We contentedly announce the release of: cinder 25.2.0 This release is part of the dalmatian release series. The source is available from: https://opendev.org/openstack/cinder Download the package from: https://tarballs.openstack.org/cinder/ Please report issues through: https://bugs.launchpad.net/cinder/+bugs For more details, please see below. 25.2.0 ^^^^^^ New Features ************ * Ceph driver: Add config option to keep only the last n snapshots per backup to save disk space on the source volume storage. Enabling this option can cause incremental backups to become full backups instead under special circumstances. Please take a look at the Ceph backup driver docs for more information. Bug Fixes ********* * Dell PowerMax Driver bug #2081742 (https://bugs.launchpad.net/cinder/+bug/2081742): The REST API calls for the masking view connection do not return the HostLUN ID immediately. To address this, an exception has been added to implement a retry mechanism. * Dell PowerMax Driver bug #2092259 (https://bugs.launchpad.net/cinder/+bug/2092259): Before a volume can be deleted, the driver issues a command to clean up active snapshots in the backend and then polls the backend to make sure the cleanup has occurred. This fix enhances the polling mechanism to give the backend more time to do the cleanup, thereby increasing the probability that the driver will be able to make a successful volume deletion request. * NFS driver bug #2074377 (https://bugs.launchpad.net/cinder/+bug/2074377): Fixed regression caused by change I65857288b797 (the mitigation for CVE-2024-32498) that was preventing the creation of a new volume from the second and subsequent snapshots of an existing volume. * RBD driver bug #2092534 (https://bugs.launchpad.net/cinder/+bug/2092534): Fixed uploading a volume to image when image has different format than volume.
