CHANGELOG

+swift (2.19.0)
+
+    * TempURLs now support IP range restrictions. Please see
+      https://docs.openstack.org/swift/latest/middleware.html#client-usage
+      for more information on how to use this additional restriction.
+
+    * Add support for multiple root encryption secrets for the trivial
+      and KMIP keymasters. This allows operators to rotate encryption
+      keys over time without needing to re-encrypt all existing data
+      in the cluster. Please see the included sample config files for
+      instructions on how to multiple encryption keys.
+
+    * The object updater now supports two configuration settings:
+      "concurrency" and "updater_workers". The latter controls how many
+      worker processes are spawned, while the former controls how many
+      concurrent container updates are performed by each worker
+      process. This should speed the processing of async_pendings.
+
+      On upgrade, a node configured with concurrency=N will still handle
+      async updates N-at-a-time, but will do so using only one process
+      instead of N.
+
+      If you have a config file like this:
+
+          [object-updater]
+          concurrency = <N>
+
+      and you want to take advantage of faster updates, then do this:
+
+          [object-updater]
+          concurrency = 8  # the default; you can omit this line
+          updater_workers = <N>
+
+      If you want updates to be processed exactly as before, do this:
+
+          [object-updater]
+          concurrency = 1
+          updater_workers = <N>
+
+    * When listing objects in a container in json format, static large
+      objects (SLOs) will now include an additional new "slo_etag" key
+      that matches the etag returned when requesting the SLO. The
+      existing "hash" key remains unchanged as the MD5 of the SLO
+      manifest. Text and XML listings are unaffected by this change.
+
+    * Log deprecation warnings for `run_pause`. This setting was
+      deprecated in Swift 2.4.0 and is replaced by `interval`.
+      It may be removed in a future release.
+
+    * Object reconstructor logs are now prefixed with information
+      about the specific worker process logging the message. This
+      makes reading the logs and understanding the messages much simpler.
+
+    * Lower bounds of dependencies have been updated to reflect what
+      is actually tested.
+
+    * SSYNC replication mode now removes as much of the directory
+      structure as possible as soon at it observes that the directory
+      is empty. This reduces the work needed for subsequent replication
+      passes.
+
+    * The container-updater now reports zero objects and bytes used for
+      child DBs in sharded containers. This prevents double-counting in
+      utilization reports.
+
+    * Add fallocate_reserve to account and container servers. This
+      allows disks shared between account/container and object rings to
+      avoid getting 100% full. The default value of 1% matches the
+      existing default on object servers.
+
+    * Added an experimental `swift-ring-composer` CLI tool to build
+      composite rings.
+
+    * Added an optional `read_only` middleware to make an entire cluster
+      or individual accounts read only.
+
+    * Fixed a bug where zero-byte PUTs would not work properly
+      with "If-None-Match: *" conditional requests.
+
+    * ACLs now work with unicode in user/account names.
+
+    * COPY now works with unicode account names.
+
+    * Improved S3 API compatibility.
+
+    * Lock timeouts in the container updater are now logged at INFO
+      level, not ERROR.
+
+    * Various other minor bug fixes and improvements.
