Release Notes

Version 1.2.0

Summary

This release focuses on symbolic case analysis improvements, test-suite reorganization and expansion, and documentation updates since v1.1.0.

Changelog

Features & Enhancements

• Added symbolic RREF case exploration for parameterized systems and integrated it into higher-level case evaluation flows.
• Improved deterministic grouping and ordering behavior in symbolic case evaluation output.
• Moved sympy_commands() into utils.py.
• Extended tutorial coverage and aligned test organization with chapter/tutorial structure.
• Updated docs build and release automation setup (including offline docs/release artifact workflow updates).

Bug Fixes

• Fixed matrix LaTeX rendering behavior for cases where printer context or augmentation metadata differ.
• Fixed decomposition/custom-type LaTeX and evaluation edge cases, including inverse-handling paths for PDP.
• Fixed regressions in symbolic case ordering/branching and refreshed affected tests.
• Fixed formatting and consistency issues across docs/source to satisfy linting and test expectations.

Migration Notes

• No intentional breaking API changes are expected for most users.
• Matrix.evaluate_cases(...) changed signature and behavior:
  • v1.1.0: evaluate_cases(self, rhs: Matrix | None = None, use_ref: bool = True) -> None
  • v1.2.0: evaluate_cases(self, rhs: Matrix | None = None, verbosity: int = 0) -> list[RREFCase]
  • use_ref is deprecated as evaluate_cases now use RREF for clearer analysis.
  • list[RREFCase] is now returned so that it can be used in downstream tasks.
• Matrix.rref_cases(...) is a new public API for raw symbolic case enumeration.
• Matrix.find_all_cases() was removed from Matrix as Matrix.rref_cases() is more thorough and easier to use.
• Matrix.solve(...) now accepts verbosity: int = 0 (backward-compatible default).
• sympy_commands moved out of ma1522.symbolic to ma1522.utils, and is re-exported at package level (from ma1522 import sympy_commands).
