Reading the patchnotes and came across this bit...

Fix surface horizontal velocity being incorrectly calculated.

Does this imply any fix to the bug that makes some spaceplanes roll when pitching?

[selfish_meme]

It did not seem to, I think that when your readout changes between surface and orbit there used to be a bit of difference in speed, maybe thats it.

[Red Iron Crown]

I think that refers to the F3 report at the end of the mission showing an incorrect maximum surface speed.

The orbit and surface speed should almost always be different.

Could be linked to a similar bug with KER's horizontal and vertical velocity readings.

I don't know if KER calculates these values itself or just takes them from the game, but if it's the second option, it's a good thing this is fixed.

A bug in horizontal speed calculation was fixed, as was a the 'cap' of 750m/s in the F3 flight log window.

I thought that said "reading the potatoes".
