The first release of the R buildpack after August 10, 2019 will no longer include R versions 3.4.x and 3.5.x. These R versions are no longer supported upstream. Please migrate your R apps to supported versions of R before that time.

Note: Unless you are manually specifying a version of R for the buildpack to use, or you have customized your R buildpack, no action is required.

Thanks,

Elliott Shanks, CF Buildpacks PM
