Direct answer: The OpenClaw 2026.9 stable line shipped four releases in eight days — v2026.9.1 (Sep 3: Mermaid rendering, quick-start lane, personal skill libraries), v2026.9.2 (Sep 5: GPT-6 Astra), v2026.9.3 (Sep 8: updates rehearsed in isolation; Node 24.16+ now required) and v2026.9.4 (Sep 11: unified Plugins workspace, automatic rollback for compatible failed updates, prepared cloud sessions). Pi added GPT-6 Astra in 0.85.1; DeepSeek Harness shipped 0.1.5-rc.1 with V4.1-Flash support.
OpenClaw v2026.9.1: the September line goes stable
Official release highlights (stable channel):
- Diagrams in every chat: Mermaid blocks render as diagrams in the Control UI and the native macOS, iOS and Android apps, with enlarge previews and a mobile retry on render failure;
- From install to chat in one prompt: fresh installs (including
npx openclaw@latest) enter a quick-start lane that detects existing Claude Code or Codex logins and API keys, verifies them live and opens the web dashboard from a foreground Gateway; the full wizard remains as Custom setup; - Personal skill libraries on shared Gateways:
openclaw skills librarygives everyone a skill set separate from the workspace, with ZIP import and per-identity sharing or publishing on team Gateways; - Updates that leave you working:
openclaw updaterolls back the npm candidate when the post-update Doctor fails, preserves configuration and secret references across failed upgrades, and hands failures to built-in triage.
The official stable release was published on September 3. The site's upgrade tutorial covers the key changes in the 2026.9 line.
v2026.9.2 (Sep 5): GPT-6 Astra arrives, performance shored up
- GPT-6 Astra support:
openai/gpt-6-astraworks with an OpenAI API-key profile or an eligible ChatGPT/Codex account, with text and image input, Responses tool calls and supported reasoning controls; - Faster, more responsive chat: chat, dashboards and session interactions stay responsive while long transcripts and disk usage are processed, with durable history reads moved outside the Gateway event loop;
- Replies survive restarts: active, queued and delegated replies recover after Gateway restarts, with continuation instructions carried through compaction and retries.
v2026.9.3 (Sep 8): rehearse updates first, Node bar raised
- Safer updates: core and plugin changes are rehearsed in an isolated candidate state before activation; eligible 2026.9.2 migrations are supported and abandoned update records recover without stopping a healthy Gateway;
- ⚠️ Breaking — Node runtime: Node 24 needs ≥ 24.16.0, or Node 26 ≥ 26.1.0 (Node 26 recommended); Node 22, 25 and older 24.x/26.x builds are no longer supported — upgrade Node BEFORE OpenClaw to avoid SQLite text truncation;
- Skill Workshop persistence: skills live in one persistent agent-owned collection across workspaces, with full-instruction comparison;
- Sharing and meetings: publish a revocable read-only link to a session; a searchable meeting library lands in the Control UI (browse notes, full-text transcript search, Markdown/JSONL export);
- Provider accounts together: manage connected accounts and priority in Models settings.
v2026.9.4 (Sep 11): unified Plugins workspace, dependable rollback
- Recover from compatible failed updates: when schema and configuration checks prove rollback is safe, the previous package, command shim, service and pre-update configuration are restored; migration-bearing failures still require a verified pre-update backup;
- Plugins in one place: discover bundled and ClawHub plugins, install from the Control UI, and manage setup and access in a unified Plugins workspace;
- Prepared cloud sessions: start eligible Linux sessions from local projects or public GitHub repositories, with reusable snapshots built from the Control UI;
- GPT Image 2.5: pick the new Flare and Sunburst variants for image generation and editing via OpenAI or fal;
- Read-only config mode:
OPENCLAW_CONFIG_READONLY=1keeps OpenClaw from rewriting deployment-managed configuration.
Also: the June LTS line closed out with v2026.6.35 (Sep 10), the final Extended Stable release for June.
Pi 0.85.x: two versions in two days, GPT-6 Astra arrives
- v0.85.0 (Sep 4): persistent Claude thinking effort; fullscreen transcript controls; restorable in-memory sessions (
SessionManager.inMemory()for externally managed entries via the SDK); - v0.85.1 (Sep 5): GPT-6 Astra enters the model picker (OpenAI API keys and OpenAI Codex subscriptions); five-times-faster Alt+wheel scrolling in fullscreen; fixes SDK import failures caused by 0.85.0 accidentally shipping experimental code.
Pi's two-week model streak (DeepSeek V4 Flash Vision last week, GPT-6 Astra this week) keeps proving the kernel route's model agility — see the deep dive and product page.
Meanwhile: DeepSeek Harness 0.1.5-rc.1
After the 0.1.3-alpha line (Sep 4/7), DSH jumped to 0.1.5-alpha (Sep 8/9) and shipped the first 0.1.5 release candidate on Sep 10: a new DeepSeek-V41-Flash (deepseek-flash) adapter (default for new sessions, dynamic system-prompt updates that preserve the KV cache); web uploads of arbitrary file types with a multi-tab right Sidebar preview (Markdown, code, HTML, PDF, images); queueable, steerable subagent messages; rc.2 followed the same day with feedback and file-card polish. Per the official release notes, 0.1.5-rc.1 also upgrades the session data format to V3: supported older logs migrate with their originals preserved, and sessions upgraded to V3 do not support downgrade reads. All three self-hosted leaders moved this week; cross-check the comparison hub.

Direct answer: OpenClaw 的 2026.9 稳定线八天连发四版——v2026.9.1（09-03，全端 Mermaid 渲染/快速开始/个人技能库）、v2026.9.2（09-05，接入 GPT-6 Astra）、v2026.9.3（09-08，更新先隔离演练；Node 24.16+ 起步）、v2026.9.4（09-11，统一插件工作台/兼容失败自动回滚/预制云会话）。Pi 0.85.1 同步接入 GPT-6 Astra；DeepSeek Harness 发布 0.1.5-rc.1（V4.1-Flash 适配）。
OpenClaw v2026.9.1（09-03）：九月线转正
官方 release highlights（stable 渠道）：
- 每个对话都能画图：Mermaid 代码块在 Control UI 与 macOS/iOS/Android 原生应用中直接渲染为图表，支持放大预览，移动端渲染失败自动重试；
- 一条提示从安装到对话：全新安装（含
npx openclaw@latest）进入快速开始通道——自动检测已有的 Claude Code/Codex 登录与 API key、实时验证、从前台 Gateway 打开 Web 仪表盘；完整向导保留为 Custom setup； - 共享 Gateway 上的个人技能库：
openclaw skills library让每人拥有独立于工作区的技能集，支持 ZIP 导入，可在团队 Gateway 上按身份共享或发布； - 更新不再打断工作：
openclaw update在更新后 Doctor 失败时自动回滚 npm 候选、跨失败升级保留配置与密钥引用、失败交给内置 triage。
官方稳定版于 9 月 3 日发布。站内升级教程已覆盖 2026.9 线的关键变化。
v2026.9.2（09-05）：GPT-6 Astra 到场与性能补强
- GPT-6 Astra 支持：
openai/gpt-6-astra可通过 OpenAI API key 或符合条件的 ChatGPT/Codex 账户使用，支持文本与图像输入、Responses 工具调用与推理控制； - 更快更跟手的对话：长转录与磁盘用量处理期间保持聊天、仪表盘与会话交互响应，持久化历史读取移出 Gateway 事件循环；
- 回复跨重启存活：Gateway 重启后恢复活动/排队/委托中的回复，续写指令贯穿压缩与重试。
v2026.9.3（09-08）：更新先演练，Node 门槛提高
- 升级先演练：核心与插件变更先在隔离的 candidate 状态预演、通过后再激活；支持 2026.9.2 的合规迁移，健康 Gateway 不停机即可回收遗留更新记录；
- ⚠️ 破坏性变更——Node 运行时：Node 24 需 ≥24.16.0，或 Node 26 ≥26.1.0（官方推荐 Node 26）；Node 22/25 与旧 24.x/26.x 不再支持——先升 Node 再升 OpenClaw，避免 SQLite 文本截断；
- Skill Workshop 持久化：技能归入 Agent 名下的持久集合、跨工作区一致，可对比完整技能指令；
- 会话分享与会议库：可发布可撤销的只读会话链接；Control UI 新增可搜索的会议记录库（浏览笔记、全文搜索转录、导出 Markdown/JSONL 归档）；
- 多账户统一管理：Models 设置里管理已连接账户与优先级。
v2026.9.4（09-11）：插件统一工作台，回滚更可靠
- 兼容失败的更新自动回滚：模式与配置校验证明回滚安全时，恢复上一版本包、命令 shim、服务与更新前配置；含数据库迁移的失败仍需验证过的更新前备份；
- Plugins 工作台：Control UI 统一发现/安装内置与 ClawHub 插件，集中管理设置与访问；
- 预制云会话：从本地项目或公开 GitHub 仓库启动符合条件的 Linux 云会话，可构建可复用快照；
- GPT Image 2.5：经 OpenAI 或 fal 通道选用新 Flare/Sunburst 变体做图像生成与编辑；
- 配置只读模式：
OPENCLAW_CONFIG_READONLY=1阻止 OpenClaw 改写部署托管的配置。
另：6 月 LTS 线同周收尾，v2026.6.35（09-10）为 June Extended Stable 最终版。
Pi 0.85.x：两天两版，GPT-6 Astra 到场
- v0.85.0（09-04）：持久化 Claude 思考档位；全屏转录控制；可恢复的内存会话（
SessionManager.inMemory()，SDK 恢复外部管理的会话）； - v0.85.1（09-05）：GPT-6 Astra 进模型选择器（OpenAI API key 与 OpenAI Codex 订阅可用）；全屏模式按住 Alt 鼠标滚轮五倍速；修复 0.85.0 误发布实验代码导致的 SDK 导入失败。
Pi 连续两周的新模型接入（上周 DeepSeek V4 Flash Vision，本周 GPT-6 Astra）持续验证内核路线的模型敏捷优势，详见深度解析与产品页。
同期：DeepSeek Harness 0.1.5-rc.1
DSH 在 0.1.3-alpha 线（09-04/07）后连跳 0.1.5-alpha（09-08/09），并于 09-10 发布 0.1.5 系列首个候选版本：新增 DeepSeek-V41-Flash（deepseek-flash）适配（新会话默认，支持保留 KV Cache 的系统提示词动态更新）；Web 支持任意类型文件上传与右侧 Sidebar 多标签预览（Markdown/代码/HTML/PDF/图片）；子代理支持消息排队与 Steer；rc.2 同日跟进反馈与文件卡片体验修复。据官方 release notes，0.1.5-rc.1 同时将会话数据格式升级至 V3：受支持的旧日志迁移时保留原文件，升级后的会话不支持降级读取。自托管三强本周全部有动作，选型对照见对比总览。
