先看升级的效果图
v1.2.0 有哪些新功能？?
主要的两个关键点:
✅ 循环控制新突破
新增的「退出循环」功能！现在可以精确控制流程中断节点，让复杂对话场景更丝滑~
✅ 检索速度开挂
通过全新ChildChunkApi接口，可提升知识库检索速度！
写在前面
我在本地dify做了什么？
拉取官方仓库 xx.git 修改端口 配置大模型(安装插件) 创建知识库 搭建应用 有对话记录
如果你也有跟我一样的操作，想保留上述的修改操作，并升级到Dify最新版。
可以直接按照教程【备份+升级+迁移】三步走，进行无痛升级，
Step1.备份
先停止服务
docker compose down
备份你clone下来后，修改的文件
比如 .env中修改了端口，所以.env文件要备份volumes文件夹保存的是你在Dify创建的知识库和应用等所有文件
cp docker-compose.yaml docker-compose.yaml.1.0.1
cp .env .env.1.0.1
tar -cvf volumes-1.0.1.tgz volumes
Step2.升级
拉取最新代码 & 启动新版本服务
git checkout main
git pull origin main
docker-compose up -d
Step3.迁移
笔者没有进行这步配置，好像也能访问插件。
如遇不能访问原插件，可进行以下步骤尝试。
3.1 进入 API 容器
找到dify-api的容器id: 7290d2e0b612
(base) PS D:\llm\workflow\dify> docker ps

进入 API 容器
## 输完第一行，回车就进入第二行了
(base) PS D:\llm\workflow\dify> docker exec -it 7290d2e0b612 bash
root@7290d2e0b612:/app/api#
3.2 插件迁移
此命令将提取当前环境中使用的所有模型和工具。
workers 参数将决定提取过程中的所使用的并行进程数，可根据需要进行调整。

升级后必做checklist
测试所有工作流节点 抽查历史对话记录 验证知识库检索速度 检查第三方插件连接
