+swift (2.12.0)
+
+    * Ring files now include byteorder information about the endian of
+      the machine used to generate the file, and the values are
+      appropriately byteswapped if deserialized on a machine with a
+      different endianness.
+
+      Newly created ring files will be byteorder agnostic, but
+      previously generated ring files will still fail on different
+      endian architectures. Regenerating older ring files will cause
+      them to become byteorder agnostic. The regeneration of the ring
+      files will not cause any new data movement. Newer ring files
+      will still be usable by older versions of Swift (on machines
+      with the same endianness--this maintains existing behavior).
+
+    * All 416 responses will now include a Content-Range header with
+      an unsatisfied-range value. This allows the caller to know the
+      valid range request value for an object.
+
+    * TempURLs now support a validation against a common prefix. A
+      prefix-based signature grants access to all objects which share the
+      same prefix. This avoids the creation of a large amount of signatures,
+      when a whole container or pseudofolder is shared.
+
+    * Correctly handle deleted files with if-none-match requests.
+
+    * Correctly send 412 Precondition Failed if a user sends an
+      invalid copy destination. Previously Swift would send a 500
+      Internal Server Error.
+
+    * In SLO manifests, the `etag` and `size_bytes` keys are now fully
+      optional and not required. Previously, the keys needed to exist
+      but the values were optional. The only required key is `path`.
+
+    * Fixed a rare infinite loop in `swift-ring-builder` while placing parts.
+
+    * Ensure update of the container by object-updater, removing a rare
+      possibility that objects would never be added to a container listing.
+
+    * Fixed non-deterministic suffix updates in hashes.pkl where a partition
+      may be updated much less often than expected.
+
+    * Fixed regression in consolidate_hashes that occurred when a new
+      file was stored to new suffix to a non-empty partition. This bug
+      was introduced in 2.7.0 and could cause an increase in rsync
+      replication stats during and after upgrade, due to inconsistent
+      hashing of partition suffixes.
+
+    * Account and container databases will now be quarantined if the
+      database schema has been corrupted.
+
+    * Removed "in-process-" from func env tox name to work with
+      upstream CI.
+
+    * Respect server type for --md5 check in swift-recon.
+
+    * Remove empty db hash and suffix directories if a db gets quarantined.
+
+    * Various other minor bug fixes and improvements.
