Check your spam folders. All updates went out via a new system yesterday.
Look at the distribution change @Jaxel just made upthread. He has now rectified this one IMHO. There is a web portal (he posted the link in this thread) you can access to download the updates. The emails will be to notify you there is something to retrieve.You use a strange way for downloading updates. Emailing is not like 20 years ago when all emails delivered even if it was spam. Now almost 90% of the incoming emails are blocking from mail servers especially the big ones like Gmail, Outlook, Yahoo etc. As an example the emailing for this update. Already 3 clients (plus me) wrote that they didn't got the email.
This is what I wrote. That I never got any email.
