I think it's worth being proactive in including the new stuff when possible, and this might be a good opportunity to do so.

Does Pd Vanilla have a comprehensive listing of new features for each release?

If so it would be helpful if someone could compile a list that has the
feature list per release.

>>> Hi,
>>> I have been checking pd vanilla "triggerize" feature, as Matt suggested, together with its undo system. It turns out that pd vanilla already has an atomic multi-step undo system implemented that allows us to start a sequence of undo actions, fill it with all actions that we need and then finalize it. Then, while undoing, if the system encounters the start/end of the sequence it executes all undo steps until the end/start is reached.

>>> I don't know what would be better. I have checked the implementation differences between vanilla and purr data and there are some of them that could probably break the system if we do a direct merge. Basically pd vanilla changed the place where the undo queue is stored and therefore how it's accessed, and some other implementation differences and add-ons.
