Release Notes for 633

Added Widget header with Device Selector and Mapping buttons.

Turning on and off UI visibility (including via StarterGui.ShowDevelopmentGui) no longer deactivates the select tool.

Certain properties in Studio settings wouldn't fire their :GetPropertyChangedSignal() events and now do.

Warns the first time an instance is added under the deprecated JointsService.

Adds the AudioFilter instance.

Fix persistent missing humanoid/accessory textures. Also fixes an issue where one composite avatar texture is used for the incorrect avatar.

Fixes disappearing lights in async lighting voxelization.

Allocates more stack memory for asynchronous light updates in different threads.

Thumbnails in the image picker should now be correct, even when there is a large number of images available.

When exporting files to .rbxlx, Studio no longer filters out Welds and Joints if they have only one of the two part fields (Part0 and Part1) set.

Fixed a race condition where preloadAsync might wait forever on loading meshes that were evicted during a time of heavy content loading.

Fixes a bug where doing multi-selections from the Explorer window would sometimes reselect instances that shouldn't be part of the selection.

game.CreatorId no longer always returns 0 when testing on the client for a published place and will now return the expected value.
