Are there ways to know what might brake when upgrading?
I think the release notes are probably the best documentation of any breaking changes. In the case of Isadora 2 to 3, we had the shift to 64bit which killed some 32bit fx (thinking about FFGL 32bit here), these where really beyond our control. We don't get rid of things as we add updated/replacement features, instead we take the approach of making things 'classic' and phasing them out so that projects have an easier update path.
Some search features would be helpful. I would love to get a report for any given actor that provides the breadcrumb path to any instance of an actor. These are things we have talked about and I hope we can get into the software.
