### 亮点
- Agent 和 Codex 运行时恢复更加稳定：子代理保持 cwd/工作空间分离，钩子上下文保持提示词本地化，会话锁在超时中止时释放，而活动的 OpenClaw 锁在清理后仍存在，避免了过期的重启延续，且 Codex 应用服务器/辅助程序故障不再破坏共享运行时状态。（#87218, #86875, #87409, #87399, #87375, #88129）
- 频道投递和会话身份在出站插件钩子、Matrix 房间 ID、iMessage 反应/批准、Slack 最终回复、Discord 恢复工具警告、运行时配置消息操作、WhatsApp 配置文件认证根、Telegram 轮询以及 Microsoft Teams 服务 URL 信任检查中变得更加安全。（#73706, #75670, #87366, #87451, #87334, #84535, #82492, #83304, #87160）
- 移动端和聊天界面得到了更广泛的更新：iOS Pro 界面、托管推送中继默认设置、实时 Talk 选项卡播放、Gateway 聊天传输、入门引导、Talk 权限、WebChat 重连投递以及会话选择器行为现在在重连和空搜索中保留更多状态。（#87367, #87531, #87682, #88096, #88105）感谢 @ngutman 和 @BunsDev。
- 浏览器、频道和自动化输入更加严格：浏览器工具超时、视口/标签索引、Gateway 端口、cron 重试处理、Discord 组件 ID、模式数组引用、Telegram 回调页面以及频道进度回调现在更早地拒绝格式错误的值，并保留预期的投递上下文。（#82887）
- 提供商、媒体和文档覆盖范围扩大，新增 Claude Opus 4.8、Fal Krea 图像模式、NVIDIA 特色模型、MiniMax 流式音乐响应、加密 PDF 提取、语音模型目录、GitHub Copilot 代理运行时支持，以及 Codex Supervisor 插件路径用于委托的 Codex 工作流。（#87845, #87890, #80775, #84764, #87751, #87794）
- CLI、认证、诊断和提供商路径更快失败并更清晰地恢复：拒绝格式错误的数字/版本选项，忽略工作区 dotenv 提供商凭据，心跳默认值、OAuth/令牌生命周期和本地服务启动请求受限，代理认证健康标签更清晰，旧版 `api_key` 认证配置文件迁移到规范形式，重启指导可操作。（#87398, #86281, #87361, #88133, #83655, #87559, #88088, #85924）感谢 @vincentkoc 和 @giodl73-repo。
- 插件和 Gateway 热路径减少重复工作，同时保持缓存正确性，涉及安装记录、配置 JSON 解析、工具搜索目录、会话存储、清单模型行、自动启用插件配置、浏览器令牌、查看器资产以及发布拆分的外部插件包。（#86699）
- 发布、质量保证和端到端验证现在对更多日志、工件、工作台和跨操作系统等待进行限制，使失败的任务生成证据而不是挂起或虚假通过。

### Highlights
- Agent and Codex runtime recovery is steadier: subagents keep cwd/workspace separation, hook context stays prompt-local, session locks release on timeout abort while live OpenClaw locks survive cleanup, stale restart continuations are avoided, and Codex app-server/helper failures no longer tear down shared runtime state. (#87218, #86875, #87409, #87399, #87375, #88129)
- Channel delivery and session identity got safer across outbound plugin hooks, Matrix room ids, iMessage reactions/approvals, Slack final replies, Discord recovered tool warnings, runtime-config message actions, WhatsApp profile auth roots, Telegram polling, and Microsoft Teams service URL trust checks. (#73706, #75670, #87366, #87451, #87334, #84535, #82492, #83304, #87160)
- Mobile and chat surfaces got a broader refresh: the iOS Pro UI, hosted push relay default, realtime Talk tab playback, Gateway chat transport, onboarding, Talk permissions, WebChat reconnect delivery, and session picker behavior now preserve more state across reconnects and empty searches. (#87367, #87531, #87682, #88096, #88105) Thanks @ngutman and @BunsDev.
- Browser, channel, and automation inputs are stricter: Browser tool timeouts, viewport/tab indices, Gateway ports, cron retry handling, Discord component ids, schema array refs, Telegram callback pages, and channel progress callbacks now reject malformed values earlier and preserve the intended delivery context. (#82887)
- Provider, media, and document coverage expands with Claude Opus 4.8, Fal Krea image schemas, NVIDIA featured models, MiniMax streaming music responses, encrypted PDF extraction, voice model catalogs, GitHub Copilot agent runtime support, and a Codex Supervisor plugin path for delegated Codex workflows. (#87845, #87890, #80775, #84764, #87751, #87794)
- CLI, auth, doctor, and provider paths fail faster and recover more clearly: malformed numeric/version options are rejected, workspace dotenv provider credentials are ignored, heartbeat defaults, OAuth/token lifetimes, and local service startup requests are bounded, agent auth health labels are clearer, legacy `api_key` auth profiles migrate to canonical form, and restart guidance is actionable. (#87398, #86281, #87361, #88133, #83655, #87559, #88088, #85924) Thanks @vincentkoc and @giodl73-repo.
- Plugin and Gateway hot paths do less repeated work while preserving cache correctness for install records, config JSON parsing, tool search catalogs, session stores, manifest model rows, auto-enabled plugin config, browser tokens, viewer assets, and release-split external plugin packages. (#86699)
- Release, QA, and E2E validation now bound more log, artifact, harness, and cross-OS waits so failing lanes produce proof instead of hanging or false-greening.
### Changes

- Diffs: split the default language pack and expand default Diffs language coverage while keeping the host floor aligned. (#87370, #87372) Thanks @RomneyDa.

- Docs: clarify Codex computer-use setup, paste-token stdin auth setup, macOS gateway sleep troubleshooting, native Codex hook relay recovery, container model auth, install deployment cards, device-token admin gating, CLI setup flow compatibility, Notte cloud browser CDP setup, and backport targets. (#87313, #63050, #87685) Thanks @bdjben, @liaoandi, and @thewilloftheshadow.

- Codex/GitHub: add the GitHub Copilot agent runtime and the Codex Supervisor plugin package.
- Plugins: externalize GitHub Copilot and Tokenjuice as official install-on-demand plugins with npm and ClawHub publish metadata.
- Workboard: add agent coordination tools for tracking and handing off active agent work.
- Discord: show commentary in progress drafts so live Discord runs expose useful in-progress context. (#85200)
- Plugin SDK: add a reply payload sending hook for plugins that need to deliver channel-owned replies and flatten package types for SDK declarations. (#82823, #87165) Thanks @piersonr and @RomneyDa.
- Policy: add policy comparison, ingress-channel conformance, and sandbox-posture conformance checks. (#85572, #85744, #86768)

- File transfer: handle late tar stdin pipe errors after archive validation or unpacking has already settled.
- Performance: trust install-record caches between reloads, prefer native JSON parsing, reuse unchanged tool-search catalogs, reuse gateway session and plugin metadata paths, skip unchanged store serialization, patch single-entry session writes, add precomputed session patch writers, reduce store clone allocations, cache manifest model catalog rows and auto-enabled plugin config, avoid full session snapshots for entry reads, defer configured Slack full startup, prefer bundled plugin dist entries, and slim current metadata identity caches. (#87760)
