So you're on Linux and using Google Chrome browser, do you know you can switch between the developer (dev) and beta channels of Chrome. Say your using Ubuntu 10.04 (also known as Lucid Lynx), here's how to switch:
Switch from Beta to Dev: sudo apt-get install google-chrome-unstable
Switch from Dev to Beta: sudo apt-get install google-chrome-beta
Also, if you want to check whether a new dev version of Chrome is out, you can just repeat the same command: sudo apt-get install google-chrome-unstable. and if there's no new version, you'll get something like this back:
Reading package lists… Done
Building dependency tree
Reading state information… Done
google-chrome-unstable is already the newest version.
