Updated to 1.0.6

Brought my HomePod from the office to my home to debug an issue I saw with my matter devices. I realised (too late) that my devices updated to 1.0.6 from being on the testnet.

Is there an official beta program and how stable is are versions uploaded to the testnet?

The betas have been very stable so far, but they are betas for a reason so proceed with caution. 1.0.6 has been flawless over here. I had a lot of the phantom blinks throughout my house and have not seen one since updating a few weeks ago.
