This means improvements across the board for animating in Blender, including solving papercuts such as the one dealt with in this patch: The ability to add keyframes Losslessly without affecting the animation by changing the curve paths!
This improvement is coming to Blender 2.91, alongside many others Sybren has committed in the past few weeks, including the patch allowing for snappier motion with the F curves. You can read all about the animation tools updates coming to Blender 2.91 in the link below.
