+* Directories may now be configured with case-insensitive or normalized
+ directory entry names.
+* Modifying the FS setting variable ``max_mds`` when a cluster is unhealthy
+ now requires users to pass the confirmation flag (``--yes-i-really-mean-it``).
+* ``EOPNOTSUPP`` (Operation not supported) is now returned by the CephFS FUSE
+ client for ``fallocate`` for the default case (i.e. ``mode == 0``).

+* Support has been added for NVMe/TCP gateway groups and multiple
+ namespaces, multi-cluster management, OAuth 2.0 integration, and enhanced
+ RGW/SMB features including multi-site automation, tiering, policies,
+ lifecycles, notifications, and granular replication.

Integrated SMB support
* Ceph clusters now offer an SMB Manager module that works like the existing
automatically deployed to improve scalability and memory usage when connecting
Samba to CephFS.

+* Users now have the ability to force-disable always-on modules.
+* The ``restful`` and ``zabbix`` modules (deprecated since 2020) have been
+ officially removed.

RADOS
* FastEC: Long-anticipated performance and space amplification
* OMAP: All components have been switched to the faster OMAP iteration
interface, which improves RGW bucket listing and scrub operations.

+Crimson / SeaStore
+------------------
+
+The Crimson project continues to progress, with the Squid release marking the
+first technical preview available for Crimson.
+The Tentacle release introduces a host of improvements and new functionalities
+that enhance the robustness, performance, and usability
+of both Crimson-OSD and the SeaStore object store.
+In this release, SeaStore can now be deployed alongside the Crimson-OSD!
+Early testing and experimentation are highly encouraged and we’d greatly
+appreciate any initial feedback rounds from the community to help guide future
+improvements.
+Check out the Crimson project updates blog post for Tentacle
+where we highlight some of the work included in the latest release, moving us
+closer to fully replacing the existing Classical OSD in the future:
