 - Update: allow pnpm GitHub-source OpenClaw updates to approve the OpenClaw package build, so source installs complete their prepare/prepack lifecycle. (#81294) Thanks @fuller-stack-dev.
 - Test state: seed isolated auth-profile secret keys for generated homes, preventing helper-backed proof runs from falling back to host Keychain secrets. (#81393) Thanks @altaywtf.
 - Plugins/runtime: attribute deprecated runtime config load/write warnings to the plugin id and source that triggered them so logs and plugin doctor runs are actionable. Refs #81394. (#81425) Thanks @BKF-Gitty.
+- Memory/LanceDB: make auto-capture recognize short CJK memory phrases and configurable literal triggers, so Chinese, Japanese, and Korean users can capture memories without regex or LLM intent detection. Fixes #75680. Thanks @vyctorbrzezowski and @guokewuming.
