I installed MIAB on Ubuntu 18.04.6 LTS in June using Linode.
Now I see:
“A new version of Mail-in-a-Box is available. You are running version v57a. The latest version is v60.1. For upgrade instructions, see https://mailinabox.email.”
I am assuming I need to create a new MIAB on Ubuntu 22, backup my old MIAB and move it too new one?
Are there any security updates lacking in v57a that I need to update immediately or can I wait a while on this?
