Ruby apps now default to Node version 16.13.1 and Yarn version 1.22.17

Change effective on 16 December 2021

Applications using the heroku/ruby buildpack that do not have a version of Node installed by another buildpack (such as the heroku/nodejs buildpack) will now receive:

  • Node version 16.13.1 (was previously 12.16.2)
  • Yarn version 1.22.17 (was previously 1.22.4)

These versions and instructions on how to specify a specific version of these binaries can be found on the installed binaries section of the Heroku Ruby Support page.
