Claude Code changes

New Documents

CLAUDE.md [Source]

New documentation page explaining CLAUDE.md files - markdown files placed in project roots that Claude Code reads at the start of every session. Use them to set coding standards, architecture decisions, preferred libraries, and review checklists. The page currently shows as a 404 error but provides links to related documentation on skills, best practices, and memory.

Changed documents

Claude Code on the web [Source]

• Clarified availability for Enterprise users: now explicitly states "Enterprise users with premium seats or Chat + Claude Code seats" instead of just "Enterprise premium seat users". [line 25] [Source]
• Added new section explaining that custom environment images and snapshots are not yet supported, with SessionStart hooks as a workaround. [lines 250-251] [Source]
• Updated SessionStart hook example to include CLAUDE_CODE_REMOTE environment variable check, allowing hooks to execute only in remote environments. [lines 283-285] [Source]
• Added new "Dependency management limitations" section documenting four key limitations: hooks fire for all sessions, requires network access, proxy compatibility issues, and runs on every session start. [lines 301-305] [Source]

Desktop [Source]

• Added new "Act" mode to the mode selector documentation, which runs without permission checks and automatically executes file edits and terminal commands. [lines 103-106] [Source]
• Added explanation that Act mode runs in bypassPermissions mode and should only be used in isolated environments like containers or VMs. Documented that it requires admin enablement for Team/Enterprise and personal settings enablement for personal accounts. [line 106] [Source]

• Complete page restructure: Changed from simple prerequisites and installation instructions to a comprehensive overview with tabbed environment selection (Terminal, VS Code, Desktop app, Web, JetBrains). [lines 1-85] [Source]
• Replaced "What Claude Code does for you" and "Why developers love Claude Code" sections with new "What you can do" section featuring practical use cases with code examples. [lines 87-141] [Source]
• Added new content sections: "Automate the work you keep putting off", "Build features and fix bugs", "Create commits and pull requests", "Connect your tools with MCP", "Customize with instructions, skills, and hooks", "Run agent teams and build custom agents", "Pipe, script, and automate with the CLI", and "Work from anywhere". [lines 89-158] [Source]
• Restructured "Use Claude Code everywhere" section into a comparison table showing best options for different use cases. [lines 163-170] [Source]
