+swift (2.32.0, OpenStack Bobcat)
+
+    * Python 3 fixes:
+
+      * Python 3 object servers can now read unencrypted non-ASCII metadata
+        that was written under Python 2.
+
+      * Ssync no longer corrupts unencrypted non-ASCII metadata during
+        transfers.
+
+      * Fixed an encoding issue when writing non-ASCII object names to sharded
+        containers and shard range caching is not enabled.
+
+      * Fixed an encoding issue when handling non-ASCII account names.
+
+      * Fixed a `generator already executing` error on client disconnect.
+
+      * Suppressed `RemoteDisconnected` tracebacks.
+
+    * Metrics improvements:
+
+      * Metrics are now emitted for a variety of S3 error responses, in the
+        form `s3api.<status_int>.<error_class>[.<reason>]`
+
+      * Fixed an issue that prevented proxy servers from emitting metrics and
+        logs for backend requests made when getting account or container info.
+
+      * Account and container info metrics now include the response status code
+        when backend requests are made.
+
+      * Added timing metrics to the container sharder for various operations.
+
+    * Python 3.11 is now supported.
+
+    * Added the ability for reseller admins to set per-policy account quotas by
+      posting metadata of the form `X-Account-Quota-Bytes-Policy-<policy name>`.
+
+    * Added a `keepalive_timeout` option to the proxy server to limit how long
+      to wait for a client to initiate a request, separate from the general
+      `client_timeout` option. Note that this requires eventlet 0.33.4
+      (currently unreleased) or later.
+
+    * Added a `keep_cache_slo_manifest` option to the object server to better
+      control whether SLO manifests are dropped from the page cache.
+
+    * WSGI servers now accept a `--test-config` option that may be used to
+      validate configuration changes before reloading/restarting the server.
+
+    * The structure of cached shard ranges has changed, improving performance
+      when listing or writing to sharded containers. Note that immediately
+      after upgrade, the new structures will all be cache misses, which may
+      lead to a thundering herd problem. To avoid this, upgrade just a few
+      nodes first, let them service some fraction of traffic to populate the
+      cache, then upgrade the rest of the cluster.
+
+    * A variety of performance improvements have been made for sharded
+      container databases.
+
+    * Various logging and metrics improvements when talking to memcache.
+
+    * Fixed ssync's handling of timestamp offsets. Previously, this could cause
+      ssync to fail with a 409 Conflict, causing the transfer to fail and
+      preventing handoffs from clearing.
+
+    * Fixed an issue where an erasure-coded PUT could prevent other requests
+      from being processed when network calls rarely or never blocked.
+
+    * Fixed an issue when downloading an SLO manifest would hit a recoverable
+      error and attempt to resume from another node. This would manifest as
+      either a pyeclib decode error or an unexpected empty response.
+
+    * The proxy server now applies error-limiting to the correct node when
+      handling a recoverable node error.
+
+    * Account, container, and object log fields are now correctly identified
+      when returning `BadDigest` responses to S3 requests.
+
+    * Previously, under some circumstances, a non-standard config option such
+      as `RECLAIM_AGE` might get parsed as `reclaim_age` for some processes
+      but ignored by others. Now, all config parsing is case-sensitive;
+      non-standard names will always be ignored.
+
+    * Reduced the backend load of making `?versions` requests to a container
+      that has never had object versioning enabled.
+
+    * Improved formatting of meta and sysmeta for `swift-account-info` and
+      `swift-container-info`.
+
+    * The standard-library `logging` module is no longer monkey-patched when
+      importing `swift.common.utils`, making it easier to re-use swift code
+      in other contexts.
+
+    * Removed the hard dependency on netifaces; it may still be used if the
+      `getifaddrs` C function is not available. This fallback support may be
+      removed in a future release.
+
+    * Various other minor bug fixes and improvements.
