Ruby at a glance
Ruby is a widely used programming language, notably behind Ruby on Rails and much tooling and automation. The Ruby core team ships a new minor version yearly, each maintained with bug and security fixes for a few years, plus security releases for the interpreter and standard library.
For admins Ruby is usually a runtime beneath an application (often Rails), whose requirements set the version. Apply security fixes promptly by moving the Ruby version in servers, containers and CI, and keep the end-of-life date of your minor version in view — running an unsupported Ruby is a common exposure. Version managers (rbenv, rvm) keep multiple Rubies in parallel; on updates, check the application and its native gems. The gem dependencies carry their own supply-chain risk — audit them (bundler-audit helps). Test the app before moving a major Ruby version. Patchletter surfaces new Ruby releases.
