different release channels: download chrome developper channel for mac windows linux

Chrome supports a number of different release channels.  We use these channels to slowly roll out updates to users, starting with our close to daily Canary channel builds, all the way up to our Stable channel releases that happen every 6 weeks roughly.

-------------Dev channel (alpha channel):
Google has released Chrome 14.0.797.0 Dev (@ june, 2011), a new alpha build of their web browser for Mac, Windows, and Linux users. Also available for Chrome Frame users, the new release brings an updated V8 engine, and a bunch of platform specific tweaks, including one for Mac users.

Want to see what's happening quickly, then you want the Dev channel.  The Dev channel gets updated once or twice weekly, and it shows what we're working on right now.  There's no lag between major versions, whatever code we've got, you will get.  While this build does get tested, it is still subject to bugs, as we want people to see what's new as soon as possible.

Canary is an attempt to create a very lightweight Java desktop application to monitor and update the Twitter online "What Are You Doing" service. Its main advantages are that:

• it's lightweight (some effort has been made to keep it that way) so one does not need to load a fat browser to monitor twitter;
• it only uses POJOs (Plain Old Java Objects);
• it's open source so one can modify the hell out of it;
• Fast start-up
  Google Chrome launches in a snap.
• Fast loading
  Google Chrome loads web pages quickly.
• Fast search
  Search the web right from the address bar.

Canary was designed as a tutorial project and hence is fairly rough and unsophisticated at this point. More enhancements are planned for the future, due right about the time Vista becomes a robust and viable operating system.
