[Release] openclaw/openclaw v2026.5.26-beta.1: openclaw 2026.5.26-beta.1

OpenClaw v2026.5.26-beta.1 delivers significant performance improvements through reply optimization and metadata caching, enhances voice and multi-channel capabilities with realtime Talk inspection and improved channel support (Telegram, iMessage, WhatsApp, Discord, Signal), strengthens agent safety with better auth and sandbox handling, and introduces new observability features including Activity tabs and OpenTelemetry LLM spans. The release also replaces Sharp with Rastermill for image processing, adds transcript capture support, and hardens installation/update reliability across Windows, macOS, and Docker platforms.

Key Points

• •Faster replies via separated user-facing sends from follow-up work and hot-path metadata reuse; Gateway startup avoids repeated plugin/channel/session scans
• •Realtime Talk runs now inspectable, steerable, and cancellable from Web UI and Discord voice with improved wake-name tolerance
• •Production-ready channels: Telegram typing context, iMessage attachments, WhatsApp group/media, Discord voice improvements, Signal/iMessage reaction approvals
• •Enhanced agent safety through Codex app-server auth, sandbox path handling, usage-limit recovery, and OpenAI-compatible provider robustness
• •New observability: Activity tab, gateway secret-prep traces, tool/model stream progress, OpenTelemetry LLM spans, and alertable telemetry signals
• •Transcript capture and source-provider support for meeting summaries with renamed Transcripts docs and CLI surface
• •Named model login profiles with credential migration for Hermes, OpenCode, and Codex auth; explicit opt-out and non-interactive controls
• •Performance optimization: cached plugin metadata, package realpaths, model cost indexes, channel resolution, and session/auth hot-path facts
• •Shared realtime voice SDK components for turn-context tracking, speaker attribution, barge-in detection, and activation-name matching across Discord, browser, and meeting surfaces
• •Image processing backend replaced Sharp with Rastermill for metadata, resizing, EXIF orientation, and PNG alpha preservation without external dependencies
