Check your spam folder, some of the email from the last private beta went in people's spam folder, so they never saw them. Either way it doesn't matter anymore since Docker for Mac and Windows is now public to use without the need of a code.
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.
Not sure what you mean about no message telling me to go get the bits today. There was no email saying that docker for mac/windows was made public, it was announced during the keynote at DockerCon (this morning), and a blog post went out.
Before we made it public, everyone who had signed up for the beta had an invite sent to them, and there was no one left in the queue.
