Gemcutter will become rubygems.org and Rubyforge will eventually go away entirely:
So, what does this mean for RubyForge? The Ruby-specific functionality and data will be moved into RubyGems.org, and the parts that other hosting sites (GitHub, Google Code, SourceForge) can do better will be pruned away. Migration paths for those projects will be provided, we’re not throwing any switches without warning. RubyGems.org will not be gaining any “bloat” from rewritten RubyForge features.
Wow. Congrats to @qrush and the Rubyforge team for pulling this off so quickly. Also, it’s pretty cool to see Heroku hosting a major/official piece of Ruby community infrastructure.
