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. (See these 18 extensions worth downloading for Chrome to get started with Chrome extensions.) Mac users also gain support for much-needed bookmark sync and support for favicon-only pinned tabs.

Other changes across platforms are a little less exciting, but Mac users who've been waiting for Chrome to get the better features available on other platforms should be happy. Check out the dev channel blog post for the full changelog.
