• MC-152728 Reverted fix - "The player continues sprinting when performing actions that slow them down"Developer's Note: After consideration, we have decided to revert this fix. While we do want to revisit these mechanics in the future, it's clear that these recent fixes alone didn't quite hit the mark and caused too many negative side effects for parkour, speedbridging, and movement in general
