## 1.0.10
2024-08-25
* 移除extension实现机制
* 添加 getMapContentApprovalNumber / getSatelliteImageApprovalNumber（参见example#ShowMapPage）
* 添加 InfoWindowAdapter（参见example#CustomInfoWindowDemoPage）,结合 infoWindowEnable 和 BaseInfoWindowAdapter 自行实现具体逻辑
## 1.0.9
2024-08-24
* 设置地图语言，支持中文、英文（按SDK描述：1、不能和自定义地图样式同时使用；2、英文状态只在标准地图生效）
