New Features

  • Simulation Engine
    • Species particle numbers are no supported as event targets.
    • Optimization & Parameter Estimation: It is now possible to run current solution statistics before adding any optimization parameters.

Bug Fixes

  • Graphical User Interface (CopasiUI)
    • Reduced COPASI‚Äôs start up time.
    • Fixed display of message boxes under Qt 6.5.
    • Improved functionality and stability of the plotting engines QWT & QCustomPlot
    • The output assistant suppresses now any check boxes which are not applicable to the current task.
    • Improved display of SBML imported units.
    • Fixed rare crash occurring when lading a new file while displaying a global quantity.
  • Simulation Engine
    • Utilize balanced Abstract Syntax Tree to avoid stack overflows.
    • Fixed loading of COPASI files containing parameter estimation created with COPASI 4.0 (Build 18).
    • The COPASI Version is now correctly displayed in reports.
    • Fixed an error message for trajectory method RK45 which was referring to LSODA.
  • Standards
    • SBML Import: Corrected function parameter classification which effected the UI parameter overview.
    • SBML Import: Avoid redundant division by log(10) when importing logarithm with base 10.
    • SBML Import (layout): Allow import of empty curves.
    • SED-ML Import: Improved import of SED-ML files with multiple task lists, falling back to SBML when all fail.
    • SED-ML Import: Create a warning message when referenced the SBML model is remote resource (unsupported).
  • API & Language Bindings
    • Added utility function CFunctionDB::purgeUnusedUserDefinedFunctions().
    • Added editing of constraints in optimization and parameter estimation tasks.
