@@ -10,6 +10,7 @@ Docs: https://docs.openclaw.ai
 - Require admin scope for node device token management [AI]. (#81067) Thanks @pgondhi987.
 - Restrict chat sender allowlist matching [AI]. (#80898) Thanks @pgondhi987.
 - Sessions: redact persisted tool result detail metadata before writing transcripts so diagnostic secrets do not survive tool output redaction. (#80444) Thanks @nimbleenigma.
+- Codex runtime: allow the official installed `@openclaw/codex` package to use its private task-runtime SDK helper, fixing `MODULE_NOT_FOUND` during migrated OpenAI/Codex beta runs.
 - Codex migration: make Enter activate the highlighted checkbox row before continuing, so `Skip for now` and bulk-selection rows work even when planned items start preselected.
 - fix: harden safe-bin argument validation [AI]. (#80999) Thanks @pgondhi987.
 - fix: scan plugin runtime entries during install [AI]. (#80998) Thanks @pgondhi987.
