@@ -74,6 +74,7 @@ Docs: https://docs.openclaw.ai
 - Discord/Telegram outbound runtime config: thread runtime-resolved config through Discord and Telegram send paths so SecretRef-based credentials stay resolved during message delivery. (#42352) Thanks @joshavant.
 - Secrets/SecretRef: reject exec SecretRef traversal ids across schema, runtime, and gateway. (#42370) Thanks @joshavant.
 - Telegram/docs: clarify that `channels.telegram.groups` allowlists chats while `groupAllowFrom` allowlists users inside those chats, and point invalid negative chat IDs at the right config key. (#42451) Thanks @altaywtf.
+- Models/Alibaba Cloud Model Studio: wire `MODELSTUDIO_API_KEY` through shared env auth, implicit provider discovery, and shell-env fallback so onboarding works outside the wizard too. (#40634) Thanks @pomelo-nwu.
