When is Chrome 28 arriving? I'm using Firefox and Chrome on my Mac. And today I've updated Flash for all browsers, except Chrome. The Flash plugin in Chrome is old now and needs an update. But no new Chrome there. :-(
Flash will bring Chrome down. They even have their own Flash bugs they don't fix as fast as Adobe(!).

The update is rolling out gradually. If you would like to make sure you're on the latest version, you can select "About Google Chrome" from the "Chrome" menu on Mac. That will take you to a page that shows you which version you're running and checks for updates.
As the release blog mentions, the Flash update is rolling out via the component updater, which updates Flash independently of the rest of Chrome.
Here are the current versions of Flash: http://www.adobe.com/software/flash/about/
After the update to Chrome 28, I still had Flash 11.7. The blog post says that Flash 11.8.800.97 (the latest version) is rolling out via the component updater. I don't think there's any UI to trigger a component update, but it should happen naturally by itself.
In chrome://plugins/ (+ "Details") I can choose between Chrome's Flash and the "normal" Flash.
EDIT: Woops, I just checked and I'm already on 28! Awesome :-)
