Release notes for 398

Beta Feature - removes the "Surface" option of JointCreationModes dropdown in Studio, consolidating to simply being 'on' or 'off'. This means if Surface Joining is on, all parts will join with a ManualWeld if flat coplanar sides are touching, regardless of surface type. Exceptions are for Hinge, Motor, and SteppingMotor surfaces.

Calling functions from math library (except for math.random/math.randomseed and Roblox extensions, math.noise/math.clamp/math.sign) as well as assert is now substantially faster with new Lua VM

Calling functions from bit32 library is now substantially faster with new Lua VM (minor exception: lshift/rshift/arshift expect arguments in [0..31] range, larger or negative arguments prevent the optimization from happening; extract/replace expect explicitly specified width argument)

CollisionFidelity is now Scriptable in Studio Command Line and Plugins

Under a studio setting, print some diagnostic information about game joins to the studio output window. Diagnostic information helps provide some information about how much data is sent from the server to join the game. Note that for games with StreamingEnabled set to True the reported Terrain bytes will always be 0 because of the timing of how Terrain is sent in StreamingEnabled games.

Comment Selection and Uncomment Selection will no longer be available in favor of having one button for Toggling comments. (Shortcut <Ctrl+Shift+c>)

Fixed auto-closing bracket commenting

Fix crash on Apple Intel HD 3000

Fixed a bug where parts would still float/collide with terrain water even if set to ignore the collision via Collision Groups or NoCollisionConstraint. Also fixed an issue where a canCollide=false part would still collide with water if listening on a touch event.

Streaming Pause UI is no longer shown on first occurrence to avoid displaying over loading screen.

Fixed being unable to click output logs to open the source script/line
