/{本次 **V2.2.0** 版本围绕[使用体验]、[账号安全]、[家校联动]、[学习管理]等方面进行多项优化与功能新增，具体更新内容如下：/}
工作录入新增**草稿箱功能**，录入内容自动暂存，录入途中临时退出、意外关闭页面，都不会丢失填写数据，有效避免重复录入，提升使用效率；
优化**多账号登录机制**，若同一手机号绑定多个账号，登录时需手动选择本次要登录的对应账号，区分账号使用，保障使用精准性；
全新上线**家校互动板块**，新增家长会、社群运营、线上家访特色功能，搭建高效家校沟通渠道，助力家校协同共育；
**成长中心**全面调整优化：成长中心入口迁移至工作台页面，升级全局搜索能力，章节内容改为结构化排版展示；优化视频播放逻辑与播放限制规则，同时新增学习过程监管功能，强化学习管控。
