Microsoft announced that the Exchange Online Management PowerShell module is now generally available. This is the version with the nine faster, more stable cmdlets like Get-ExoMailbox. During the preview, the cmdlets got some significant testing. Microsoft says that they were run 150 million times during May. This sounds like a lot, but we don't know because Microsoft won't say how much PowerShell is used with Exchange Online.
