+### Syntax Highlighting
+
+Comprehensive syntax highlighting for AutoIt code, including:
+
+- Keywords, functions, and macros
+- Variables, constants, and strings
+- Comments and documentation blocks
+- **COM object properties and methods** with distinct highlighting for dot notation (e.g., `$oExcel.Workbooks.Add()`)
+
+COM objects are highlighted with a special token scope (`support.class.com.autoit`), allowing themes to style them distinctly from regular functions.

 ### Added
 
+- COM object syntax highlighting for properties and methods using dot notation
+- Distinct token scopes for COM identifiers (`support.class.com.autoit`) to enable theme-specific styling
 - File path validation to prevent path traversal attacks
 - Parameter safety warnings for `autoit.consoleParams` to detect potentially dangerous shell metacharacters
 - Workspace symbol performance optimizations with batch processing to prevent UI freezing on large projects

 ### Fixed
 
+- Function pattern incorrectly matching COM object methods (e.g., `$obj.Method()` now correctly identified as COM, not function)
 - Command injection risk in registry update functionality by replacing `exec` with `execFile` for safer argument handling
 - Multiple global output panels opening for AutoIt on startup
 - Memory leak in completion provider where include cache grew indefinitely across document switches
