Claude Code 发布: v2.1.281

来源摘要

## What's changed - Added Claude apps gateway support for newer Claude Desktop keys in `desktop` policy blocks, including `blockReadsOutsideWorkingDirectories` and `disableBypassPermissionsMode` - Added `assume_role` on Claude apps gateway Bedrock upstreams: the gateway calls Bedrock as an IAM role it assumes through STS, in another AWS account if needed, optionally one session per developer - Added `guardrail: {id, version}` on Claude apps gateway Bedrock upstreams to apply an Amazon Bedrock guardrail to every request sent through them (set it on all Bedrock upstreams or none) - Added `telemetry.resource_attributes` to the Claude apps gateway config, to put fixed labels on the telemetry of Claude Desktop and `/login` sessions - Added `"attribution": false` in `settings.json` to hide all commit and PR attribution; older CLI versions skip a settings file that holds it, so keep the object form in files shared across versions - Added MCP URL-mode elicitation on 2026-07-28 protocol connections, so servers can ask Claude Code to open a browser-based flow; no waiting dialog is left on screen when the server has no way to confirm completion - Added MCP server checks to `claude plugin validate`: it reports `.mcp.json` entries that would be silently dropped at load, undeclared `${user_config.*}` references, and insecure URLs - Added an auto mode recommendation to `/insights` that estimates how many permission prompts auto mode could have handled in your recent sessions - Added a scrollbar to the `/skills`, `/mcp` and `/plugin` Installed lists in fullscreen mode, like the one `/workflows` now has: it appears while the mouse is over the list and can be clicked or dragged - Fixed a crash ("unrecoverable interface error") that could end a session while an API request was being retri
