+**BREAKING CHANGE**
+
+Node 14 has already reached end of life as of April 2023, and Node.js 16 had its end of life date [brought forward to September 2023][node 16 eol], so in the interest of preventing another breaking change in 4 months time, we're pre-emptively dropping support for Node.js 16 in addition to Node.js 14.
+We've chosen to support Node.js versions from v18.12 onwards as this version was the first [Node.js 18 LTS release][node 18.12 release].
+
+Consider upgrading the Node.js version for your project across:
+
+- `.nvmrc`
+- `package.json#/engines/node`
+- `@types/node` package version
+- CI/CD configuration (`.buildkite/pipeline.yml`, `Dockerfile`, etc.)
