Unity 6.5

Unity 6.5 adds a Profiler AI Assistant that surfaces optimization opportunities and helps troubleshoot performance issues directly in the Profiler, plus Project Auditor updates that flag APIs going obsolete between versions to ease upgrades. It also deprecates the long-standing Built-In Render Pipeline, which stays supported with fixes through the Unity 6.7 LTS lifecycle, so teams still on it should start planning a move to URP or HDRP.
