@@ -115,6 +115,7 @@ Docs: https://docs.openclaw.ai
 - Google/Antigravity: resolve forward-compatible Gemini 3.1 Pro custom-tools and Flash variants from the bundled Google plugin templates, so `google-antigravity/gemini-3.1-pro-preview-customtools` no longer falls through to an unknown-model error. Fixes #35512.
 - Active Memory: raise the blocking recall timeout ceiling to 120 seconds and reject larger config values during plugin schema validation. Fixes #68410. (#68480) Thanks @Bartok9.
 - Control UI/chat: keep history-backed user image uploads visible after chat reload while filtering blocked or non-image transcript media paths. (#68415) Thanks @mraleko.
+- Matrix/plugins: keep remaining Matrix event helpers on the canonical `matrix-js-sdk` subpath so build and plugin-load entrypoint checks stay consistent. (#68498) Thanks @masatohoshino.
