There have been software errors in the delivery of this week's Tech News. MassMessage delivered 3 separate copies to some destinations, and 0 copies to other destinations. I've filed a task for the devs to investigate, at https://phabricator.wikimedia.org/T232379
There's not anything I can feasibly do en-masse to fix either of these problems, and many of the duplicates have already been individually fixed, so I offer my apologies on behalf of the software (as flawed as us humans!), and request that you please remove 2 of the duplicates where you find them, and copy the newsletter to pages where it is missing but should've been delivered.
We will also add a note about this problem into next week's Tech News.
Much thanks, Quiddity (WMF)
