- 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 as ``A | 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.
