[s3ql] [ANNOUNCE] S3QL 6.3.0 has been released

[Nikolaus Rath]

Dear all,

I am pleased to announce a new release of S3QL, version 6.3.0.

From the changelog:

* The legacy Backblaze B2 backend (the ``b2old://`` URL scheme) has been
removed.

* Fixed the Backblaze B2 backend failing region discovery with ``HTTPError:
400`` when used with newer API keys (the region-discovery request now uses
the V4 API endpoint).

* On the Amazon S3 and other S3-compatible backends, a response indicating that
the wrong region was configured is now reported at startup instead of being
silently worked around on every request.

* The ``compress`` setting in the authentication file (``authinfo2``) now
applies to every command. Previously ``mkfs.s3ql``, ``fsck.s3ql``,
``s3ql_verify``, and ``s3qladm`` always used ``lzma-2``. The default is now
``lzma-6``.

* Unknown keys in the authentication file (``authinfo2``) are now rejected
instead of being silently ignored.

* ``mkfs.s3ql`` and ``s3qladm`` no longer accept the ``--log`` option; they log
to stdout. ``fsck.s3ql`` no longer accepts the ``--compress`` option (the
``compress`` setting from the authentication file applies instead).

* Specifying an unknown storage backend in the storage URL now exits with the
usage-error code 2 (previously 11).
