v2026.4.27

## 2026.4.27 ### Changes - Sandbox/Docker: add opt-in `sandbox.docker.gpus` passthrough for Docker sandbox containers so local GPU workloads can run inside sandboxed agents when the host Docker runtime supports `--gpus`. Fixes #57976; carries forward #58124. Thanks @cyan-ember. - iOS/Gateway: add an authenticated `node.presence.alive` protocol event and `node.list` last-seen fields so background iOS wakes can mark paired nodes recently alive without treating them as connected. Carries forward #63123. Thanks @ngutman. - Android: publish authenticated `node.presence.alive` events after node connect and background transitions so paired Android nodes retain durable last-seen metadata after disconnects. Carries forward #63123. Thanks @ngutman. - Gateway/chat: accept non-image attachments through `chat.send` by staging them as agent-readable media paths, while keeping unsupported RPC attachment paths explicit instead of silently dropping files. Fixes #48123. (#67572) Thanks @samzong. - Security/networking: add opt-in operator-managed outbound proxy routing (proxy.enabled + proxy.proxyUrl/OPENCLAW_PROXY_URL) with strict http:// forward-proxy validation, loopback-only Gateway bypass, and cleanup of proxy env/dispatcher state on exit. (#70044) Thanks @jesse-merhi and @joshavant. - Dependencies: refresh provider and tooling dependencies, including AWS SDK, PI runtime packages, AJV, Feishu SDK, Anthropic SDK, tokenjuice, and native TypeScript/oxlint tooling. Thanks @dependabot. - Matrix/QA: add live Matrix approval scenarios for exec metadata, chunked fallback, plugin approvals, deny reactions, thread targeting, and `target: "both"` delivery, with redacted artifacts preserving safe approval summaries. Thanks @gumadeiras. - Codex: add Computer Use setup for Codex-mode agents, including `/codex computer-use status/install`, marketplace discovery, optional auto-install, and fail-closed MCP server checks before Codex-mode turns start. Fixes #72094. (#71842) Thanks @pash-openai.
