Our PCI compliance scanner (probably falsely) claims it's 2018-05-01.
The Wikipedia page: https://en.wikipedia.org/wiki/Debian_version_history
just says "May 2018".
clearly states "end of May 2018".
I'm treating the latter as the more reliable source.
My related question:
Is it likely for this date to still be moved forward or back?
Can it happen on a short notice (say less than a month)?
