Unclear It is not clear which setting or schema the provider list belongs to, so what removing mantle means for anyone who used it is unknown.
What
Two small changes affect what Claude Code describes to programs built on it:
mantle was removed from a list of providers. The list still has bedrock, vertex, foundry and gateway.
The results of AskUserQuestion, the tool Claude uses to put a question to you, no longer include a per-question annotations field. Only the preview and notes fields remain.
The instructions that come with AskUserQuestion also changed in this release. They now tell Claude that while the question dialog is open, you may see only that dialog and not the tool results or text from earlier in the turn.
Why
Programs built on Claude Code that read these results or this provider list may notice the difference.
