upgrade:
- |
New paste pipelines and middleware have been created to allow API version
discovery to be performed without authentication or redirects. Because this
involves an ``api-paste.ini`` change, you will need to manually update your
``api-paste.ini`` with the one from the release to get this functionality.
fixes:
- |
When using the ``api-paste.ini`` from the release, version discovery
requests without a trailing slash will no longer receive a 302 redirect to
the corresponding URL with a trailing slash (e.g. a request for ``/v2.1``
will no longer redirect to ``/v2.1/``). Instead, such requests will respond
with the version discovery document regardless of the presence of the
trailing slash. See
`bug 1728732 <https://bugs.launchpad.net/nova/+bug/1728732>`_ for details.
- |
When using the ``api-paste.ini`` from the release, requests to the
versioned discovery endpoints (``/v2.1`` and ``/v2``) no longer require
authentication. When using the compute API through certain clients, such as
openstacksdk, this eliminates an unnecessary additional query. See
`bug 1845530 <https://bugs.launchpad.net/nova/+bug/1845530>`_ for details.
