+swift (2.30.0)
+
+    * Sharding improvements
+
+      * The `swift-manage-shard-ranges` tool has a new mode to repair gaps
+        in the namespace.
+
+      * Misplaced tombstone records are now properly cleaved.
+
+      * Fixed a bug where the sharder could fail to find a device to use for
+        cleaving.
+
+      * Databases marked deleted are now processed by the sharder.
+
+      * More information is now synced to the fresh database when sharding.
+        Previously, a database could lose the fact that it had been marked
+        as deleted.
+
+      * Shard ranges with no rows to cleave could previously be left in the
+        CREATED state after cleaving. Now, they are advanced to CLEAVED.
+
+      * Metrics are now emitted for whether databases used for cleaving
+        were created or already existed, allowing a better understanding
+        of the reason for handoffs in the cluster.
+
+      * Misplaced-record stats are now also emitted to statsd. Previously,
+        these were only available in logs.
+
+    * S3 API improvements
+
+      * Constant-time string comparisons are now used when checking signatures.
+
+      * Fixed cross-policy object copies. Previously, copied data would
+        always be written using the source container's policy. Now, the
+        destination container's policy will be used, avoiding availability
+        issues and unnecessary container-reconciler work.
+
+      * More headers are now copied from multi-part upload markers to their
+        completed objects, including `Content-Encoding`.
+
+      * When running with `s3_acl` disabled, `bucket-owner-full-control` and
+        `bucket-owner-read` canned ACLs will be translated to the same Swift
+        ACLs as `private`.
+
+      * The S3 ACL and Delete Multiple APIs are now less case-sensitive.
+
+      * Improved the error message when deleting a bucket that's ever had
+        versioning enabled and still has versions in it.
+
+      * `LastModified` timestamps in listings are now rounded up to whole
+        seconds, like they are in responses from AWS.
+
+      * Proxy logging for Complete Multipart Upload requests is now more
+        consistent when requests have been retried.
+
+    * Logging improvements
+
+      * Signal handling is more consistently logged at notice level.
+        Previously, signal handling would sometimes be logged at info
+        or error levels.
+
+      * The message template for proxy logging may now include a
+        `{domain}` field for the client-provided `Host` header.
+
+      * The object-replicator now logs successful rsync transfers at debug
+        instead of info.
+
+      * Added a `log_rsync_transfers` option to the object-replicator.
+        Set it to false to disable logging rsync "send" lines; during
+        large rebalances, such logging can overwhelm log aggregation
+        while providing little useful information.
+
+      * Transaction IDs are now only included in daemon log lines
+        in a request/response context.
+
+    * Fixed a socket leak when clients try to delete a non-SLO as though
+      it were a Static Large Object.
+
+    * The formpost digest algorithm is now configurable via the new
+      `allowed_digests` option, and support is added for both SHA-256
+      and SHA-512. Supported formpost digests are exposed to clients in
+      `/info`. Additionally, formpost signatures can now be base64 encoded.
+
+    * Added metrics to the formpost and tempurl middlewares to monitor
+      digest usage in signatures.
+
+    * SHA-1 signatures are now deprecated for the formpost and tempurl
+      middlewares. At some point in the future, SHA-1 will no longer be
+      enabled by default; eventually, support for it will be removed
+      entirely.
+
+    * Improved compatibility with certain FIPS-mode-enabled systems.
+
+    * Added a `ring_ip` option for various object services. This may be
+      used to find own devices in the ring in a containerized environment
+      where the `bind_ip` may not appear in the ring at all.
+
+    * Account and container replicators can now be configured with a
+      `handoff_delete` option, similar to object replicators and
+      reconstructors. See the sample config for more information.
+
+    * Developers using Swift's memcache client may now opt in to having
+      a `MemcacheConnectionError` be raised when no connection succeeded
+      using a new `raise_on_error` keyword argument to `get`/`set`.
+
+    * The tempurl middleware has been updated to return a 503 if storing a
+      token in memcache fails. Third party authentication middlewares are
+      encouraged to also use the new `raise_on_error` keyword argument
+      when storing ephemeral tokens in memcache.
+
+    * Pickle support has been removed from Swift's memcache client. Support
+      had been deprecated since Swift 1.7.0.
+
+    * Device names are now included in new database IDs. This provides more
+      context when examining incoming/outgoing sync tables or sharding
+      CleaveContexts.
+
+    * Database replication connections are now closed following an error
+      or timeout. This prevents a traceback in some cases when the replicator
+      tries to reuse the connection.
+
+    * `ENOENT` and `ENODATA` errors are better handled in the object
+      replicator and auditor.
+
+    * Improved object update throughput by shifting some shard range
+      filtering from Python to SQL.
+
+    * Include `Vary: Origin` header when CORS responses vary by origin.
+
+    * The staticweb middleware now allows empty listings at the root of
+      a container. Previously, this would result in a 404 response.
+
+    * Ring builder output tables better display weights over 1000.
+
+    * Various other minor bug fixes and improvements.
+
+
 swift (2.29.1, OpenStack Yoga)
 
     * This is the final stable branch that will support Python 2.7.
