What is Spine 3.8.99?
It is the runtime library version that loads and plays animations exported from Spine Editor 3.8.99. The runtime and editor major/minor numbers must match exactly (e.g., 3.8.xx runtime with 3.8.xx exported data). This version is the final polished state of the 3.8 series, focusing on bug fixes and performance rather than new features.
Engine Compatibility: Perfect for older Unity, Cocos2d-x, or Phaser projects that haven't updated their runtimes yet.
