CHANGELOG.md

@@ -9,11 +9,16 @@ Docs: https://docs.clawd.bot
 - Exec: add `/exec` directive for per-session exec defaults (host/security/ask/node).
 - macOS: migrate exec approvals to `~/.clawdbot/exec-approvals.json` with per-agent allowlists and skill auto-allow toggle.
 - macOS: add approvals socket UI server + node exec lifecycle events.
+- Nodes: add headless node host (`clawdbot node start`) for `system.run`/`system.which`.
+- Nodes: add node daemon service install/status/start/stop/restart.
+- Bridge: add `skills.bins` RPC to support node host auto-allow skill bins.
 - Slash commands: replace `/cost` with `/usage off|tokens|full` to control per-response usage footer; `/usage` no longer aliases `/status`. (Supersedes #1140) — thanks @Nachx639.
 - Sessions: add daily reset policy with per-type overrides and idle windows (default 4am local), preserving legacy idle-only configs. (#1146) — thanks @austinm911.
 - Docs: refresh exec/elevated/exec-approvals docs for the new flow. https://docs.clawd.bot/tools/exec-approvals
+- Docs: add node host CLI + update exec approvals/bridge protocol docs. https://docs.clawd.bot/cli/node
 
 ### Fixes
+- Exec approvals: enforce allowlist when ask is off; prefer raw command for node approvals/events.
 - Tools: return a companion-app-required message when node exec is requested with no paired node.
 - Streaming: emit assistant deltas for OpenAI-compatible SSE chunks. (#1147) — thanks @alauppe.
