gmail is beta no more

I've just received an email from gmail:

Thanks for signing up to be updated on the latest Gmail happenings. We hope it's been worth the wait, because we're excited to finally offer you an invitation to open a free Gmail account!

Since the email that I gave them now feeds into my gmail account, I received this invitaiton about gmail via gmail, but gmail was nice enough to tag my gmail invite as spam.

I assume that this means that gmail is invite-only no more. Though I still have 50 invitations available to me.

Update: someone should tell Google, though, as the graphic still reads beta...
