+swift (2.11.0)
+
+    * We have made significant improvements and changes to the erasure
+      code implementation.
+
+      - Instead of using a separate .durable file to indicate the
+        durable status of an EC fragment archive, we rename the .data
+        to include a durable marker in the filename. This saves one
+        inode for every EC .data file. Existing .durable files will not
+        be removed, and they will continue to work just fine.
+
+        Note that after writing EC data with Swift 2.11.0 or later, that
+        data will not be accessible to earlier versions of Swift.
+
+      - Closed a bug where ssync may have written bad fragment data in
+        some circumstances. A check was added to ensure the correct number
+        of bytes is written for a fragment before finalizing the write.
+        Also, erasure coded fragment metadata will now be validated on read
+        requests and, if bad data is found, the fragment will be quarantined.
+
+      - The improvements to EC reads made in Swift 2.10.0 have also been
+        applied to the reconstructor. This allows fragments to be rebuilt
+        in more circumstances, resulting in faster recovery from failures.
+
+      - WARNING: If you are using the ISA-L library for erasure codes,
+        please upgrade to liberasurecode 1.3.1 (or later) as soon as
+        possible. If you are using isa_l_rs_vand with more than 4 parity,
+        please read https://bugs.launchpad.net/swift/+bug/1639691 and take
+        necessary action.
+
+      - Updated the PyECLib dependency to 1.3.1.
+
+    * Added a configurable URL base to staticweb.
+
+    * Support multi-range GETs for static large objects.
+
+    * TempURLs using the "inline" parameter can now also set the
+      "filename" parameter. Both are used in the Content-Disposition
+      response header.
+
+    * Mirror X-Trans-Id to X-Openstack-Request-Id.
+
+    * SLO will now concurrently HEAD segments, resulting in much faster
+      manifest validation and object creation. By default, two HEAD requests
+      will be done at a time, but this can be changed by the operator via
+      the new `concurrency` setting in the "[filter:slo]" section of
+      the proxy server config.
+
+    * Suppressed the KeyError message when auditor finds an expired object.
+
+    * Daemons using InternalClient can now be properly killed with SIGTERM.
+
+    * Added a "user" option to the drive-audit config file. Its value is
+      used to set the owner of the drive-audit recon cache.
+
+    * Throttle update_auditor_status calls so it updates no more than once
+      per minute.
+
+    * Suppress unexpected-file warnings for rsync temp files.
+
+    * Various other minor bug fixes and improvements.

     * Object versioning now supports a "history" mode in addition to
