Today's Postal Bulletin is located here.
This issue is another one that doesn't have changes that will affect our Presort software. The lone DMM revision is about "Bulk Proof of Delivery" with changes to DMM 503 (Extra Services), and those changes won't affect any mail sequencing.
A large portion of this bulletin is taken up with information about election and political campaign mail. Otherwise this issue is pretty much the standard fare - some new stamps (including "flags of our nation forever stamps"), some commemorative postmarks, some of the usual minor post office updates, along with the other miscellaneous things common to the bulletin.
