Claude Code v0.2.69

# Claude Code v0.2.69 Changelog

• Added deny permissions support: The permission system now supports both allow and deny rules for tools, giving users more granular control over what tools can be used in their projects.

Usage example:

  {
    "permissions": {
      "allow": ["Read", "Write"],
      "deny": ["Bash", "WebFetch"]
    }
  }

Previously, only allow rules were supported. Now you can explicitly deny specific tools even if they might be allowed by other rules.

• New deny rules functionality: Added support for "always deny" rules alongside the existing "always allow" rules. This provides a more comprehensive permission model where certain tools can be permanently blocked.

• Rule source tracking: Permission rules now track their source (e.g., "projectSettings", "localSettings") and behavior type ("allow" or "deny"), making it easier to understand why a tool is allowed or denied.

• Stream handling update: Switched from default stream import to using named PassThrough import, improving code clarity and tree-shaking capabilities.

• Process module update: Changed from default process import to named cwd import for better modularity.

• Added $j2 function: A new string processing utility that splits text by newlines, processes each line, and rejoins them. This appears to be used for formatting multi-line content.

• Added Hb5 function: Retrieves all deny rules from the permission system, formatting them with their source and rule details.

• Added Ab5 function: Checks if a specific tool is denied by any rule, returning the matching deny rule if found.

• Fixed rule removal logic: The Pj2 function (formerly Lj2) now correctly handles both allow and deny rules when removing permissions from project settings. Previously, it only supported removing "allow" rules.

• Fixed rule addition logic: The Tj2 function now properly handles both allow and deny rules when adding new permissions, instead of throwing an error for non-allow rules.

• The permission object schema (Yb5) now includes both allow and deny arrays:

  {
    permissions: {
      allow: ["Tool1", "Tool2"],  // optional
      deny: ["Tool3", "Tool4"]     // optional
    }
  }

• Added new constant oy5 = 13 (appears to be a configuration value)
• Added new constant ii5 = 3 (appears to be a configuration value)
• Removed constant ci5 = 10

None identified. The changes maintain backward compatibility while extending functionality.

Projects using the previous permission system will continue to work as before. The new deny rules are optional and only take effect when explicitly configured. Existing "allow-only" configurations remain valid.
