Stan, Alex, Renat: 

Should we migrate to YAQL 1.0 now? and stop using the initial one? What’s the delta? 

Still short on the docs :) but I understand they’re coming up. 
https://github.com/stackforge/yaql/tree/master/doc/source

Cheers, Dmitri.

It is going to have proper documentation and high unit test coverage which can also serve as a documentation source. YAQL has already migrated to StackForge and adopted OpenStack development process and tools but the work is still in progress. Any help from Mistral team and/or other YAQL adopters is appreciated.
