The SDK for Node.js buildpack includes new community Node.js runtimes.
This buildpack contains the following Node.js runtimes: v10.19.0, v10.20.1, v12.16.1, and v12.16.2. It is based on the community Node.js buildpack v1.7.17. The latest v10 runtime is the default runtime when one is not specified in the package.json. An existing application will not be affected by the new buildpack until you redeploy it. New applications will automatically use the new buildpack.
Additionally, the latest runtimes include OpenSSL vulnerability CVE-2019-1551. v8.x runtimes are no longer included in the SDK for Node.js buildpack.
