Check it out: a Preview Release of Rails 2.0 was made available yesterday. Things are “almost finished” and this is an opportunity for folks (who haven’t been following edge closely) to get a taste of what’s new before the final release. To install the gem:
gem install rails --source http://gems.rubyonrails.org
Or you can freeze edge using the tag “rel_2-0-0_PR”. Make sure to check out that post (linked above) to read about all the good stuff.
Note that 1.2.4 will also be released prior to 2.0 and will include a variety of bugfixes as well as the final deprecation warnings for upgrading an application to 2.0. Big thanks to the whole core team (and all the contributors) for their excellent work.
