+Strict semver is a little complicated, as TypeScript itself does not adhere to semver. So our "best effort" policy is:
 
 - Each update to the minimum Node target (e.g., Node 18 to Node 20), or a change to a major compiler output option
   (e.g. `module`, `target` or `moduleResolution`) will result in a new major version of this module.
   We coordinate this with whatever the latest LTS version of Node is currently supported by Amazon Lambda,
   Google Cloud Functions, and Azure Functions.
-- Each new "major" version of Typescript (e.g. `4.2.x` to `4.3.x`) will result in a new minor version of this module.
-- A new minor update of Typescript (e.g. `4.3.1` to `4.3.2`) _may_ result in a patch, in
-  a situation where a specific need or issue requires setting a new minimum version of Typescript.
