The default of 32 remains the same. This parameter also affects scroll acceleration linearly. A second part of this change is a tightly coupled modification to the scroll acceleration. Previously, scroll acceleration could be reset without lifting the scroll finger. This is rather unintuitive and hard to control in the case where a user wants faster scrolling, but wants to hold the scroll touch for longer than a moment. Note that scroll acceleration levels are now 1-7, where 7 is slowest. In the previous implementation, there were 8 levels defined, but it was impossible to start at the slowest level. In order to keep the default scroll speed unchanged, only 7 levels are used now.
