Bulldog (Death Scythe) got new custom hitbox and turning was also a bit improved.
Generally most of the previously unused fighters ex. Virage, Executioner, Phantom, Greyhound etc got some sort of improvement in 4.86, but as people are used to how these were before it might take a while before the impacts can be assessed.

Well reason why all that isn't written down is cause it least to people "feeling" more change than there is. For example if I say Titan turns a bit faster now (which it doesn't), then immediately someone would claim how insanely fast it is.
It shouldn't matter what was changed, only whether the ship is good/bad at something now.
