## What's changed
- Added `x-claude-code-request-class`, `x-claude-code-agent-type`, `x-claude-code-prev-tool-durations`, `x-claude-code-compaction` and `x-claude-code-context-compacted` request headers for LLM gateways; opt in with `CLAUDE_CODE_GATEWAY_HINT_HEADERS=1`
- Added a notification when an MCP server disconnects mid-session and automatic reconnection gives up, pointing at `/mcp`
- Added forking a session started with `claude --remote-control` or `/remote-control` from the Claude app; the fork runs as a background session on your computer
- Fixed Bash commands the permission checker cannot fully analyze skipping the prompt under `permissions.blockReadsOutsideWorkingDirectories`, and a subshell hiding a dangerous `rm` in bypass mode
- Fixed skills synced from claude.ai staying available after your organization turns Skills off; they now move to the recoverable trash
- Fixed `allowManagedMcpServersOnly`, `deniedMcpServers` and `disableClaudeAiConnectors` set via MDM or `managed-settings.json` being ignored when server-managed settings are also present
- Fixed 401/403 errors on Bedrock, Vertex and Foundry, and Claude apps gateway 403s, telling you to run `/login`; the message now names the credential to refresh or points to your gateway administrator
- Fixed `/login`, `/upgrade`, and `/extra-usage` discarding earlier thinking from the conversation, which forced a full prompt-cache rewrite on the next request
- Fixed auto mode stopping for approval when the Artifact tool uploads a file you attached to the chat in a cloud or Remote Control sess
