+
+    * S3 API improvements
+
+      * CORS preflights are now allowed for pre-signed URLs.
+
+      * The `storage_domain` option now accepts a comma-separated list of
+        storage domains. This allows multiple storage domains to configured
+        for use with virtual-host style addressing.
+
+      * Fixed the types of configured values in /info response.
+
+      * Fixed a server error when trying to copy objects with non-ASCII names.
+
+      * Fixed a server error when uploading objects with very long names.
+        A KeyTooLongError is now returned.
+
+      * Fixed an error when multi-deleting MPUs when SLO async-deletes
+        are enabled.
+
+      * Fixed an error that allowed list-uploads and list-parts requests to
+        return incomplete or out-of-order results.
+
+      * Fixed several bugs when dealing with non-ASCII object names and
+        multipart uploads.
+
+      * Reduced the overhead of retrieving bucket and object ACLs.
+
+    * Replication, reconstruction, and diskfile improvements
+
+      * The reconstructor now uses the replication network to fetch fragments
+        for reconstruction.
+
+      * Added the ability to limit how many objects per handoff partition
+        will be reverted in a reconstructor cycle using the new
+        `max_objects_per_revert` option. This may be useful to reduce
+        ssync timeouts and lock contention, ensuring that progress is made
+        during rebalances.
+
+      * Ensure that non-durable data and .meta files are purged from handoffs
+        after syncing.
+
+      * Fixed tracebacks when there's a race to mark a file durable or delete it.
+
+      * Improved cooperative multitasking during ssync.
+
+      * Upon detecting a ring change, the reconstructor now only aborts the
+        jobs for that ring and continues processing jobs for other rings.
+
+      * Fixed a traceback when logging about a lock timeout in the replicator.
+
+    * Object updater improvements
+
+      * Added the ability to ratelimit updates (approximately) per-container
+        using the new `max_objects_per_container_per_second` option. This may
+        be used to limit requests to already-overloaded containers while still
+        making progress on updates to other containers.
+
+      * Added timing stats by response code.
+
+      * Updates are now sent over the replication network.
+
+      * Fixed a race condition where swift would attempt to quarantine
+        recently-deleted updates.
+
+    * Memcache improvements
+
+      * Added the ability to configure a chance to skip checking memcache when
+        querying shard ranges. This allows some fraction of traffic to go to
+        disk and refresh memcache before the key ages out. Recommended values
+        for the new `container_updating_shard_ranges_skip_cache_pct` and
+        `container_listing_shard_ranges_skip_cache_pct` options are in the
+        range of 0.0 to 0.1.
+
+      * Added stats for shard range cache hits, misses, and skips.
+
+      * Improved handling of timeouts and other errors when obtaining a
+        connection to memcached.
+
+    * Recon improvements
+
+      * Added object-reconstructor stats to recon.
+
+      * Each object-server IP is now queried only once when reporting disk
+        usage. Previously, each port in the ring would be queried; when using
+        servers-per-port, this could dramatically overstate the disk capacity
+        in the cluster.
+
+    * Fixed a security issue where tempurl and s3api signatures were logged in
+      full. This allowed an attacker with access to log data to perform replay
+      attacks, potentially accessing or overwriting cluster data. Now, such
+      signatures are redacted in a manner similar to auth tokens; see the
+      `reveal_sensitive_prefix` option in `proxy-server.conf`.
+
+      See CVE-2017-8761 for more information.
+
+    * Added a new `swift.common.registry` module. This includes helper
+      functions `register_sensitive_header` and `register_sensitive_param`
+      which third party middleware authors may use to flag headers and query
+      parameters for redaction when logging. For more information, see
+      https://docs.openstack.org/swift/latest/misc.html#module-swift.common.registry
+
+    * Added the ability to configure project-scope read-only roles for
+      keystoneauth using the new `project_reader_roles` option.
+
+    * The cname_lookup middleware now works with dnspython 2.0 and later.
+
+    * The internal clients used by the container-reconciler, container-sharder,
+      container-sync, and object-expirer daemons now use a more-descriptive
+      `<daemon>-ic` log name, rather than `swift`. If you previously
+      configured the `log_name` option in `internal-client.conf`, you must
+      now use the `set log_name = <value>` syntax to configure it, even if
+      no value is set in the `[DEFAULT]` section. This may be done prior to
+      upgrading.
+
+    * Fixed a bug that allowed some statsd metrics to be annotated with the
+      wrong backend layer.
+
+    * The `StatsdClient.set_prefix` method is now deprecated and
+      may be removed in a future release; by extension, so is the
+      `LogAdapter.set_statsd_prefix` method. Middleware developers should
+      use the `statsd_tail_prefix` argument to `get_logger` instead.
+
+    * Fixed a traceback in the account-server when there's no account
+      database on disk to receive a container update. The account-server
+      now correctly 404s.
+
+    * The container-updater will quarantine container databases if all
+      replicas for the account respond 404.
+
+    * Fixed a proxy-server error when the read-only middleware tried to
+      handle non-Swift paths (such as may be used by third-party middleware).
+
+    * Some client behaviors that the proxy previously logged at warning have
+      been lowered to info.
+
+    * Removed translations from most logging.
+
+    * Various other minor bug fixes and improvements.
