Cessna 182S flaps

I just acquired my copy of the Cessna 182S PIH.
I was looking at the flaps/airspeeds page and noticed that the listings
are for zero, ten, twenty and full flaps.
When did Cessna start using the word FULL flaps to indicate the maximum
flap setting and just how many degrees is full flaps?

I went back to my 1982 182Q manual. It lists 0, 10, 20, 40 degree flap
settings.

Then I looked in my 1986 182R manual. It lists 0, 10, 20 and FULL.
I think, but am not certain, that full flaps on this model is still 40
degrees. (I will have to look at them tomorrow.) This manual is a new
edition, not an original 86 publication.

So now I am really courious. Has Cessna limited the flaps to 30 degrees
on the post 86 models?
