"""API Microversion definitions.
All new microversions should have a constant added here to be used throughout
the code instead of the specific version number. Until patches land, it's
common to end up with merge conflicts with other microversion changes. Merge
conflicts will be easier to handle via the microversion constants defined here
as the version number will only need to be changed in a single location.
Actual version numbers should be used:
* In this file
* In cinder/api/openstack/rest_api_version_history.rst
* In cinder/api/openstack/api_version_request.py
* In release notes describing the new functionality
* In updates to api-ref
Nearly all microversion changes should include changes to all of those
locations. Make sure to add relevant documentation, and make sure that
documentation includes the final version number used.
