3011 Security Updates

We have a customer who has failed their Cyber Essentials as the assessor is saying their Mikrotik Routerboard 3011 is end of life and needs replacing.

My understanding is that this is nonsense as the device is still getting firmware updates, but I can't find anywhere that states that explicitly so it's going to be difficult to convince the assessor. Their view is the website listing it as discontinued means it needs to be replaced.

Is anyone aware of any official list on which devices are still receiving security updates?
