Unity 6.5 introduces a powerful new Lifecycle Management API that finally makes fast iteration with Domain Reload disabled both safe and practical. In this deep dive, we explore all the major new attributes including [AutoStaticsCleanup], [OnEnteringPlayMode], [OnExitingPlayMode], [OnCodeInitializing], [OnCodeUnloading], and more. Learn how these tools solve long-standing issues with static state leaks, event handler accumulation, and tricky initialization timing — while preparing your project for the upcoming CoreCLR transition in Unity 6.8. Whether you're on the 6.5 beta or using the community backport, this video will show you practical examples, migration strategies, and when to use each attribute.
