+## Behind the scene changes
+
+* The X critical section is removed, picom no longer grabs the server to fetch updates. Hopefully, this change should be unnoticeable. Minor responsiveness improvements could be possible, but I won't bet on it. The main point of this change is this makes debugging much less painful. Previously if you breaks inside the X critical section, the whole X server will lock up, and you would have to connect to the computer remotely to recover. Now there is no longer such worries. This also avoids a bug inside Xorg that makes server grabbing unreliable.
