CHANGELOG

+swift (2.16.0)
+
+    * Add checksum to object extended attributes.
+
+    * Let clients request heartbeats during SLO PUTs by including
+      the query parameter `heartbeat=on`.
+
+      With heartbeating turned on, the proxy will start its response
+      immediately with 202 Accepted then send a single whitespace
+      character periodically until the request completes. At that
+      point, a final summary chunk will be sent which includes a
+      "Response Status" key indicating success or failure and (if
+      successful) an "Etag" key indicating the Etag of the resulting
+      SLO.
+
+    * Added support for retrieving the encryption root secret from an
+      external key management system. In practice, this is currently limited
+      to Barbican.
+
+    * Move listing formatting out to a new proxy middleware named
+      `listing_formats`. `listing_formats` should be just right of the
+      first proxy-logging middleware, and left of most other
+      middlewares. If it is not already present, it will be
+      automatically inserted for you.
+
+      Note: if you have a custom middleware that makes account or
+      container listings, it will only receive listings in JSON format.
+
+    * Log deprecation warning for `allow_versions` in the container
+      server config. Configure the `versioned_writes` middleware in
+      the proxy server instead. This option will be ignored in a
+      future release.
+
+    * Replaced `replication_one_per_device` by custom count defined by
+      `replication_concurrency_per_device`. The original config value
+      is deprecated, but continues to function for now. If both values
+      are defined, the old `replication_one_per_device` is ignored.
+
+    * Fixed a rare issue where multiple backend timeouts could result
+      in bad data being returned to the client.
+
+    * Cleaned up logged tracebacks when talking to memcached servers.
+
+    * Account and container replication stats logs now include
+      `remote_merges`, the number of times a whole database was sent
+      to another node.
+
+    * Respond 400 Bad Request when Accept headers fail to parse
+      instead of returning 406 Not Acceptable.
+
+    * The `domain_remap` middleware now supports the
+      `mangle_client_paths` option. Its default "false" value changes
+      `domain_remap` parsing to stop stripping the `path_root` value
+      from URL paths. If users depend on this path mangling, operators
+      should set `mangle_client_paths` to "True" before upgrading.
+
+    * Remove `swift-temp-url` script. The functionality has been in
+      swiftclient for a long time and this script has been deprecated
+      since 2.10.0.
+
+    * Removed all `post_as_copy` related code and configs. The option
+      has been deprecated since 2.13.0.
+
+    * Fixed XML responses (eg on bulk extractions and SLO upload
+      failures) to be more correct. The enclosing "delete" tag was
+      removed where it doesn't make sense and replaced with "extract"
+      or "upload" depending on the context.
+
+    * Static Large Object (SLO) manifest may now (again) have zero-byte
+      last segments.
+
+    * Fixed an issue where background consistency daemon child
+      processes would deadlock waiting on the same file descriptor.
+
+    * Removed a race condition where a POST to an SLO could modify the
+      X-Static-Large-Object metadata.
+
+    * Accept a trade off of dispersion for balance in the ring builder
+      that will result in getting to balanced rings much more quickly
+      in some cases.
+
+    * Fixed using `swift-ring-builder set_weight` with more than one
+      device.
+
+    * When requesting objects, return 404 if a tombstone is found and
+      is newer than any data found. Previous behavior was to return
+      stale data.
+
+    * Various other minor bug fixes and improvements.
+
+
+
 swift (2.15.1)
     * Fixed a bug introduced in 2.15.0 where the object reconstructor
       would exit with a traceback if no EC policy was configured.
