Previously the softbody strength property was controlling the strength of the constraints that pin all vertices to the original location. This was causing problems when the forces were trying to deform the vertices too much, like when using gravity or grab brushes. Now softbody is implemented with plasticity, which creates constraints to a separate coordinates array. These coordinates are deformed with the simulation, and the plasticity parameter controls how much the simulation moves the coordinates (plasticity 0), or the coordinates move the simulation back to its previous position (plasticity 1). This creates much better and predictable results and adding softbody plasticity to the brushes can increase its control and the stability of the simulation.
