 - ❌ DON'T: Remove deprecated features without proper notice period
 
 ### Deprecation Process
-1. Mark as deprecated with `warnings.warn()` and `@deprecated` decorator
-2. Document replacement in deprecation message
+1. Use the standardized `@deprecated` decorator from `project_x_py.utils.deprecation`
+2. Provide clear reason, version info, and replacement path
 3. Keep deprecated feature for at least 2 minor versions
 4. Remove only in major version releases (4.0.0, 5.0.0, etc.)
 
 Example:
 ```python
-import warnings
-from typing import deprecated
-
-@deprecated("Use new_method() instead. Will be removed in v4.0.0")
+from project_x_py.utils.deprecation import deprecated, deprecated_class
+
+# For functions/methods
+@deprecated(
+    reason="Method renamed for clarity",
+    version="3.1.14",  # When deprecated
+    removal_version="4.0.0",  # When it will be removed
+    replacement="new_method()"  # What to use instead
+)
 def old_method(self):
-    warnings.warn(
-        "old_method() is deprecated, use new_method() instead. "
-        "Will be removed in v4.0.0",
-        DeprecationWarning,
-        stacklevel=2
-    )
     return self.new_method()
+
+# For classes
+@deprecated_class(
+    reason="Integrated into TradingSuite",
+    version="3.1.14",
+    removal_version="4.0.0",
+    replacement="TradingSuite"
+)
+class OldManager:
+    pass
 ```
 
+The standardized deprecation utilities provide:
+- Consistent warning messages across the SDK
+- Automatic docstring updates with deprecation info
+- IDE support through the `deprecated` package
+- Metadata tracking for deprecation management
+- Support for functions, methods, classes, and parameters
+
+## Development Documentation
+
+### Important: Keep Project Clean - Use External Documentation
+
+**DO NOT create project files for**:
+- Personal development notes
+- Temporary planning documents
+- Testing logs and results
+- Work-in-progress documentation
+- Meeting notes or discussions
+
+**Instead, use**:
+- External documentation tools (Obsidian, Notion, etc.)
+- GitHub Issues for bug tracking
+- GitHub Discussions for architecture decisions
+- Pull Request descriptions for implementation details
+
+This keeps the project repository clean and focused on production code.

+
+### Added
+- **🎯 Comprehensive Type System Overhaul**: Major improvements to type safety across the SDK
+  - Added TypedDict definitions for all API responses and callback data structures
+  - Created comprehensive Protocol definitions for all major SDK components
+  - Implemented proper type hints for all async/await patterns
+  - Added type-safe event data structures for the EventBus system
+
+- **📊 StatsTrackingMixin**: New mixin for comprehensive error and memory tracking
+  - Automatic error history tracking with configurable limits
+  - Memory usage statistics for all managers
+  - Performance metrics collection
+  - Integrated into OrderManager, PositionManager, OrderBook, and RiskManager
+
+- **📋 Standardized Deprecation System**: Unified deprecation handling across SDK
+  - New `@deprecated` and `@deprecated_class` decorators
+  - Consistent version tracking and removal schedules
+  - Clear migration paths in all deprecation messages
+  - Metadata tracking for deprecated features
+
+- **🧪 Comprehensive Test Coverage**: Added 47 new tests for type system
+  - Full test coverage for new TypedDict definitions
+  - Protocol compliance testing
+  - Task management mixin testing
+  - Increased overall test coverage significantly
+
+### Fixed
+- **🔧 Type Hierarchy Issues**: Resolved all client mixin type conflicts
+  - Fixed incompatible type hierarchy between ProjectXBase and ProjectXClientProtocol
+  - Corrected mixin method signatures to work properly with base class
+  - Added proper attribute declarations in mixins
+  - Fixed all "self" type annotations in mixin methods
+
+- **✅ Response Type Handling**: Fixed union type issues in API responses
+  - Added isinstance checks before calling .get() on API responses
+  - Properly handle dict|list union types from _make_request
+  - Fixed all "Item 'list[Any]' has no attribute 'get'" errors
+  - Improved error handling for malformed API responses
+
+- **🧑 Task Management**: Fixed async task lifecycle issues
+  - Properly handle task cleanup on cancellation
+  - Fixed WeakSet usage for garbage collection
+  - Resolved all asyncio deprecation warnings
+  - Improved error propagation in background tasks
+
+### Improved
+- **📦 Code Organization**: Major structural improvements
+  - Consolidated duplicate order tracking functionality
+  - Removed dead code and unused features
+  - Cleaned up imports and removed unnecessary TYPE_CHECKING blocks
+  - Standardized error handling patterns
+
+- **📝 Type Safety**: Dramatically improved type checking
+  - Reduced type errors from 100+ to just 13 edge cases
+  - All core modules now pass strict type checking
+  - Better IDE support with proper type hints
+  - Improved code completion and static analysis
+
+- **🎯 API Consistency**: Standardized patterns across SDK
+  - Consistent use of async/await patterns
+  - Unified event handling through EventBus
+  - Standardized error messages and logging
+  - Consistent method naming conventions
+
+### Performance
+- Memory tracking now integrated into all major components
+- Better garbage collection with proper weak references
+- Optimized event emission to prevent handler deadlocks
+- Improved type checking performance with better annotations
+
+### Breaking Changes
+- None - Full backward compatibility maintained
+
+### Deprecations
+- Legacy callback methods in OrderTrackingMixin (use EventBus instead)
+- Several internal utility functions marked for removal in v4.0.0
+
+### Migration Notes
+No migration required from v3.1.x. The type system improvements are fully backward compatible.
+If you experience any type checking issues in your code:
+1. Update your type hints to match the new Protocol definitions
+2. Use the provided TypedDict types for API responses
+3. Follow the examples in the documentation for proper async patterns
