swift (2.25.1, ussuri stable backports)
* Python 3 bug fixes:
* Fixed an error when reading encrypted data that was written while
running Python 2 for a path that includes non-ASCII characters. This
was caused by a difference in string types that resulted in
ambiguity when decrypting. To prevent the ambiguity for new data, set
`meta_version_to_write = 3` in your keymaster configuration after
upgrading all proxy servers.
If upgrading from Swift 2.20.0 or Swift 2.19.1 or earlier, set
`meta_version_to_write = 1` in your keymaster configuration prior
to upgrading.
* Object expiration respects the `expiring_objects_container_divisor`
config option.
* `fallocate_reserve` may be specified as a percentage in more places.
* The ETag-quoting middleware no longer raises TypeErrors.
* Improved how containers reclaim deleted rows to reduce locking and object
update throughput.
* Fix a proxy-server error when retrieving erasure coded data when
there are durable fragments but not enough to reconstruct.
* Fixed some SignatureDoesNotMatch errors when using the AWS .NET SDK.
* Region name config option is now respected when configuring S3 credential
caching.

upgrade:

**If your cluster has encryption enabled and is still running Swift
under Python 2**, we recommend upgrading Swift *before* transitioning to
Python 3. Otherwise, new writes to objects with non-ASCII characters
in their paths may result in corrupted downloads when read from a
proxy-server still running old swift on Python 2. See `bug 1888037
<https://bugs.launchpad.net/swift/+bug/1888037>`__ for more information.

The above bug was caused by a difference in string types that resulted
in ambiguity when decrypting. To prevent the ambiguity for new data, set
``meta_version_to_write = 3`` in your keymaster configuration *after*
upgrading all proxy servers.
If upgrading from Swift 2.20.0 or Swift 2.19.1 or earlier, set
``meta_version_to_write = 1`` in your keymaster configuration *prior*
to upgrading.
See the provided ``keymaster.conf-sample`` for more information about
this setting.
