Changelog

All notable user-visible changes to this project are documented here.

[Unreleased]

Changed

Fixed

Added

[3.0.3] - 2026-02-20

Changed

  • Hardened PyPI publishing CI with OIDC preflight checks and manual workflow_dispatch target selection (testpypi/pypi); installation docs now lead with python -m pip install cea and mention GitHub Releases binary assets.

Fixed

Added

[3.0.2] – 2026-02-20

Added

  • Initial Microsoft Visual C++ (MSVC) support in the C bindings/build pipeline (#29).

Changed

  • RocketSolver_solve now treats pi_p as optional for better API compatibility and easier caller usage (#36).

Fixed

  • Corrected detonation-wave upstream enthalpy calculations and upstream molecular weight handling in the legacy interface (#33).
  • Resolved failing transport-property test cases to restore expected regression behavior (#37).

[3.0.1] – 2026-02-11

Added

  • Python bindings and examples/tests for the CEA interface (Feat/icx python binding, #23).
  • rp1311_examples.inp and updated C sample output including M (1/n) (#24).
  • Windows 11 Intel oneAPI walkthrough documentation.
  • GitHub issue and pull request templates for contribution workflow.
  • A local findloc implementation in extern/fbasics for legacy compiler support.

Changed

  • Core equilibrium/rocket/shock solver iteration logic and convergence rules were refined, including area-ratio loops, throat updates, and frozen-flow gating/criteria.
  • Condensed-species handling was tightened across initialization and iteration paths (ordering, active-element indexing, phase checks, and first-iteration thermo evaluation).
  • Build and CI configuration was expanded and hardened (compiler flags/presets, broader build/test coverage, and workflow updates).
  • Precompiled thermo/transport database blobs were removed from the repository/package test assets in favor of build-time generation.
  • Documentation, contribution guidance, and sample scripts were updated for current workflows.

Fixed

  • Singular-matrix recovery paths in equilibrium condensed-species solves (including element-row singularities and related index handling).
  • Multiple convergence and initialization edge cases in shock/frozen/throat calculations (including denominator guards and corrected initial values).
  • Several compiler-compatibility issues (including Intel ifx workarounds and initialization safety fixes in mixture/transport paths).
  • Intermittent CTest instability from an extraneous C format specifier.
  • Sample/README correctness issues (including reversed example arguments and text typos).

[3.0.0] – 2025-12-31

  • Initial public release.
