Apologies for the lack of detail in my previous message, but the reason for the delay was an embargoed fix for https://ubuntu.com/security/notices/USN-4519-1.
I have now pushed RC image 2020-W38.
Due to the contents of the PulseAudio change, we believe we can release safely on Monday (September 21).
However, a change has been merged to
ubuntu-push during our freeze period, causing a rebuild. Since the last time ubuntu-push was rebuilt was a year ago, we are cautious around this component. It is possible that a change in one of its dependencies has caused a regression in its behavior on-device. During this period, please be extra-conscious of push notification receipt from apps like TELEports and FluffyChat.
I've run a variety of tests on devices using the pushclient example app in the store, so I'm fairly certain everything is fine. But please, watch this piece in particular.
