Before fetching releases for Cataclysm DDA, the launcher could check the Catapult Github page for any new updates and automatically update after asking the user. There could also be a switch in Settings to enable/disable this feature.

I always found it funny how the launcher could update CDDA/CBN but not self-update.

Honestly, I don't even know how to approach self-updating. Catapult is one self-contained executable, how would it replace itself and then restart itself?

How would you approach this?

My first thought would be to spawn an updater child process to a temporary directory. From there you would terminate the parent process, download the zip, extract and overwrite in the existing directory. Run the catapult launcher again and terminate the child process.
