[s3ql] [ANNOUNCE] S3QL 6.2.1 has been released

[Nikolaus Rath]

Dear all,

I am pleased to announce a new release of S3QL, version 6.2.1.

From the changelog:

* Fixed a crash in the HTTP client when a server emits more than one ``Date``
header in a response (observed against some real OpenStack Swift
deployments).

* Fixed a crash when using the Amazon S3 backend and attempting to
delete multiple objects.

* Fixed the Google Cloud Storage backend hanging indefinitely on startup when
the server returns ``Content-Type: application/json; charset=utf-8`` (without
quotes around the charset value).

* Fixed the Backblaze B2 backend (``b2://`` URL scheme): startup no longer
fails with ``HTTPError: 403`` for accounts whose bucket does not live in
the ``us-east-005`` region.

* This release still ships with the ``b2old://`` backend in case some users are
unable to use the rewritten ``b2://`` backend. The `b2old` backend will be
removed in a future release if no regressions are reported - so please file
an issue at https://github.com/s3ql/s3ql/issues if you encounter any
problems with ``b2://``.
