Claude Code 发布: v2.1.283

来源摘要

## What's 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 `CLAUDE_CODE_GATEWAY_HINT_HEADERS=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 `OTEL_LOG_TOOL_CONTENT=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` `plugin_errors`, naming the directory that did not load - Added an opt-in `load_test_mode` 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 - Added a `mantle` upstream provider to the Claude apps gateway for Amazon Bedrock's Mantle endpoint - Fixed SDK sessions losing a deferred tool call or finished tool result when a turn ended early, a held approval prompt after a worker restart, and a non-streaming fallback's `result.usage` - Fixed MCP progress notifications being discarded once a long-running tool call moved to the background; the background task now shows the latest progress - Fixed stdio MCP servers being left running when the session ended while they were still starting - Fixed a brief HTTP 404 from a stateless remote MCP s
