13.0.5 released May 10, 2021

  • Fixed multithreading bug that was causing combined optimal builds to run extremely slow.

  • Turning on/off the legend now works correctly on the Pareto plot.

13.0.4 released April 14, 2021

  • The dex_activate.exe utility will now copy over custom ports from the previous license to the new one.

  • Fixed display error in the factor tool where the input box appeared in the corner.

  • Changing the name of a response will now change the corresponding analysis name, if the analysis name has not already been modified.

  • Fixed a bug that caused some valid rows to be ignored when leaving the Design Layout.

  • Fixed an indexing error that would cause p-values to be out of order in the Coefficients Table.

  • New runs added via the Modify Design Space augment will now go into a new block.

  • Added missing labels back to interaction plot when the legend is off.

  • Flags can now be expanded when showing all responses in the Numerical Optimization graphs.

  • Labels on the Pareto chart now have backgrounds, and can be clicked to bring to the forefront if they are overlapping.

13.0.2 released January 25, 2021

  • Support for Big Sur.

  • Improved visibility in data tables when using a dark background (e.g. macOS Dark Mode).

  • If factor levels are missing when using Import Data, the runs are now ignored.

  • When the number of blocks changes due to an augment of a design, the block column is automatically shown.

  • Treatment means no longer show INF Std. Error for a mean model, instead they are blank.

  • Fixed a crash when clicking on Graph Columns for certain designs.

  • Fixed an issue with the Y axis changing when the legend is undocked on a histogram.

  • Importing Data now does a better job of displaying floating point numbers.

13.0.0 released December 21, 2020

Poisson Regression

  • Responses with count data can be analyzed with Poisson Regression.


  • A design space augment wizard is available to expand an existing design.

  • Runs that are outside the constraints are flagged, but can still be used in the analysis.

  • Importing data is much easier using the Import Data Set option. You just have to paste in your data.

  • A ribbon has been added to the Design Layout screen for easy access to several features.

  • You can now round factor values by right-clicking the column header.
