Disabling Automatic Updates

I’m self-hosted and was under the impression no automatic updates would happen, but then two things happened:

  1. Today our host went to install a plugin and our site went down for nearly 20 minutes because, unbeknownst to him, the Discourse setup was no longer accepting variables with an ‘=’ sign, making us believe something must have changed since we last performed this operation.
  2. I noticed the dashboard was saying “Discourse last updated 17 hours ago” even though nobody from our team had initiated any updates. It had recently been saying it was out of date, too. We haven’t installed any updates since the beginning of April.
