[Release] openclaw/openclaw v2026.5.26: OpenClaw 2026.5.26

OpenClaw v2026.5.26 is a major release focused on performance, reliability, and security. Key improvements include faster Gateway startup through caching, transcript-backed meeting summaries as a core feature, production-ready channels (Telegram, iMessage, WhatsApp, Discord, Signal), enhanced voice/Talk capabilities with real-time inspection, and stronger content boundaries with SSRF policy enforcement. The release also hardens installation/update paths, improves observability with Activity tabs and OpenTelemetry spans, and stabilizes provider integrations.

Key Points

• •Gateway performance optimized by caching plugin metadata, channel resolution, session/auth facts, and model cost indexes to reduce startup scans and reply latency
• •Transcripts are now core infrastructure supporting meeting summaries, source-provider chunks, cleaned user turns, media provenance, and CLI/TUI replay via unified transcript path
• •Multiple channels production-ready: Telegram (typing/forum topics), iMessage (attachments/remote media), WhatsApp (group/media behavior), Discord (voice playback/model picking), Signal/iMessage/WhatsApp (reaction approvals)
• •Real-time Talk runs can be inspected, steered, cancelled, and followed up from Web UI and Discord voice; wake-name handling improved to prevent ambient speech triggering
• •Security hardened: Browser snapshots honor SSRF policy, system-event text cannot spoof prompt markers, fetched files wrapped as external content, ClickClack allowlists run before dispatch, stale device tokens rejected
• •Provider stability improved with named auth profiles, OpenAI sampling params forwarding, Codex app-server recovery, dynamic tool-schema guards, and Ollama top-p normalization
• •Installation/update reliability enhanced: Alpine installs, trusted runtime fallback roots, stable update channels, Docker/package timeouts, Windows Scheduled Tasks, and macOS runner bootstraps hardened
• •Observability expanded: Activity tab for live tool summaries, gateway secret-prep traces, tool/model stream progress, explicit fast-mode status, OpenTelemetry LLM spans, and richer telemetry signals
• •Voice improvements: shared realtime turn-context tracking, Discord speaker attribution, barge-in detection, consult question matching, and activation-name matching across platforms
• •Build and deployment: UI rebuild integrated into full/ciArtifacts profiles, Sharp replaced with Rastermill for image processing, Codex CLI updated to 0.134.0, cron.maxConcurrentRuns defaults to 8
