Our Commentary ​

This is the core solid-js package RC, and it's got some good stuff. Making onHydrationEnd public again, even as experimental, is a win for testing and debugging hydration issues. The HMR and error boundary fixes are also crucial for a smooth developer experience. It feels like they're really buttoning up the rough edges for 2.0.0, which is exactly what you want to see in an RC.
