Windows/Mac/Linux: If you're living life on the bleeding edge of Google's Chrome browser, good news: Google just pushed out an update to the dev channel, improving HTML5 audio and video for all platforms, bringing extension and bookmark sync to Macs, and more.
The Windows build didn't see many changes, but Mac users should be particularly happy with the update. Having been excluded from extension support when the Chrome extension gallery first opened, Mac users can now officially join in the fun.
