Generated: May 4, 2026

🚀 What's New

                    NEW PLUGIN Bundled File-Transfer Plugin
                    Agent tools: file_fetch, dir_list, dir_fetch, file_write
Binary file ops on paired nodes with 16 MB per-round-trip ceiling
Default-deny per-node path policy with operator approval
Symlink traversal refused by default (opt-in followSymlinks)

                

                    PERF Gateway Startup Optimization
                    Lazy-load plugin/runtime discovery, cron, schema, shutdown, sessions
Model metadata work only when needed
Trimmed duplicate plugin auto-enable work
Startup CPU/profile controls added

                

📡 Channel & Messaging Improvements

WhatsApp Channel/Newsletter targets — explicit @newsletter outbound with channel session metadata
Discord status reactions — improved degraded transport reporting, trackToolCalls: true for progress tracking
Telegram — suppressed stale same-session replies, improved polling startup
Slack — collapsed pong-timeout reconnects, draft preview streaming in top-level DMs
Feishu — capped sequential queue blocking (5 min default), multi-account credential resolution
Matrix — persisted pending approval reaction targets across restarts
Microsoft Teams — persisted sent-message markers across Gateway restarts

🔧 Plugin Infrastructure Hardening

Official plugin install/uninstall/update hardened for externalized plugins behaving like first-class packages
Beta-channel update paths — @beta tried first on beta OpenClaw channel, fallback to latest
ClawHub 429 annotations — reset windows and unauthenticated rate-limit hints
Source-only package rejection — broken npm artifacts fail at install time, not at runtime
Compiled runtime entry verification — catches TS-only packages before release closeout
NPM install scoped — installing one @openclaw/* plugin preserves siblings

⚡ Key Improvements

Config fails closed — invalid config no longer auto-restores; openclaw doctor --fix owns repair
macOS LaunchAgent recovery — broken upgrades recovered, health checks rerun
Google Meet stateful sessions — CLI session commands survive after starting CLI exits
Memory status clarity — sqlite-vec readiness split from embedding-provider readiness
Agent/runtime reliability — streamed replies, delayed A2A sessions, prompt/tool delivery, memory recall preserved across edge cases
Cost-runaway breaker — halts after 5 consecutive idle timeouts without model progress
Heartbeat scheduling — active-hours-aware, respects non-UTC timezones

🛠️ Developer Experience

Codex plugin — exposed as selectable provider in Manual setup onboarding
openclaw logs --follow — auto-reconnects on transient gateway disconnects
/side — new alias for /btw side questions
Shell command explainer — tree-sitter-backed explainer for future approval surfaces
Control UI fix — skill detail modal DOM connection timing fixed
/think — shows provider-specific thinking levels for active session model
TTS plugin activation — Microsoft and Local CLI voice replies work immediately after persona selection

⚠️ Pain Points & Risks

Beta stability — prerelease; plugin externalization still rolling out; some channel plugins moving from bundled to npm
Config migration — invalid config now fails closed rather than auto-repairing; operators must run doctor --fix
Plugin install complexity — source-only rejection and compiled-entry verification may break custom plugin workflows
Discord transport — degraded transport reporting improved but Discord remains a complex integration surface
Breaking: tools.deny: ["write"] no longer implicitly denies apply_patch; must deny explicitly
