Looking to get the preview access with DoH\DoT on hardware version 1.26 or understanding of the update cycle of the Deco units. 

• What is the firmware update cadence?
• Why is there a difference between hardware versions 1, 1.26, and 1.6 - noticed that 1 & 1.6 are similar HW and 1.26 is different (why) 

Is there any models that are available to purchase that support Doh\DoT - can someone provide a list? 

Thanks in advance!
