Dev news : Since #GIMP 2.99.12 release, I've been taking time to work on the upcoming developer website, documenting contribution howtos, but also reviewing and documenting algorithms.
Old wiki data such as roadmaps and build tutorials were moved there and improved.
More data needs to be moved from the wiki, but also from main source repo. New tutorials will need to be written. And we are planning to merge the GUI wiki (UX specifications and the like) in there too.
