抱歉，添麻烦了。 主干版本不向后兼容。 但是，您可以在设置中更改Spine版本，请参阅http://zh.esotericsoftware.com/spine-settings
如果您是在3.8.72中创建的项目，并且需要降级到3.7.x，请按照以下说明查看JsonRollbackTool：http://esotericsoftware.com/forum/Spine-editor-and-runtime-version-management-6534
Sorry for the trouble. Spine versions are not backward compatible. You can however change the Spine version in the settings, see 设置 - Spine用户指南
If you created a project in 3.8.72 and need to downgrade to 3.7.x, please look into the JsonRollbackTool as described here: Spine editor and runtime version management
