Automatic updates start with 0.4.0. On an older version, update once with
npm install -g adside@latest.adside update.
Turn it off
SetADSIDE_DISABLE_AUTOUPDATER=1 to turn the background update off. It is already off in CI.
If adside cannot update itself, for example because npm installs global packages in a folder only an administrator can write to, adside update says what to run instead.
