+swift (2.10.0, OpenStack Newton)
+
+    * Object versioning now supports a "history" mode in addition to
+      the older "stack" mode. The difference is in how DELETE requests
+      are handled. For full details, please read
+      http://docs.openstack.org/developer/swift/overview_object_versioning.html.
+
+    * New config variables to change the schedule priority and I/O
+      scheduling class. Servers and daemons now understand
+      `nice_priority`, `ionice_class`, and `ionice_priority` to
+      schedule their relative importance. Please read
+      http://docs.openstack.org/developer/swift/deployment_guide.html
+      for full config details.
+
+    * On newer kernels (3.15+ when using xfs), Swift will use the O_TMPFILE
+      flag when opening a file instead of creating a temporary file
+      and renaming it on commit. This makes the data path simpler and
+      allows the filesystem to more efficiently optimize the files on
+      disk, resulting in better performance.
+
+    * Erasure code GET performance has been significantly
+      improved in clusters that are not completely healthy.
+
+    * Significant improvements to the api-ref doc available at
+      http://developer.openstack.org/api-ref/object-storage/.
+
+    * A PUT or POST to a container will now update the container's
+      Last-Modified time, and that value will be included in a
+      GET/HEAD response.
+
+    * Include object sysmeta in POST responses. Sysmeta is still
+      stripped from the response before being sent to the client, but
+      this allows middleware to make use of the information.
+
+    * Fixed a bug where a container listing delimiter wouldn't work
+      with encryption.
+
+    * Fixed a bug where some headers weren't being copied correctly
+      in a COPY request.
+
+    * Container sync can now copy SLOs more efficiently by allowing
+      the manifest to be synced before all of the referenced segments.
+      This fixes a bug where container sync would not copy SLO manifests.
+
+    * Fixed a bug where some tombstone files might never be reclaimed.
+
+    * Update dnspython dependency to 1.14, removing the need to have
+      separate dnspython dependencies for Py2 and Py3.
+
+    * Deprecate swift-temp-url and call python-swiftclient's
+      implementation instead. This adds python-swiftclient as an
+      optional dependency of Swift.
+
+    * Moved other-requirements.txt to bindep.txt. bindep.txt lists
+      non-python dependencies of Swift.
+
+    * Various other minor bug fixes and improvements.

     * Swift now supports at-rest encryption. This feature encrypts all
