5.10 Changes
Vensim is now available for the Macintosh under OSX. Models are completely transferable between platforms and your Vensim license allows you to choose between either the Windows or the Mac versions each time you download. Some functionality, notably the display of embedded metafiles in models, is not available on the Macintosh.
We have also changed the system we are using to build Vensim on Windows. Most of this is transparent but you may see some slight numerical differences when working with the optimizer. The help files and readme notes have also changed somewhat in appearance.
The Exact hide option is now available for model variables and arrows. This can be useful for emphasizing different links by creating more than one arrow connection between two variables.
Dots only custom graphs will now vary the size of dots according to the line width setting, or use fat lines (Tools>Options>Graphics) if no line width is set. If a dot shape and size has been set (via the .vgd file directly) that setting will be used.
DSS Only: The VDF2DATA and VDF2LIST commands now allow the specification of a time range. Note that if you were using a Codepage identifier with either of these commands that will cause problems given the new argument list.
Random functions that have a min/max specification the prevents them from returning a value with the chosen distribution will now return NA instead of a uniform deviate on the specified range. Normally this only happens when the min/max specified are inconsistent with other parts of the random number specification.
Movement of tool windows and scrolling by dragging the scrollbar for all windows is smoother. SyntheSim changes should also be noticeably smoother for models that contain very granular (for example 0/1 switch) constant scales.
Bug Fixes
DSS Only batch commands could fail when running with larger models.
When the toggle for Show Behavior was on creating a new run with a different name could cause Vensim to close.
Models with Input Output objects could cause Vensim to close during simulations and games.
Numbers put out in the normal format were not consistently rounding on the final digit.
Custom graphs with line widths would have the widths apply to the wrong lines when some variable and run combinations were not available.
Stack graphs embedded in sketches could cause problems in SyntheSim.
Pro only: In the Equation Editor the "All" and "Simple" function types were transposed.
Importing Excel data with more than 32768 rows was not working.
The Model>Partial Simulation menu item would always say the model had errors and not complete.
Changing the run name and then changing a constant by clicking on the slider rails in SyntheSim could cause Vensim to close.
On some computers executing optimization with Payoff Sensitivity set could cause Vensim to close.
DSS Only: The LISTVAR control would use the first value when it was not changed by the user.
In SyntheSim if a variable was overridden to be a constant after changing views and returning to the view where the variable was overridden the slider would not be available.
If the "More" tab on the Equation editor was selected in a model with no subscripts when the Equation editor was reopened the displayed tab was incorrect and instability could result.
Numbers displayed in the Pretty format were not being consistently rounded. This may result in some differences in reported values in tables.
