Short description of error
The behavior in the node editors has changed. Whereas before you could move a node with G > Confirm, now the user has to hold down the G key to move. Releasing G causes the translate operator to stop.
Any hotkey that results in nodes in the node editor (both shader editor and compositor) moving with the mouse now stops the movement as soon as the keyboard key is lifted, as opposed to continuing to move until mousebutton1 is pressed (which is/was the behaviour elsewhere in blender and in the node editor in the past iirc).
Examples are obviously G but also Shift+D (nodes created by duplication stop moving as soon as the D key is released)
strangely Shift+A does not have this problem, any new nodes that are added (but not made by duplicating) continue to move with the mouse as expected.
This makes the node editors almost unuseable for users accustomed to using hotkeys
