Version 1.4 Released. Version 1.4 provides:

• Plug-in Custom Object Editors. Provide your customers with an interface tailored to their problem domain. You can now add your own customized object editors that replace the default inspector window. Your custom editor will be displayed whenever a user double-clicks the model's icon. Qt's Designer makes creating custom editor dialogs a snap and since your editor becomes part of your model plug-in library, no changes to OmeChron code are required.
  
• Support for MS Visual C++® 7.0 (.NET). Take advantage of the latest improvements to Visual Studio and improved C++ Language support. Improvements to the C++ Standard Library that ships with C++ 7.0 allow you build and use OmeChron without having to install STLPort. Visual Studio .NET is XML-aware and will syntax-highlight XML files including OmeChron's SML system files.

Version 1.3 Released. Version 1.3 provides: IRIX 6.5 (MipsPro 7.3.x) Support. You can now create simulations using OmeChron on current SGI® IRIX systems.

• MPI Support. Build and execute your models within the MPI environment (MPICH). Execute simulation runs in parallel across a linux cluster using MPI. The MPI capabilities are documented in the updated OmeChron Software Developers Guide. Look in your installation for these new directories :
• ./mpi_exec -- executes MPI-based models
• ./mpi_exprun -- executes experiments in parallel
• ./mpi_test_models -- an example MPI-based model plugin
• New Attribute Logging Feature. The new class SimAttrLogger is now always available to log any attribute to an XML-formatted file. New XML style sheets are provided to display the data or convert it to comma-separated values.

• An integrated experiment planner. Edit, create, and execute experiments all within the OmeChron User Interface. Manage experiment factors and automatically generate full factorial experiments.
• Native XML file format support. The new XML format is cross-platform compatible so you can easily port your simulation configurations. An XSLT stylesheet is provided so you can view your system files in a browser or convert them to spreadsheets.
• Improvements to the GUI. Inspect an object by double-clicking it's icon. View arrays of attributes in index order (sorted). Save and load different file types.
• Numerical Library. Invert matrices, fit data using linear least squares, and integrate differential equations with the new numerics library.
