Rails 3 beta has landed (and some dared install it on Windows !)

Check this tutorial if you want to install a fresh Rails 3 on Windows.

Remember to start using Ruby 1.9 as the old ruby 1.6 will be soon deprecated.

Note : at this point, a lot of gems and plugins are not adapted yet so you might want to wait before migrating existing apps and stick with rails 2.3.5 for your production apps. I recommend to start testing rails 3 right now (maybe in a virtual machine to avoid messing your actual environment).
