No messages (and I applied via two accounts for two different platforms). No message telling me "go get the bits!" today. And nothing in spam folders.
But yet another blog post asking me to sign up for yet another private beta... ugh.
EDIT to add: As polite feedback--two separate requests, two separate Docker accounts, one Gmail and one corporate email address, and I did not receive any invite during the private beta nor notification today when it went public.
