Ruby on Rails 1.1 RC1
I’ve added RoR 1.1 to portage. The numbering scheme they use upstream is the same as 1.0, except they tack on the SVN release number to the end, which in this case is 4008. Thus, you may be seeing an upgrade coming through portage as rails-1.0.0.4008.
I have slotted this release as 1.1, which means it will exist alongside your existing rails installation. However, your rails applications may want to make use of this new version when you reload them - as such, you may want to tie your existing runnings rails apps to the 1.0 that you’re currently using.
See this page for an explanation on how to lock your rails version.
Also see this page for an overview of some of the options you have to keep rails versions in your actual code base and not rely heavily on the system gems.
