"Chrome has three levels of participation once a product is deemed ready to be released beyond the company’s own engineering base: Dev; Beta and Stable. 'Dev' is open to the developer community at large, allowing feedback and commentary from a sophisticated user group. The Beta channel has what Chrome’s Director of Product Management, Brian Rakowski, describes as 'reasonable stability' while the Stable channel, the one that just got upgraded, is intended for 'the majority of people who just want it to work.' According to Rakowski, this maps out at roughly 1%: 10%: 89% ratio of users."
