swift (2.25.0, OpenStack Ussuri)
* WSGI server processes can now notify systemd when they are ready.
* Added a new middleware that allows users and operators to configure
accounts and containers to use RFC-compliant (i.e., double-quoted)
ETags. This may be useful when using Swift as an origin for some
content delivery networks. For more information, see
https://docs.openstack.org/swift/latest/middleware.html#etag-quoter
* Added `ttfb` (Time to First Byte) and `pid` (Process ID) to the set
of available proxy-server log fields. For more information, see
https://docs.openstack.org/swift/latest/logs.html
* Improved proxy-server performance by reducing unnecessary locking,
memory copies, and eventlet scheduling.
* Reduced object-replicator and object-reconstructor CPU usage by only
checking that the device list is current when rings change.
* Improved performance of sharded container listings when performing
prefix listings.
* Improved container-sync performance when data has already been
deleted or overwritten.
* Account quotas are now enforced even on empty accounts.
* Getting an SLO manifest with `?format=raw` now responds with an ETag
that matches the MD5 of the generated body rather than the MD5 of
the manifest stored on disk.
* Provide useful status codes in logs for some versioning and symlink
subrequests that were previously logged as 499.
* Fixed 500 from cname_lookup middleware. Previously, if the looked-up
domain was used by domain_remap to update the request path, the
server would respond Internal Error.
* On Python 3, fixed an issue when reading or writing objects with a
content-type like `message/*`. Previously, Swift would fail to respond.
* On Python 3, fixed a RecursionError in swift-dispersion-report when
using TLS.
* Fixed a bug in the new object versioning API that would cause more
than `limit` results to be returned when listing.
* Various other minor bug fixes and improvements.
