Sometimes things are just off by a day, and then go back to normal.
I would want to see a change over a couple of weeks at least before thinking
they have changed their pattern.
This week it was Tue and Fri, but I would bet it will be back to normal next
week, but who knows?
Of course the last time I checked last night it was just after 11:00 pm CST
USA, if they released the 1.89.901.0 update to the channels before midnight
it could still be considered a Thursday release and of course that depends on
what time zone you use as your base, CDT, UTC, PDT, etc
