Ruby is a simple and powerful object-oriented programming language, created by Yukihiro Matsumoto (who goes by the handle “Matz” in this document and on the mailing lists).
Ruby was first developed by Matz (Yukihiro Matsumoto) in 1993, and is now developed as Open Source. It runs on multiple platforms and is used all over the world especially for web development.
Please see the GitHub releases for further details. This version is a final release of Ruby 3.1 series. We will not provide any further updates including security fixes for Ruby 3.1 series. We recommend you to upgrade to Ruby 3.3 or 3.4 series. Download https://cache.ruby-lang.org/pub/ruby/3.1/ruby-3.1.7.tar.gz
We intend to release the latest stable Ruby version (currently Ruby 3.4) every two months following the most recent release. Following this release (3.4.4), Ruby 3.4.5 is scheduled for July, 3.4.6 for September, 3.4.7 for November, and 3.4.8 for January.
