hi,

We are using Drools 4.0.7 at present and looking to move to Drools 5.0. How
long is the old API expected to be supported? This will help us plan by when
we'll need to refactor our code to use the new APIs.

What about the rules in existing DRL files? I read in another post that they
are backward compatible. Will there be a huge learning curve in
understanding the new DRL syntax so that it can be used for upcoming rules?
Is there a problem in using the new DRL syntax with old Drools APIs?

Thanks,
Sobhana
