This release features new 64 bit packages for Linux, Mac OS X, and Windows.

New features since the previous stable release:

  • Graphical User Interface (CopasiUI)
    • Enhanced parsing of mathematical expression to allow the comparison operator <, <=, >, >=, and == as well as the Boolean operators || and &&.
    • Allowed calculation results to be selected as constraints for optimization and parameter estimation.
    • Improved display of mass conservation results. The moieties are now displayed in amount if the user is in the concentration framework.
    • Added Update Model button to the optimization result widget
    • Notes in text or XHTML format are now available for compartments, species, reactions, global quantities, events, and kinetic functions.
    • Support links in XHTML notes.
    • Support of render informations in graphical model layouts.
  • Simulation Engine
    • The calculation of statistics is no optional for optimization and parameter estimation tasks.
    • Start values can no be randomized automatically for optimization and parameter estimation tasks.
    • Enhanced MCA algorithm performance by applying a new selection criterion before each internal step.
    • Added an stochastic algorithm (Adaptive SSA/Tau-Leap) which dynamically partitions the model into parts simulated by the direct algorithm and the Tau-Leap algorithm.
  • SBML
    • Added support for constant conversion factors in Level 3.
    • Import SBML Level 3 Version 1.
    • Added SBML notes support for compartments, species, reactions, global quantities, events, and kinetic functions.
    • Added MIRIAM annotation support for events.
    • Support for the SBML Render Extension.
