Nobody tested it yet. Feel free to try and report results here.

Being a curious cat, I tried to upgrade to Rails 2.1 with "gem update rails" command in my development environment.
When the upgrade finished, Redmine didn't start in the first place. Then I tried to start console to see what's wrong, it told me to upgrade boot.rb.

# ./script/console
Loading development environment (Rails 2.1.0)
Your config/boot.rb is outdated: Run "rake rails:update".

After running rake command, everything seemed to work OK.

A branch was open for Rails 2.1 compatibility but the current trunk (r1524) is not compatible.
Fixes will be merged in trunk as soon as possible.

I think Rails 2.1 breaks the Engines plugins. We had problems with other projects as well ...

The engines plugin should work with Rails 2.1 - check the development on github (, and post any bug reports to the lighthouse (

In addition to "rake rails:update", I had to comment out Rails version in config/environment.rb. And then I got the following error:

What could be missing ?
