[rules-users] Adding a custom operator to drools?

[Edson Tirelli]

   Michael,

   Drools 5 is not production ready yet, specially because we are still
working in the new major features like CEP and processes, but the 4.x
equivalent features all work. We still eventually break tests in trunk while
working on the new stuff, but you can most of the time simply ignore the
broken tests. Also, if your research project is not expected to be final in
the next month or so, by the time you finish your project we will have
Drools 5 final out.

   BTW, can you talk about about the subject of your research?
