Release Notes - v0.17.7

🎯 Test Coverage & Quality Improvements

This release represents a significant investment in code quality and test infrastructure, adding comprehensive test coverage for critical physics modules and improving overall test coverage from 40.2% to 45.55%.

📊 Major Achievements

Test Coverage Enhancements

• 132 new physics module tests added with 100% pass rate
• Test coverage improved from 40.2% to 45.55% for production code
• Zero test failures - All 1,641 tests passing
• Coverage configuration added to exclude non-production code

New Comprehensive Test Suites

Atmosphere Module (test_atmosphere.py) - 20 tests for atmospheric calculations - CIPM air density validation - ICAO standard atmosphere compliance - Temperature, pressure, and humidity effects

BC Validation Module (test_bc_validation.py) - 30 tests for ballistic coefficient validation - Segment validation and monotonicity checks - BC range estimation - Source analysis (manufacturer vs doppler data)

Stability Calculator (test_stability_calculator.py) - 25 tests for gyroscopic stability - Miller and Greenhill formula validation - Dynamic stability assessment - Auto-enable precession/nutation logic

Transonic Drag Module (test_transonic_drag.py) - 32 tests for transonic drag modeling - Prandtl-Glauert corrections - Wave drag calculations - Critical Mach number detection

Custom Drag Module (test_custom_drag.py) - 25 tests for custom drag functions - CDF library management - BC calculation from drag curves - Drag function interpolation

🔧 Technical Improvements

Code Quality

• Fixed all API mismatches between tests and implementations
• Removed 6 obsolete tests for non-existent APIs
• Standardized function signatures across physics modules
• Improved Mock object attributes in tests
