Release notes for cobrapy 0.9.1


  • All around improvements to cobrapy’s continuous integration.
  • Pin the scipy version to 0.19.1 until we can upgrade our sparse matrix code to scipy 1.0.

New features

  • Compatibility with symengine. Symengine can now power optlang and thus make many simulation tasks faster. Please try it out! It’s as simple as pip install symengine.
  • When writing to JSON or YAML metabolites, reactions, and genes by default maintain the order of the model. Their annotations are alphabetically sorted.
  • Duplicate reactions are now properly ignored. They were causing ValueErrors before.
  • Automatic GitHub releases upon tagged releases.
  • Automatic deployment of website upon tagged releases.
