What
A PostToolUse hook that sets only the older updatedMCPToolOutput field, without the newer updatedToolOutput, no longer has its rewrite applied quietly; the result is marked as suppressed instead.
Details
Separately, MCP resource text is now run through a sanitizer before being handed to the model under "Full contents of resource:".
