I have a 7530 rather than a 7530AX and am on 8.02. Is 8.20 likely to be rolled out to the 7530 or is it exclusive tio the AX?

I think it is very likely - they have both been part of the beta testing of v8.10, and have both been running here for some weeks. The AX has just probably been passed for release first.

Zen updated my Fritz!Box to 8.20 a couple of days ago.

No obvious problems except my max upload speed now seems to be around 120Mbps, where previously I was getting around 600Mbps (I'm on the Full Fibre 100 product). Though unfortunately I can't be certain that the change happened when 8.20 appeared.

Incidentally, when I first got Full Fibre 100 it was advertised as having an estimated download speed of 105Mbps (which is what I'm getting). For the current Full Fibre 100 product they now give an estimate of 155Mbps. Is there any chance that Zen might increase the speed for existing customers?

If you are supplied by CityFibre then yes - see this ISPreview article Zen Internet UK Gives Free Speed Boost to Some CityFibre Customers

Broadband ISP Zen Internet appears to have quietly begun a new programme of package upgrades (regrades) for some of their customers on CityFibre’s national Fibre-to-the-Premises (FTTP) network. The move essentially upgrades those on their 100Mbps (symmetric speed) plan to the faster rate of 160Mbps “at no extra cost“.

Excellent, thanks for that, though it looks like it may take months to happen!

v8.20 is now available for the 7530, some 3 months after the 7530AX, but several more beta versions were issued in that time for the 7530

v8.21 is now out which corrects a bug in 8.20
Mine wouldn't update from 8.02 (it failed twice) so I had to resort to downloading the update file from AVM myself.
So far, so good.

I applied the update, from 8.02 to my Frtiz!box 7530, last night. No problems with the update being applied, to be fair I had no connection issues on 8.02; don't use the built in Wi-Fi either.
To me it just looks like a UI tweak with the ability to monitor online activity of more devices.
Memory usage, since the update, has increased quite a bit though.
