Ruby apps now default to Node version 12.16.2 and Yarn version 1.22.4
Change effective on 13 July 2020
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 12.16.2 (was previously 10.15.3)
- Yarn version 1.22.4 (was previously 1.16.0)
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.
