@@ -13,6 +13,7 @@ Docs: https://docs.openclaw.ai
 - Matrix/E2EE: keep startup bootstrap conservative for passwordless token-auth bots, still attempt the guarded repair pass without requiring `channels.matrix.password`, and document the remaining password-UIA limitation. (#66228) Thanks @SARAMALI15792.
 - Cron/announce delivery: suppress mixed-content isolated cron announce replies that end with `NO_REPLY` so trailing silent sentinels no longer leak summary text to the target channel. (#65004) thanks @neo1027144-creator.
 - Plugins/bundled channels: partition bundled channel lazy caches by active bundled root so `OPENCLAW_BUNDLED_PLUGINS_DIR` flips stop reusing stale plugin, setup, secrets, and runtime state. (#67200) Thanks @gumadeiras.
+- Packaging/plugins: prune common test/spec cargo from bundled plugin runtime dependencies and fail npm release validation if packaged test cargo reappears, keeping published tarballs leaner without plugin-specific special cases. (#67275) thanks @gumadeiras.
