Update error (An error occurred while parsing the update feed.)

Hello! I get this error trying to use built-in TempBox updater.
Probably the server is down.

TempBox version: 1.1
MacOS version: 13.5
MacBook Air 13"

Anyways, great app! I hope it will receive updates in future!

I found the updater url and yes, it has an error. Alternatively, I think it is better to handle updates using GitHub releases.
