Ventity 4.9.1 is now available from the download page (if you need a trial license) or the update page (if you don’t). 4.9.1 is a minor maintenance release that improves trapping and messages for generated code errors, fixes a file format issue with the 3D visualizer, and corrects a rare action issue. 4.9 is a

Release 4.8 is primarily an under-the-hood upgrade, with enhanced performance and functionality supporting use of large models in embedded systems. Contact us if this application is of interest. There are also bug fixes and minor usability improvements, including: Optimization setup improvements. Fix for issues with the undo/redo stack. Multi-slider interface improvements. Exclusion of system variables

This build contains a variety of improvements to interface and simulation engine components. New features include: · Circularity checking is now lest strict, to permit entitytypes to self-reference where hierarchies are useful, as in project or supply chain models. Potential circularities cause a user-controlled warning at compile time, and actual circularities cause a run-time error.

The Ventity 4.6 beta is primarily an under-the-hood performance enhancement, with a few bug fixes and feature improvements as well. The primary feature enhancements are to Process List actions, making it easier to restrict the number of iterations, and much faster to make small randomized selections from large entity collections. This version is stable in

Ventity 4.5 is now available for download or upgrade. There are some further performance improvements over 4.4, as well as a few critical bug fixes to the Initial() and DelayInformation() functions. A number of minor bugs have been fixed as well, including the occasional tendency of autocomplete to delete left parentheses when adding variables to

This is a full version 4 release. There are no major new features beyond the many introduced in the v4 beta. The emphasis is on speed and memory improvements in the simulation engine. Diagram tool behavior is a little more Vensim-like, with fewer clicks required to accomplish some tasks, and the toolbar now includes a

This is a preliminary version 4 release. New features and improvements: Vector export of charts Slider moves in large models interrupt and restart the current simulation, reducing lag Bar charts Save sliders as a dataset Navigation history for moving forward-back through model diagrams “Select all” for savelists Action logging Macros Components Diagram bounding box and

This is a minor maintenance release. Adds string functions for attribute initialization. Fixes license grace period. Improves consistency of computation when actions are triggered by random events at start of period. Reduces flicker in GIS visualization rendering. Provides control-drag for drawing initial arrows between stocks. Improves lat-lon defaults for GIS visualization with fixed coordinates. Improves

This is a minor maintenance release, but it brings substantial improvements to the beta GIS visualizer. See the Help System for details.
