The first release of the R buildpack after July 3, 2021 will no longer include R versions 4.0.x. These R versions will no longer be supported upstream.[1] Please migrate your R apps to supported versions of R before that time.

As always, the buildpacks team is happy to answer questions you may have about this deprecation in the #buildpacks Slack channel.
