[Release] openclaw/openclaw v2026.5.16-beta.3: openclaw 2026.5.16-beta.3

OpenClaw v2026.5.16-beta.3 introduces xAI Grok OAuth authentication, enhanced cron scheduling with wait controls, multilingual onboarding support, and significant performance improvements through skill caching. The release includes numerous fixes for gateway diagnostics, session management, channel integrations (Telegram, Discord, Matrix, Slack), and context handling to improve reliability and security across the platform.

Key Points

• •xAI Grok OAuth login now available for SuperGrok subscribers, eliminating need for XAI_API_KEY environment variable
• •CLI cron improvements: `--wait` flag with timeout/poll controls and `--run-id` filtering for blocking on queued manual runs
• •Skill caching optimization: `resolvedSkills` cached across warm gateway turns, reducing redundant snapshot rebuilds while respecting config boundaries
• •Multilingual onboarding: setup wizard and channel flows localized for English, Simplified Chinese, and Traditional Chinese
• •Gateway diagnostics enhanced: credential URLs redacted in logs while preserving raw connection URLs for programmatic access
• •Session isolation fix: multi-agent gateway state scoped by agent ID to prevent cross-agent session data leakage
• •Telegram consistency: group target resolution normalized via `resolveSessionTarget` hook for reliable scheduled announcements
• •Context compaction improvements: long-running turns kept alive during approvals/user input/dynamic tools, with progress carried into outer run timeout
• •WebChat image handling: image attachments routed through vision-capable model plan with fallback chain support
• •Auth security: provider login writes serialized through auth-profile lock for OpenAI Codex, Anthropic, Cloudflare, GitHub Copilot, and z.ai
