[Release] openclaw/openclaw v2026.4.20-beta.1: openclaw 2026.4.20-beta.1

OpenClaw v2026.4.20-beta.1 introduces significant improvements to the onboarding wizard UI, strengthens default agent prompts, adds tiered model pricing support, and enhances session maintenance with automatic pruning. The release includes numerous fixes for provider integrations (OpenAI, Anthropic, Moonshot), plugin lifecycle management, and security hardening across multiple components including SSRF guards and environment variable isolation.

Key Points

• •Redesigned onboarding wizard with improved security disclaimer layout, loading spinners, and better visual hierarchy for key guidance
• •Enhanced default system prompts with clearer completion bias, live-state checks, and weak-result recovery mechanisms
• •Implemented tiered model pricing from cached catalogs with Moonshot Kimi K2.6/K2.5 cost estimates for accurate token-usage reporting
• •Enforced automatic session entry cap and age-based pruning at load time to prevent OOM issues in gateway before write path execution
• •Split cron runtime execution state into separate `jobs-state.json` file to keep `jobs.json` stable for git-tracked job definitions
• •Added per-group `systemPrompt` config forwarding for BlueBubbles with wildcard fallback matching for group-specific behavioral instructions
• •Implemented detached runtime registration contract for plugin executors to manage task lifecycle and cancellation independently
• •Optimized terminal logging sanitization with single regex pass instead of iterative control-character stripping
• •Fixed provider API transport normalization for OpenAI Codex, Anthropic, and custom proxies to prevent incorrect rewrites
• •Enhanced security with SSRF guards for direct-upload paths, NODE_OPTIONS env key blocking for stdio servers, and improved error handling for browser connectivity
