CBMPy release 0.8.4

Current release This is primarily a bugfix/maintenance release, that adds Python 3.10 and the latest libSBML compatibility. Many thanks go to all who identified issues and suggested code improvements (see CONTRIBUTORS and RELEASES for details). About CBMPy CBMPy (http://cbmpy.sourceforge.net) is a new platform for constraint based modelling and analysis. It has been designed using principles developed in the PySCeS simulation software project: usability, flexibility and accessibility. Its architecture is both extensible and flexible using data structures that are intuitive to the biologist (metabolites, reactions, compartments) while transparently translating these into the underlying mathematical structures used in advanced analysis (LP's, MILP's). CBMPy implements popular analyses such as FBA, FVA, element/charge balancing, network analysis and model editing as well as advanced methods developed specifically for the ecosystem modelling: minimal distance methods, flux minimization and input selection.
