Strong Undo/Redo - migf1 - 07-01-2020
Hey guys,
is there a comprehensive explanation of those 2 commands anywhere? Are they even still relevant?
Google didn't help me much, neither did the docs page. All I could find was a pretty vague "You can now undo/redo multiple steps at once, useful when experimenting", in some rather old Google results.

Yes, they are. From the source code:
For undo:
Code:
/*
* this function continues to undo as long as it only sees certain
* undo types, in particular visibility changes.
*/For redo:
Code:
/*
* this function continues to redo as long as it only sees certain
* undo types, in particular visibility changes. Note that the
* order of events is set up to make it exactly reverse
* gimp_image_strong_undo().
*/So it is mostly about skipping visibility changes in the undo stack.
