"Fixed an issue in which avatars would sometimes slide after crouch-walking a short distance"
Crouch sliding has been in SL for such a long time that it is literally integrated into some games and movement systems. It is also extremely useful for minute positioning adjustments for photo taking, especially in places where the user is unable to rez. Having it removed when it was not even a widely requested or reported bug feels like something of a betrayal, and a large amount of the fun I got from the unique "feature" of it has been lost.
I would like to see at the very least it reinstated as a toggleable movement feature, similarly to "nimble" movement, if not rolled back entirely.
You can see where it was noted as having been fixed on a feedback thread that only received a handful of votes here; https://feedback.secondlife.com/server-bugs/p/crouching-causes-your-avatar-to-slide-around
