How to update Zigbee firmware?

I am dying to update my aqara P2 sensors which are matter over thread devices… when OTA updates for matter devices are on the pipeline?

He who seeks shall find.:man_shrugging:

I have a lot of Osram/ledvance devices. Some Z2, some Z3. Will they get OTA updates?

And can I zigbee2 device be updated to zigbee3?
