Spine: 3.8.99

Version is the final minor revision of the 3.8 branch. Typically, a .99 build indicates a "finalization patch" before a major version shift. In this case, 3.8.99 served as the bridge before Spine 4.0 beta. It is considered the most stable version of the 3.x generation, having received all backported bug fixes and performance patches without introducing the breaking changes of 4.0.
