[rules-users] Is 3.1 M1 backward compatible?

The syntax is backwards compatible. However as the release notes mention 
we no longer autobox primitives, as you can now work directly with them, 
which will cause issues in  old drls that assumed numbers are wrapped. 
Also pojos must have a default constructor and not use the final keyword 
at the class and method level - we are actively looking to add more 
flexability to this case.
