Claude Code is an agentic coding tool that lives in your terminal, understands your codebase, and helps you code faster by executing routine tasks, explaining complex code, and handling git workflows - all through natural language commands.

Claude Code v2.1.27 adds --from-pr flag for PR-linked session resumption and automatic PR linking via gh pr create.

$ git clone --branch v2.1.27 https://github.com/anthropics/claude-code.git
# already have the repo? check out this version:
$ git checkout v2.1.27

$ claude --from-pr 42

$ claude --from-pr https://github.com/myorg/myrepo/pull/42

• ›New --from-pr flag lets you resume a session linked to a specific GitHub PR number or URL.
• ›Sessions created via gh pr create are now automatically linked to the corresponding PR.
• ›Tool call failures and denials are now recorded in debug logs for easier troubleshooting workflows.
• ›VSCode: Enables the Claude in Chrome integration.
• ›Permissions now respect content-level ask over tool-level allow, so granular deny patterns like ask: ["Bash(rm *)"] correctly override a broad allow: ["Bash"].
