+description: "Apache Answer 2.0.2 improves AI chat with reasoning content support, adds flexible email notification settings, hardens authentication and permissions, and fixes a round of short-link, API, and packaging issues."
+---
+
+We're pleased to announce **Apache Answer 2.0.2**, a focused patch release that improves the AI chat experience, adds more flexible email settings, and tightens security across authentication, permissions, and content handling.
+
+You can download the release from the [Apache Answer download page](https://answer.apache.org/download) or view the full details on the [GitHub release page](https://github.com/apache/answer/releases/tag/v2.0.2).
+
+---
+
+## ✨ Highlights
+
+### AI Reasoning Content Support
+
+Reasoning models often expose their chain-of-thought before delivering the final answer. Apache Answer now preserves that reasoning content in AI conversation records and the chat UI, so follow-up rounds retain the full context.
+
+- **Add reasoning content support in AI conversation records and chat UI** ([#1530](https://github.com/apache/answer/pull/1530)) by [@hgaol](https://github.com/hgaol)
+
+### Optional Email Verification
+
+For deployments that do not require mandatory email confirmation, administrators can now disable email verification directly from site settings, making onboarding smoother for internal or trusted environments.
+
+- **Allow disabling email verification from site settings** ([#1540](https://github.com/apache/answer/pull/1540)) by [@AsyncAssassin](https://github.com/AsyncAssassin)
+
+### Configurable New-Question Email Intervals
+
+New-question email notifications now support interval-based delivery, and the email throttle has been moved to a dedicated worker with a configurable queue.
+
+- **Add interval support for new question email notifications** ([#1545](https://github.com/apache/answer/pull/1545)) by [@AsyncAssassin](https://github.com/AsyncAssassin)
+- **Move new question email throttling to a dedicated worker and make the email queue configurable** by [@AsyncAssassin](https://github.com/AsyncAssassin)
+
+### Graceful Panic Recovery
+
+Unexpected panics are now caught earlier and handled more gracefully, reducing the chance of a single failure tearing down an entire request.
+
+- **Add recovery middleware to handle unexpected panics more gracefully** ([#1537](https://github.com/apache/answer/pull/1537)) by [@hhc7](https://github.com/hhc7)
+
+### Safer External Login
+
+Connector sign-in flows are now more robust against incorrect account binding, and API key access is cleaned up when roles or accounts change.
+
+- **Prevent incorrect external login account binding during connector sign-in flows** by [@LinkinStars](https://github.com/LinkinStars)
+- **Remove stale administrative API key access after role or account changes** by [@LinkinStars](https://github.com/LinkinStars)
+
+### Build & Packaging Update
+
+- **Update Docker and CI build flow to use Buildx and Go 1.25** by [@LinkinStars](https://github.com/LinkinStars)
+
+---
+
+## 🔒 Reliability and Security Improvements
+
+Alongside the release note items, the changes between **v2.0.1** and **v2.0.2** also harden several important areas:
+
+- **Short link fixes**: editing questions and accepting answers now work correctly when short links are enabled ([#1541](https://github.com/apache/answer/pull/1541), [#1554](https://github.com/apache/answer/pull/1554))
+- **License compliance**: added the missing license entry for `mozillazg-go-unidecode` ([#1552](https://github.com/apache/answer/pull/1552))
+- **Header hardening**: `Accept-Language` parsing now rejects malformed oversized headers
+- **Revision audit permissions**: approve and reject actions now use aligned permission checks
+- **Avatar ownership**: avatar cleanup now enforces ownership checks when updating profile images
+- **Content visibility**: deleted or pending answers are restricted in answer and MCP retrieval paths
+- **Error handling**: JSON 500 rewriting is limited to API routes and avoids rewriting already-flushed responses
+- **URL slugs**: non-Latin titles now generate pragmatic ASCII slugs instead of falling back to `/topic` ([#1526](https://github.com/apache/answer/pull/1526))
+
+These changes make 2.0.2 a recommended upgrade for teams already running 2.0.0 or 2.0.1.

+
+## ✨ 本次更新亮点
+
+### AI 推理内容支持
+
+推理模型通常会在给出最终答案前展示思考过程。Apache Answer 现在会在 AI 对话记录和聊天界面中保留这部分推理内容，让多轮对话能够保留完整的上下文。
+
+- **在 AI 对话记录和聊天界面中支持推理内容** ([#1530](https://github.com/apache/answer/pull/1530))，感谢 [@hgaol](https://github.com/hgaol)
+
+### 可选邮箱验证
+
+对于不需要强制邮件确认的内部或受信任环境，管理员现在可以直接在站点设置中关闭邮箱验证，简化用户入驻流程。
+
+- **支持在站点设置中关闭邮箱验证** ([#1540](https://github.com/apache/answer/pull/1540))，感谢 [@AsyncAssassin](https://github.com/AsyncAssassin)
+
+### 可配置的新问题邮件通知间隔
+
+新问题邮件通知现在支持按间隔发送，同时邮件限流也已迁移到独立 worker，并支持配置邮件队列。
+
+- **新增新问题邮件通知的间隔发送支持** ([#1545](https://github.com/apache/answer/pull/1545))，感谢 [@AsyncAssassin](https://github.com/AsyncAssassin)
+- **将新问题邮件限流迁移至独立 worker，并支持配置邮件队列**，感谢 [@AsyncAssassin](https://github.com/AsyncAssassin)
+
+### 更优雅的 Panic 恢复
+
+新增 recovery 中间件，可以更早、更优雅地捕获意外 panic，降低单个失败拖垮整个请求的风险。
+
+- **新增 recovery 中间件以更好地处理 HTTP 请求中的意外 panic** ([#1537](https://github.com/apache/answer/pull/1537))，感谢 [@hhc7](https://github.com/hhc7)
+
+### 更安全的外部登录
+
+连接器登录流程现在能更好地防止错误的账号绑定，同时在角色或账号变更后会清理过期的管理员 API Key 权限。
+
+- **防止连接器登录流程中的错误外部账号绑定**，感谢 [@LinkinStars](https://github.com/LinkinStars)
+- **在角色或账号变更后移除过期的管理员 API Key 权限**，感谢 [@LinkinStars](https://github.com/LinkinStars)
+
+### 构建与打包更新
+
+- **Docker 与 CI 构建流程升级为 Buildx 与 Go 1.25**，感谢 [@LinkinStars](https://github.com/LinkinStars)
+
+---
+
+## 🔒 稳定性与安全性增强
+
+除了 release note 中列出的内容之外，从 **v2.0.1** 到 **v2.0.2** 的代码改动还覆盖了几项很重要的底层修正：
+
+- **短链接修复**：开启短链接后，编辑问题和采纳回答现在都能正常工作 ([#1541](https://github.com/apache/answer/pull/1541), [#1554](https://github.com/apache/answer/pull/1554))
+- **许可证合规**：补充了 `mozillazg-go-unidecode` 缺失的许可证声明 ([#1552](https://github.com/apache/answer/pull/1552))
+- **请求头加固**：`Accept-Language` 解析现在会拒绝畸形超长请求头
+- **修订审核权限**：采纳与拒绝操作的权限校验现在保持一致
+- **头像所有权**：更新头像时会强制执行所有权检查并清理旧头像
+- **内容可见性**：在回答与 MCP 检索路径中限制已删除或待审核回答的可见性
+- **错误处理**：JSON 500 重写仅作用于 API 路由，并避免在响应已刷新后重写
+- **URL Slug**：非拉丁标题现在会生成实用的 ASCII slug，而不是回退到 `/topic` ([#1526](https://github.com/apache/answer/pull/1526))
+
+如果你已经在使用 **2.0.0** 或 **2.0.1**，我们建议尽快升级到 **2.0.2**。
