+features:
+ - |
+ There is now a tool in tripleo-heat-templates, similar to the
+ oslo-config-generator, that can be used to programmatically generate
+ sample environment files based directly on the contents of the templates
+ themselves. This ensures consistency in the sample environments, as well
+ as making it easier to update environments to reflect changes to the
+ templates.
+upgrade:
+ - |
+ Some sample environment files will be moving as part of the work to
+ generate them programmatically. The old versions will be left in place for
+ one cycle to allow a smooth upgrade process. When upgrading, if any of the
+ environment files in use for the deployment have been deprecated they
+ should be replaced with the new generated verions.
+deprecations:
+ - |
+ Where a generated sample environment replaces an existing one, the existing
+ environment is deprecated. This will be noted in a comment at the top of
+ the file.
