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's 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.

- 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.
