 - Fix erroneous central depth sampling in TAA.
 - Fixed light layers not correctly disabled when the lightlayers is set to Nothing and Lightlayers isn't enabled in HDRP Asset
+- Fixed a wrong condition in CameraSwitcher, potentially causing out of bound exceptions.
+- Fixed an issue where editing the Look Dev default profile would not reflect directly in the Look Dev window.

 - Slightly changed the TAA anti-flicker mechanism so that it is more aggressive on almost static images (only on High preset for now).
 - Changed default exposure compensation to 0.
 - Refactored shadow caching system.
+- Removed experimental namespace for ray tracing code.
