More than a rumor I think. *My recollection is that it was

It would be interesting to know what they did and if there is anything
used for gust filtering etc.

The accelerometer (or one axis of it) is used for the slow flight
warning, as can be demonstrated by playing around with the glider near
the low-speed threshold.

That may be true but, from my experience, they didn't make it work
very well. I have to set my slow alarm threshold well below 1 g stall
to stop it being a nuisance while thermalling. I like to crank it up
tight in our southwest thermals. With that setting though it is
useful as the 28 climb rate really falls if if flown too slow.
