The first release of the Node.js buildpack after March 01, 2019 will no longer include any versions of Node.js 9.11.x. These Node.js versions are no longer supported upstream [1]. Please migrate your Node.js apps to supported versions of Node.js before that time.

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