Added #

• Implicit Multiplication: Added support for standard algebraic shorthand (e.g., 2x, 3(a+b), (x+1)(x-1))
• Enhanced Greek Letter Support: Improved parsing of LaTeX Greek commands (e.g., \alpha, \Phi_0, \Delta E)
• Automatic Physics Constants: Solver now automatically identifies and substitutes physics constants mentioned by their symbols or keys
• Subscript Support: Improved handling of variable subscripts in both plain text (x_1) and LaTeX (x_{1})

Changed #

• Improved numerical solver's accuracy for high-sensitivity physics equations (like Rydberg formula)
• Unified math symbol rendering (π, ∞, etc.) to use standard LaTeX commands consistently
• Refined variable extraction to correctly exclude math and physics constants from "unknowns"

Fixed #

• Fixed ParentDataWidget layout conflict in solution step displays
• Resolved NaN results in complex arithmetic involving the imaginary unit i
• Improved convergence of Newton's method with expanded search ranges and better starting points

Added #

• ExpressionParser - New clean API for parsing expressions and extracting variables
• Evaluator - New class for expression evaluation with variable substitution
• Solver - New equation solver with algebraic and numerical methods
• Cas - Computer Algebra System for differentiation and integration
• ExpressionGrammar - PetitParser grammar for explicit algebraic notation
• Comprehensive documentation and examples

Changed #

• BREAKING: Complete API reorganization with cleaner, more intuitive classes
• Moved to explicit operator notation (e.g., 2*x instead of 2x)
• Improved error handling with descriptive error messages

Deprecated #

• MathEquationParser - Use ExpressionParser + Evaluator instead
• AlgebraicEquationParser - Use Solver instead
• CasParser - Use Cas instead

Fixed #

• Single-letter variables no longer incorrectly match physics constants
• Better handling of mathematical constants (pi, e, infinity)
