Update not for all (for now)

Some of you asking me why the application is not available. It can't be installed from the Web Store or upgraded in browser.
As I mentioned in description of updates, new version requires Chrome version 23 (at least). All because it use Chrome API that is not available in older versions. Unfortunately current stable version is 21 and beta channel is 23. So only users with beta or dev channel may install or update application. 

It should change soon, when Chrome team release an update to stable version. Sorry for this inconvenience.
