+icon: 'upgrade'
+draft: false
+toc: true
+weight: 822
+---
+
+## Sealos 升级说明
+
+1. 在应用管理中新建一个应用，镜像为：registry.cn-hangzhou.aliyuncs.com/fastgpt/fastgpt-sandbox:v4.8.1
+2. 无需外网访问地址
+3. 部署完后，复制应用的内网地址
+4. 点击变更`FastGPT - 修改环境变量，增加下面的环境变量即可
+
+```
+SANDBOX_URL=内网地址
+```
+
+## Docker 部署
+
+可以拉取最新 [docker-compose.yml](https://github.com/labring/FastGPT/blob/main/files/deploy/fastgpt/docker-compose.yml) 文件参考
+
+1. 新增一个容器 `sandbox`
+2. fastgpt容器新增环境变量: `SANDBOX_URL`
+3. sandbox 简易不要开启外网访问，未做凭证校验。
+
+## V4.8.2 更新说明
+
+1. 新增 - js代码运行节点（更完整的type提醒，后续继续完善）
+2. 修复 - 新增的站点同步无法使用
+3. 修复 - 定时任务无法输入内容

-### FastGPT V4.8
+### FastGPT V4.8.2
 
-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
+- 新增 - 知识库重新选择向量模型重建
+- 新增 - 对话框支持问题模糊检索提示，可自定义预设问题词库
+- 新增 - js代码运行节点
+- 新增 - 外部文件源知识库: [点击查看文档](https://doc.fastai.site/docs/course/externalfile/)
+- 新增 - 内容提取节点增加完全提取成功输出
+- 新增 - HTTP节点增加错误输出，可以自行判断处理
+- 优化 - 插件输入的 debug 模式，支持全量参数输入渲染
