What changed
- Added x-claude-code-prompt-id to the gateway hint headers so LLM gateways can group the requests that serve one user prompt; opt in with CLAUDECODEGATEWAYHINTHEADERS=1
- Added availableModelsMatch managed setting: with "exact", an availableModels entry allows only the model version it names, so new releases stay blocked until listed
- Added deniedModels managed setting to block specific models, even when availableModels allows them
- Added MCP tool, WebFetch and WebSearch outputs to the tool.output OpenTelemetry span event when OTELLOGTOOLCONTENT=1
- Added /doctor prompt-audit (also /checkup prompt-audit) to audit your CLAUDE.md files, skills, agents and commands for prompting patterns written for older models
- Added click-to-expand for truncated messages from your other sessions in fullscreen mode
- Added path to --plugin-dir load-failure entries in the stream-json system/init pluginerrors, naming the directory that did not load
- Added an opt-in loadtestmode block to the Claude apps gateway config: requests are built and signed but not sent upstream, and clients get a canned reply, so a deployment can be load tested
