[The Ruby Core Team Takes Ownership of the RubyGems Repo](https://www.ruby-lang.org/en/news/2025/10/17/rubygems-repository-transition/) — After several weeks of confusion, the RubyGems/Ruby Central situation reaches a conclusion with ownership of the RubyGems and Bundler repos shifting to the Ruby core team.

On _X_, Rich Kilmer, one of RubyGems' co-creators [has celebrated this outcome.](https://x.com/rich_kilmer/status/1979167654867873898)
