Tentacle is the 20th stable release of Ceph.
+v20.2.2 Tentacle
+================
+
+This is the second minor release in the Tentacle series. We recommend that all users update to this release.
+
+Release Date
+------------
+
+June 15, 2026
+
+Notable Changes
+---------------
+
+* Rocky 10 is now supported starting with v20.2.2. Please see the `supported platforms <https://docs.ceph.com/en/latest/start/os-recommendations/#platforms>`_ for current and planned support in Ceph.
+
+MDS (Metadata Server)
+---------------------
+
+* Upgrade Testing Architecture: Split up existing upgrade sequences into distinct CentOS Stream 9 and Rocky Linux 10 automated test variants across multiple upgrade suites (including parallel, stress-split, and telemetry suites).
+* Queueing Logic Update: Retry requests are now added directly to the MDSRank wait queue rather than going through the finisher.
+* Optimization: Removed duplicate context completion calls and adjusted scan_stray_dir after refining the MDSContext class.
+* Reversion: Reverted a prior change that moved MDSContext completion handling to the finish method.
+* Segmentation fault fixed due to incorrect queueing of request retries.
+
+OSD (Object Storage Daemon)
+---------------------------
+
+* FastEC Activation: Always updates the pwlc epoch when activating.
+* PGLog Missed List: Fixed a bug to ensure the correct version is attached to the missing list when ignoring log entries.
+* Data Integrity Asserts: Added assertions to explicitly catch potential corruption in the OSD missing list.
+* Data Structure Changes: Modified the rmissing map key type from version_t to eversion_t.
+* Rollback & Vector Fixes: Corrected rollback logic for partial write object information (OI) and optimized Erasure Coding (EC) by ensuring Twiddle creates a full-sized vector.
+
+RGW (RADOS Gateway)
+-------------------
+
+* Lifecycle Management: Fixed lifecycle transition issues affecting encrypted multipart objects.
+* Multisite Concurrency: Improved concurrency handling when a value of 1 is provided by the caller, added logging for concurrency state transitions within adj_concurrency, exposed lock latency as a performance counter for data synchronization, and fixed an uninitialized LatencyMonitor average by shifting to an exponentially weighted moving average.
+* REST & Query Handling: RESTArgs::get_string() now properly URL-decodes incoming query parameters.
+
+RADOS / librados / neorados
+---------------------------
+
+* Linger Operations: Rewrote safety checks to eliminate use-after-free vulnerabilities and LingerOp memory leaks when an unwatch operation returns ENOTCONN. Replaced the flawed is_valid_watch() check with a safe linger_by_cookie() lookup which safely manages LingerOp references using intrusive_ptr. Ensured librados linger callbacks hold a persistent reference to LingerOp to protect against races with simultaneous linger_cancel() requests. Configured librados::IoCtxImpl::aio_unwatch() to asynchronously deliver ENOTCONN to AioCompletion instead of returning the error directly.
+* Watch/Notify: Fixed neorados notification queue bounds enforcement so that an overflow marker is only appended on the first message exceeding capacity, rather than duplicating it on every subsequent message. Prevented double-cleanup triggers in watch/notify operations when incoming errors arrive after maybe_cleanup() runs. Fixed a bug where notify would lose original error values by ensuring it no longer attempts to decode empty responses. Enhanced io_context shutdown procedures to clear handlers and route cleanly through linger_cancel to avoid use-after-free states.
+* Async Utilities: Fixed an issue regarding the improper removal of objects from the async service list.
+
+Dashboard
+-----------------
+
+* NVMeoF Revamp: Complete UI overhaul with DHCHAP controller key support, namespace encryption, and secure listeners configuration.
+* Pools & RGW: Added stretch cluster validation for pools, fixed RGW restart/stop issues, storage class restrictions, sync policy fixes, and MSR EC Profile support.
+* NFS: Toggle visibility for CephFS snapshots, fixed export creation and path value consistency issues
+
+ceph-volume
+-----------
+
+* Inventory Scanning: Enhanced inventory discovery logic to automatically skip RAM disk devices (/dev/ram*).
+
+External Block Device (extblkdev)
+---------------------------------
+
+* Plugin Stability: Fixed an assertion failure in the FCM plugin when encountering multivolume devices.
