Wallaby Series Release Notes¶
A filter-based usage enforcement framework is introduced in this release. Enforcement filters allow operators to define lease constraints. The first filter introduced in this release restricts maximum lease duration.
The default value of the
[oslo_policy]/policy_fileconfiguration option has been changed from
policy.yaml. Operators using customized or previously generated static policy JSON files (which are not needed by default) should generate new policy files or convert them to YAML format. Use the oslopolicy-convert-json-to-yaml tool to convert a policy file from JSON to YAML in a backward-compatible way.
Use of JSON-formatted policy files was deprecated by the
oslo.policylibrary during the Victoria development cycle. As a result, this deprecation is being noted in the Wallaby cycle with an anticipated future removal of support by
oslo.policy. As such operators will need to convert to YAML-formatted policy files. Please see the upgrade notes for details on migration of any custom policy files.
Fixes database migrations with Alembic 1.5.0 or greater. For more details, see bug 1912502.
