If you're on Arch, the hack where you change the version number in the build_info.json file to the current version works this time. Sometimes that hack doesn't work but this week it does.
The discord pacman package sometimes takes up to 2 days to update to the newest version. I'm sure if I really wanted to get into it I could use wireshark to find out which ip addresses to block with the host file to make it stop refusing to let me use it without being on the latest version but that's a lot of effort for something that only might work.
Wouldn't blocking it break some other functionality? I wonder if you could have a more granular approach where given a payload and endpoint, return a predefined result.
That way you could isolate the "am I on the latest version" requeat specifically.
