Google stops supporting anything below the current shipping version. I think Chrome 12 is the shipping stable version, and Dev is at 14, so in chrome time, version 10 is archaic. But Chrome has the automatic auto-update feature which makes something like 90% of installations upgrade to the latest release within a week of its publication, so versions aren't nearly as much of an issue.
