New Feature Planning

If you want to add new functionality to Mistral please file a blueprint by following

We don’t have a strict requirement to write a detailed specification for all new features and rather encourage more agile approach: just file a brief description of a feature in the form of blueprint and then send a patch to review (linking it to the blueprint). However, in some rare cases, like proposing new API or workflow language additions, we need a spec so that the team could fully understand what’s going to be done and provide a feedback.

To file a specification for a new feature, send a patch to that adds a new spec file for the needed release cycle (e.g. ‘specs/victoria’)

The full list of the specs can be seen at
