-### FastGPT V4.7.1
+### FastGPT V4.8
 
-1. 新增 - 语音输入完整配置。支持选择是否打开语音输入（包括分享页面），支持语音输入后自动发送，支持语音输入后自动语音播放（流式）。
-2. 新增 - Pptx 和 xlsx 文件读取。但所有文件读取都放服务端，会消耗更多的服务器资源，以及无法在上传时预览更多内容。
-3. 新增 - 集成 Laf 云函数，可以读取 Laf 账号中的云函数作为 HTTP 模块。
-4. 修改 - csv导入模板，取消 header 校验，自动获取前两列。
-5. 修复 - 问题补全历史记录BUG
-6. [点击查看高级编排介绍文档](https://doc.fastgpt.in/docs/workflow/intro)

+本次更新的重点是对工作流 (高级编排) 进行了重构，使其更加简洁和强大。但由于新旧工作流机制有较大变化，尽管我们进行了一定的自动转换，仍有部分工作流需要您手动重建。请尽快更新到新版本，并对工作流进行必要的调试和重新发布。
+
+❗ 重要提示：
+1️⃣ 旧工作流更新后暂不失效，打开旧工作流会弹出自动转换提示，重新编排后点 “发布” 按钮发布新工作流
+2️⃣ 发布新工作流前，工作流自动保存功能暂不生效
+3️⃣ 应用和插件新增 version 字段，标识适用新/旧版工作流，以实现兼容
+
+✨ 新增功能亮点：
+1️⃣ 判断器：支持 if/elseIf/else 判断逻辑，工作流控制更灵活
+2️⃣ 变量更新节点：运行中可动态修改工作流输出变量或全局变量值
+3️⃣ 工作流自动保存和版本管理：自动保存修改，支持查看和回滚历史版本
+4️⃣ 工作流调试模式：更直观高效，可调试单节点或逐步执行，实时查看输入输出数据
+5️⃣ 定时执行应用：支持简单配置实现各种定时任务
+
+🛠️ 其他优化与修复：
+- 优化工作流节点连线方式，支持四向连接，易构建循环工作流
+- 显著提升工作流上下文数据传递性能
+- 简易模式下修改配置自动刷新调试框，免手动保存
+- 改进 worker 进程管理，支持 Token 计算任务分配，提高效率
+- 工具调用支持 string、boolean、number 数据类型
+- 完善 completions 接口对 size 参数限制
+- 重构 Node.js API 中间件和服务端代码
+- 对话记录长度调整为偶数，最大长度增至 50 轮，避免奇数导致部分模型不兼容
+- HTTP 节点出错将终止进程，避免异常影响
+- 修复工具调用名称不能以数字开头问题
+- 修复分享链接 query 参数缓存 bug
+- 修复工具调用和 HTTP 模块兼容性问题
