[Release] openclaw/openclaw v2026.3.1: openclaw 2026.3.1

OpenClaw v2026.3.1 release introduces major enhancements across multiple platforms including adaptive thinking defaults for Claude 4.6, Kubernetes health check endpoints, expanded Android device capabilities (camera, notifications, sensors), Discord/Telegram session management improvements, and WebSocket-first OpenAI streaming. The release also adds localization support (German, zh-CN), Feishu document/chat tooling, LanceDB memory customization, and numerous reliability fixes for Android, Windows, LINE, and Slack integrations.

Key Points

• •Set Claude 4.6 models to use 'adaptive' thinking level by default while keeping other reasoning-capable models at 'low' unless explicitly configured
• •Add built-in HTTP health check endpoints (/health, /healthz, /ready, /readyz) for Docker/Kubernetes container probes with fallback routing to avoid shadowing existing handlers
• •Expand Android node capabilities with camera, device permissions, health monitoring, and notification actions (open/dismiss/reply) plus first-class node-tool actions
• •Replace Discord thread fixed TTL with inactivity-based lifecycle (idleHours default 24h) and optional hard maxAgeHours limit with /session commands for control
• •Add per-DM topic configuration for Telegram with allowlists, policies, and topic-aware authorization/debounce for messages, callbacks, commands, and reactions
• •Make OpenAI Responses WebSocket-first by default with SSE fallback and preserve server-side payload mutations (store + context_management) on WS path
• •Implement lightweight bootstrap mode for automation runs (--light-context for cron and agents.*.heartbeat.lightContext) to reduce context overhead
• •Replace ad-hoc subagent completion handoffs with typed internal completion events (task_completion) for consistent rendering across direct and queued announce paths
• •Add new optional 'diffs' plugin tool for read-only diff rendering from before/after text or unified patches with gateway viewer URLs
• •Support custom OpenAI baseUrl and embedding dimensions for LanceDB memory integration
