Claude Code adds forking of remote-control sessions as background jobs

Claude Code v2.1.273 adds the ability to fork a session started with claude --remote-control or /remote-control from the Claude app, running the fork as a background session on your computer.

The release notes for Claude Code v2.1.273 list several changes. The most useful new capability for everyday work is the ability to fork a session started with claude --remote-control or /remote-control from the Claude app. The fork runs as a background session on your computer. This means you can branch off a remote-controlled session and continue working locally without interrupting the original session. The release also adds opt-in request headers for LLM gateways and a notification when an MCP server disconnects and reconnection gives up.
