Freepbx not updating automatically anymore

We are running FreePBX 15.0.37.8 ‘VoIP Server’, and it has served us great. I had it set up for automatic updates on the weekend, and that worked fine, until it seemingly stopped. I now gbet emails that say:

Transaction Summary : No packages marked for update

Also get a second email every time that says:

endpoint has been automatically upgraded to fix security issues:
SEC-2023-001
restapps has been automatically upgraded to fix security issues:
SEC-2023-001, SEC-2021-013
pms has been automatically upgraded to fix security issues: SEC-2022-001

But when I run the update manually, there are typically some updated modules, or even the system. To my knowledge, nothing was changed.

What does that all mean? What could be the cause for not updating automatically anymore? I assume that the Endpoint fix was not applied, as I get this message every time.

15 is EOL, there hasn’t been module updates published in a long time, and there will be none going forward.
