It seems to me that for April the 10th the 'Very Hard' and the 'Super Hard' were swapped

What leads you say that?

I tried both puzzles, and the solutions for both came quicker than
average, and I wouldn't say I found one harder than the other.
Sometimes it just goes that way. (I was using "show squares with a.."
feature, and allowed myself multiple uses of the "auto pencil marks"
feature.)

I think the difference between the two gradings is the techniques
required to solve them, so a "super hard" puzzle shouldn't be solvable
with just the "very hard" techniques - are you saying you think that it
was? I don't really think about the techniques I use, and have the same approach regardless of the puzzle grade. I don't instantly recognise
the names of most the techniques listed on the help page!

The answer button used to open a new tab with all the required steps set
out in detail. Now it justs populates the grid with the solution.
That's a shame.

At first I couldn't solve the "very hard" without using "super hard" techniques, and didn't need any "super hard" techniques to solve
the "super hard". I've just done the "very hard" one again, and
didn't need any "super hard" this time. Obviously overlooked
something. From time to time the "super hard" ones don't need
any of the extra "super hard" techniques.

The last point you make is a little surprising. The puzzles are
computer generated, so it would be straight forward for the generator to
know whether a puzzle can be solved using just the techniques for "very
hard" puzzles. It would just ask is this solvable using "very hard"
techniques and if "yes", then the puzzle is at most "very hard". (It
can then ask if the puzzle is solvable using just "hard" techniques, and
if so then "very hard" is the correct grade, and so on. Simples! :)

Of course, there could be bugs in the solver, or maybe it doesn't do the
checks I suggested but that would be a lot of work to veryify...
