Transition of RubyGems Repository Ownership

The Ruby community has experienced some turbulence
of late after Ruby Central took
control of the GitHub repositories for a number of projects
including RubyGems
and Bundler. Those projects have historically been developed
separately from Ruby itself. They are now being put under the
control of Ruby's core team, according to Ruby creator Yukihiro
Matsumoto (a.k.a. 'Matz'):

To provide the community with long-term stability and continuity,
the Ruby core team, led by Matz, has decided to assume stewardship of
these projects from Ruby Central. We will continue their development
in close collaboration with Ruby Central and the broader
community.

Ruby Central has also issued a statement.
