[Diff since v0.5.5](https://github.com/LCSB-BioCore/SBML.jl/compare/v0.5.5...v0.5.6) **Closed issues:** - Reversible Reaction handling through direct lowering to ODESystem (#51) - Throw warning instead of error when not hOSU and compartment unsized (#101) - piecewise handling fails (#112) - Stoichiometry extraction fails when species appears on both sides of chemical reaction equation (#115) **Merged pull requests:** - Turn some anonymous functions into proper named functions (#110) (@giordano) - add issue templates to promote decent format of bug reports (#113) (@exaexa) - fix argument order and count for piecewise function (#114) (@exaexa) - quickfix: do not break stoichiometry if 2 species references are present (#116) (@exaexa) - handle SBML error severities (and don't throw on warnings) (#117) (@exaexa) - Allow rescue in very deep failure with hOSU and extensive math (#118) (@exaexa)
