Untargeted specs¶
Note
The following specs have been approved but have not been completed in the originally planned release. Rather than remove them, they have been made ‘untargeted’ for future reference. If you would like to work on one of these specs, please re-propose it for the appropriate release. The review will most likely be quick, but we need to make sure that everyone still understands the spec as written, and that it still fits in with the Cinder project’s plans.
