This is for to branch from the original github fork.
There is another repo in this profile: friendica_2021.01_tupambae_shared_hosting
That repo was created by downloading 2021.01 as zip from github.
Classes added to core and testbubble theme
It looks to me as if view/wall_item.tpl is an earlier version that somehow didn't get merged. I don't think testbubble is using it, so I'm going to merge and then revert that one file, as I don't see any changes you made to it specifically for this body of work.
