The screenshot you posted, I believe was the time that the notice would expire and stop appearing on the top of the page.
This. Every time Kes posts regarding the migration/update, the message has a one month range. The post disappears on that expiration date.
That might be the 'intent'... but you're not thinking of the 'loophole' ...
Can't say you didn't know it would be a month when the date was right there for all to see...
'But, but, but, that was a post expiration date'...
Well, you should have know the real purpose sucka.
