[Release] openclaw/openclaw v2026.4.23-beta.6: openclaw 2026.4.23-beta.6

OpenClaw v2026.4.23-beta.6 introduces significant enhancements to image generation across multiple providers (OpenAI, OpenRouter), adds optional forked context for subagents, implements per-call timeout support for generation tools, and includes configurable local embedding context sizes. The release also delivers numerous fixes for Codex harness routing, media handling, provider authentication, and UI persistence, improving reliability across chat platforms including Slack, Telegram, WhatsApp, and WebChat.

Key Points

• •Enable image generation without API keys using Codex OAuth for OpenAI and OpenRouter image models
• •Add optional forked context for subagent sessions to inherit requester transcripts while maintaining isolated default sessions
• •Implement per-call `timeoutMs` support for image, video, music, and TTS generation tools for flexible provider request timeouts
• •Introduce configurable `memorySearch.local.contextSize` (default 4096) for tuning local embeddings on constrained hosts
• •Fix Codex harness routing for native `request_user_input` prompts and preserve queued follow-up answers
• •Resolve Windows npm-installed `codex.cmd` shims through PATHEXT for native app-server compatibility
• •Suppress verbose tool/plan progress on Slack non-DM surfaces to prevent internal traces from leaking into rooms
• •Preserve image attachments for text-only models by offloading as media references instead of dropping them
• •Support `codex/*` image models through bounded Codex app-server image turns with protocol validation
• •Persist assistant-generated images as authenticated managed media and accept paired-device tokens for history reload
