Accumulated difference betwen 1.12.2 and latest version

Hi, @emlun ! 
It's been a few years since I integrated webauthn-server-core into my project. I'm currently using version 1.12.2. Everything works fine and stable, but I've been wanting to upgrade to the latest version. Could you please put together some general release notes from version 1.12.2 to the latest? I want to know if it's worth upgrading. I think it might be useful for more than just me.
