ruby "~> 3.2.x"

Ruby v3.2 is now generally available, and is the new default runtime version for Ruby based Builds and Serverless Functions. Additionally, Ruby v2.7 will be discontinued on December 7th, 2023.

  • Existing deployments that use Ruby v2.7 will continue to work
  • New deployments will use Ruby v3.2 by default, or if ruby "~> 3.2.x" is defined in the ‌Gemfile‍​‍​‍‌‍‌
  • After December 7th, 2023, new deployments that define ruby "~> 2.7.x" in the ‌Gemfile‍​‍​‍‌‍‌​‍‌‍‍‌‌‍‌‌‍‍‌‌‍‍​‍​‍​‍‍​‍​‍‌‍​‌‍‌‍‍‌‌​‌‍‌‌‌‍‍‌‌​‌‍‌‍‌‌‌‌‍​​‍‍‌‍​‌‍‌‍‌​‍​‍​‍​​‍​‍‌‍‍​‌​‍‌‍‌‌‌‍‌‍​‍​‍​‍‍​‍​‍​‍‌‍​‌‌​​‌‍‍‌​‍‌‍​‍‌‍​‌‍‌‍‌​‍‌‍‌‌‌‍‌​‌‍‍‌‌‌​​‌‍‌‌​‌​​‌‌‍​‌‍‌‌‌‍​‌‌‍‌‍‍‌‍​‌​‍‌‌‌‌‌​‌​​‍​​‌‌​‍​‌‍‍‌​​‌‌​‍‌‌‍‍‌‍‌​​‌‌‍‌‌‌​​‌‌‍‍‌​‍‌‍‌‌​​‌‌‍‌‌​‍​‍‌‌ will no longer build

Only the minor version (3.2) is guaranteed, meaning we will always use the latest patch version available within the minor range.
