With the release of the MR 31.1.1 beta firmware, I see a couple of new features and one missing feature that I thought would be in this version.
The first new feature is the option to support Assa Abloy Door Locks (https://www.assaabloy.com/pl/en/solutions/products/digital-access-solutions/aperio)
It looks like you have to make a choice between BLE, ESL, MQTT and Door Lock support,

The second new feature is in the radio profiles and you can now choose between 802.11ax and 802.11be support for AP models that support it. 802.11be is WiFi7, so I think Cisco just revealed that new AP models are not too far away from being released, maybe at a certain large Cisco conference in a few weeks?

The feature that I thought would be in this version but is still not there is AFC support for 6 GHz standard power.
So let the speculation begin on WiFi7.
