EcmaScript 5 browser implementation

Question

So Safari and Chrome have started in their betas to implement some ES5 stuff. For instance Object.create is in them.

Do any of you know if there is a website that shows the progress made in the browsers? ATM i need to use Object.freeze, and wanted to see which browsers (if any) supported that yet.
