Dear IETF Community - By now many of you have received messages telling you about an upcoming header change in automated datatracker and announcement emails. The programmers involved in making this change and sending those emails are aware that the second email message - the "new" one - did not go out on either attempt. I have halted the automated jobs on their behalf until they are able to rectify the issues with the new email. Once they achieve a resolution, we'll conduct some testing, and make a final announcement. Until then, please ignore the two "old header" messages, and the absence of the "new header" messages. There is no need to worry, you did not miss anything. Thanks for your patience. Glen Glen Barney IT Director AMS (IETF Secretariat)
