We see a lot of really cool features in the unstable versions of Chrome, like vertical tabs, extension syncing and web app support, but it seems like it takes forever for them to show up in the stable builds. As a result, Google has decided that they're going to update Chrome twice as often.
Apparently the longer release schedule put too much pressure on developers to get new features ready on time, because if they didn't, they'd have to wait three months before the next update. Now they're going to release a new stable version every six weeks, meaning we get to see those features sooner.
