-- **`constructs` library upgrades**: Because `constructs` is a peer dependency, the `upgrade-main` script described above will _never_ increment its version; this will always need to be done manually by [editing](https://github.com/cdktf/cdktf-tf-module-stack/blob/b9939ad9f3bc6bc5bd7a4f348c953d776778506d/.projenrc.ts#L91) `.projenrc.ts`. This could _in theory_ be (semi)automated like some of our other upgrade workflows described above for things like CDKTF, Node, and JSII, but in practice we currently have no logic or criteria that governs when `constructs` should be updated; as such, creating a custom workflow for it felt like more effort than it's really worth.
 
 Also worth noting: Unlike many of our other Projen-based projects, this one does not have a script that automatically upgrades Node.js because this library does not enforce a `minNodeVersion`. If we did at some point want to start enforcing a `minNodeVersion`, we should copy over the `upgrade-node` script that our other Projen projects use.
