I'd suggest either using Support_Updater or Blockland Glass for automatic updates, dealing with people stuck on older versions of add-ons is just annoying and unnecessary.
I've actually planned Blockland Glass already, I haven't done so yet because when I try to upload, their site says it's migrating or something so yeah whenever that's finished I'll do it there, I guess for now I'll find out how to do Support_Updater.Alright, so I've checked Blockland Glass' new website, and the Add-On won't pop up for my authentication, so I can't get it to work. And I have tried installing the latest version as well.
I can't fully understand how to use Support_Updater, and it seems you need to host it on your own website? I don't feel like messing with that, I'll just get it going on Blockland Glass whenever they fix the authentication issues. Yes, I did check Greek's manual, I read through it, and yeah no.
