It was almost exactly one year ago that Google released the first dev build of Chrome for Mac and Linux. At the time, even though they released it, they didn’t really want you to use it. It simply wasn’t stable. Now it is. And as such, it’s finally being formally released.

Google announced today that Chrome for Mac and Linux has caught up with the stable (and older) Windows build of the browser. As such, they’re ready to take both builds out of beta for the first time. And these new stable releases come with new features such as more advanced syncing (bookmarks, preferences, settings, etc). And it’s full of HTML5 tools like Geolocation APIs, App Cache, and web sockets. And access to the over 4,500 Chrome extensions.

One thing not included in these new stable release is the new built-in Flash Player. Google actually had to remove that from the dev channel recently because it was causing issues [see: update]. Google promises that the integration will be ready by the time the final version of Flash 10.1 is released.

You can find the stable builds of Chrome for Mac and Linux here.

Also, in case you missed it, here’s the kick-ass Chrome speed-test video below.

Update: Adobe wrote to us to clarify why Flash wasn’t included in the stable build:

“Google locked down Chrome without the beta version of Flash Player 10.1 built-in since the plug-in is still in beta when Chrome 5.0 ships. Once we finalize Flash Player 10.1, it will be reintegrated into Chrome.”
