Hi, not directly related to this change but I was wondering if there is some kind of (official) documentation not only on the why of these changes, but also on the how?
Currently getting several deprecated warnings in my code editor when using an (old) factory method, stating that starting from version x the DI method should be used (not stating how (and where) one would do that).

Especially when trying to 'reverse' engineer things I run into core doing it with Factory classes itself (as the move to the 'new and improved' way is still in work in progress)

Maybe I'm searching in the wrong (deprecated :)) places, so any tips / pointers are appreciated.

@bembelimen updated most of the deprecation with proper replacement instructions, which parts do you need and missed to document? and if you found a solution please add it to manual.joomla.org
