<h2>What's changed</h2> <ul> <li>Added <code>x-claude-code-prompt-id</code> to the gateway hint headers so LLM gateways can group the requests that serve one user prompt; opt in with <code>CLAUDE_CODE_GATEWAY_HINT_HEADERS=1</code></li> <li>Added <code>availableModelsMatch</code> managed setting: with <code>"exact"</code>, an <code>availableModels</code> entry allows only the model version it names, so new releases stay blocked until listed</li> <li>Added <code>deniedModels</code> managed setting to block specific models, even when <code>availableModels</code> allows them</li> <li>Added MCP too
