Squid is the 19th stable release of Ceph.
+v19.2.5 Squid
+=============
+This is the fifth backport release in the Squid series.
+We recommend that all users update to this release.
+
+Release Date
+------------
+
+July 14, 2026
+
+Notable Changes
+---------------
+
+MDS (Metadata Server)
+---------------------
+
+- Fixed a segmentation fault relating to MDSContext completion and request queuing.
+
+OSD (Object Storage Daemon)
+---------------------------
+
+- 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)
+-------------------
+
+- TLS 1.3 Ciphersuites: Introduced the ssl_ciphersuites configuration option for the Beast front-end to support TLS 1.3 cipher customizations.
+- S3 PutObject ACLs Fix: Fixed a bug where PutObject requests were erroneously rejected under BlockPublicAcls due to an incorrect comparison return value from canned_acl.compare().
+- Multisite Sync Robustness: Resolved an infinite loop scenario in RGWBucketFullSyncCR when a source bucket was deleted mid-sync by introducing a mechanism to clear stateful data in reused bucket_list_result objects.
+- SNS Policy Evaluation: Updated ListTopics to use the account root ARN for policy evaluation when invoked by a non-root account user, preventing unexpected implicit denies from identity-based policies.
+- Presigned URLs: Fixed an internal server error occurring during the authentication process of presigned URLs.
+- Prerequest Hook: Restructured the order of execution so that the prerequest hook now runs after the authorization process has completed.
+- Object Tagging: Added handling for plain-text object tags during execution of RGWObjTags::decode().
+- Beast Frontend Stability: Applied a strand executor to the Beast timeout timer to avoid concurrent socket access and potential race conditions.
+- Bucket Statistics: Added a fix for bucket stats execution when the underlying bucket index does not exist.
