 ## FUNCTIONS\_EXTENSION\_VERSION
 
-The version of the Functions runtime that hosts your function app. A tilde (`~`) with major version means use the latest version of that major version (for example, `~3`). When new versions for the same major version are available, they're automatically installed in the function app. To pin the app to a specific version, use the full version number (for example, `3.0.12345`). Default is `~3`. A value of `~1` pins your app to version 1.x of the runtime. For more information, see [Azure Functions runtime versions overview](functions-versions.md). A value of `~4` means that your app runs on version 4.x of the runtime.
