[Pharo-dev] Is RBRefactoryChange alive, and what do I use for recategorization

Hi everyone. in my critic projects I need a concept of a “change” the can be previewed, executed or combined with other changes. I.e. if a critic can propose an automated solution, it has to be _something_. At the moment I’ve started to use RBRefactoryChange, but I want to know whether it is the thing to use, or maybe someone is preparing a replacement. Because classes have no comments. no real diff support and so on… If it is the thing to use, which change should I use for a recategorization (change protocol) of a method? Thanks. Uko
