# - Bumping the *minimum* required Node version? You must bump:
#   1. package.json -> engines.node
#   2. package.json -> devDependencies.@types/node
#   3. tsconfig.json -> {target, lib}
#   4. .github/workflows/ci.yml -> node-version
# - Bumping the *maximum* tested Node version? You must bump also: publish.yml
