[Release] openclaw/openclaw v2026.4.8: openclaw 2026.4.8

OpenClaw v2026.4.8 is a maintenance release focusing on fixing import path issues in bundled channels and plugins, improving agent execution reporting, and enhancing proxy support. Key fixes address missing file references during gateway startup, plugin compatibility metadata alignment, and Slack integration improvements. The release ensures proper fallback policies for agent execution and enables proxy-only deployments to function correctly.

Key Points

• •Fixed Telegram and bundled channels (BlueBubbles, Feishu, Google Chat, IRC, Matrix, Mattermost, Teams, Nextcloud Talk, Slack, Zalo) to load setup and secret contracts through packaged top-level sidecars, eliminating missing `dist/extensions/*/src/*` file import errors during gateway startup
• •Aligned bundled plugin compatibility metadata with v2026.4.8 release version to ensure proper loading of channels and providers
• •Maintained `update_plan` availability for OpenAI-family agent runs with compact success payloads and optional opt-out via `tools.experimental.planTool=false`
• •Fixed agent execution (`/exec`) reporting to reflect real runtime behavior with correct host-aware fallback policies: `full/off` on gateway/node, `deny/off` on sandbox (instead of stale stricter defaults)
• •Enabled Slack Socket Mode WebSocket connections to honor ambient HTTP(S) proxy settings including NO_PROXY exclusions, supporting proxy-only deployments without monkey patches
• •Fixed Slack file downloads to use already-resolved read tokens, preventing SecretRef-backed bot token failures after raw config re-reads
• •Disabled target DNS pinning in network fetch guard when trusted env-proxy mode is active, allowing proxy-only sandboxes to use trusted proxy for host resolution
