Important notes¶
Database result backend related setting names changed from
sqlalchemy_*
->database_*
.The
sqlalchemy_
named settings won’t work at all in this version so you need to rename them. This is a last minute change, and as they were not supported in 3.1 we will not be providing aliases.chain(A, B, C)
now works the same way asA | B | C
.This means calling
chain()
might not actually return a chain, it can return a group or any other type depending on how the workflow can be optimized.
