logic gates with more than two inputs were removed during conversion
logic gates connected to a phenotype were removed during conversion and lost colour and line width after export to SBGN-ML
NOT logic gates were removed when importing SBGN-ML files and reactions with NOT logic gates were missing after export to SBGN-ML
NOT logic gate with a single input is exported to CellDesigner with the same species used as both inputs
DEGRADED input of NOT logic gate in CellDesigner files is removed on import, and NOT logic gates that violate SBGN specification are removed with a warning
nested logic gates (logic gate used as an input of another logic gate) could not be imported from SBGN-ML and were lost after export to SBGN-ML
nested logic gates are removed with a warning when exporting to CellDesigner, SBML and GPML, which do not support them; export to CellDesigner failed before
logic gates had distorted arcs after export to SBGN-ML
input of a logic gate in a CellDesigner file was additionally connected directly to the reaction it modifies
glyphs with an unrecognised class broke the whole SBGN-ML file instead of being skipped
clearer warnings about logic gates with too few inputs and about logic gates that cannot be exported to SBGN-ML
