Change Log

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog and this project adheres to Semantic Versioning.

Changed

  • Catch FileNotFoundErrors instead of OSErrors when files are missing

  • Minimum version of Cantera is 2.3.0

Removed
