GPlates 2.3 released

I would like to update the GPlates package in Nixpkgs to version 2.3.0. However, for that I need a stable URL that I can download the source from. Do the URLs generated after filling out the form expire? I assume other Linux distributions face the same problem.

Also note that contacting people without their consent and collecting personal data is illegal in many jurisdictions. I thus ask you to reconsider the decision to make filling in that information mandatory.
