The big story is cleanup enabling speed: the team is deleting the last of the old bridge code while cutting the cost of every scroll frame.
First, bridgeless is now the only path. About half of today's activity removes bridge-mode branches that never execute. Pull request 59260 simplifies developer settings to bridgeless only, and pull request 59264 does the same for component data, with matching changes to the performance monitor, linking manager, and…
Second, scrolling does less wasted work. Pull request 59134 makes Virtualized List check the render window before scheduling state, avoiding a full render pass when nothing changed.
