The ".99" signifies that this is the final, most bug-fixed version of the 3.8 branch before the major transition to the 4.0 architecture, which introduced significant changes to animation curves and internal data structures. Key Features and Highlights of Spine 3.8.99 Spine 3.8.99

Before the overhaul in version 4.0, the Graph Editor in 3.8.99 was the primary tool for fine-tuning interpolation curves. It gave animators precise control over "ease-in" and "ease-out" functions, ensuring that movements felt organic and weighty rather than robotic.
