the form of ``Image:1,2,3,4`` or ``Plate:101`` to be more usable by scripts etc. The previous behavior can be restored by using ``--output legacy``.
