@@ -9,6 +9,7 @@ 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.
+- Plugins: add typed lifecycle hooks + vector memory plugin. (#1149) — thanks @radek-paclt.
 - 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
