Upgrade Notes

  • New license required! All licenses issued for version 3.0 won't work with version 3.1. A license upgrade to version 3.x is offered FREE OF CHARGE. The new license file will be sent to you automatically. Please contact Technical Support in case of problems.
  • MS Installer now installs PEAXACT "per machine" (for all users) instead of "per user" (for current user only). Due to this change, previous versions cannot be updated automatically. Please uninstall all previous versions before updating to 3.1.
  • PEAXACT 32-bit now requires installation of the Visual C++ Redistributables package. This only affects users who continously updated PEAXACT from version 2.9 without ever installing the VC++ Redistributables package so far.
  • The PEAXACT External Interface has been completely rewritten. Integration of PEAXACT with OPUS Process requires updating OPUS Scenario script files. Please contact Technical Support to get help.

Compatibility Considerations

  • Data pretreatment option "vector standardization" was calculated inccorectly. Models using this option should be revised. Contact Technical Support if you need help.
  • Integration ranges with overlapping excluded ranges were calculated incorrectly. Models using integration ranges which are overlapped by excluded ranges should be revised. Contact Technical Support if you need help.
  • Component Fitting (Hard Model Fitting) now uses individual component scaling instead of overall component scaling. This may result in slightly different component fits compared to previous versions.
  • User preference "Initialization of fits" has been changed. Options "component fit at previous time/location" (so-called warm start) has been removed and replaced by option "linear fit". This only affects Hard models using the warm start option.
  • A new session files format is used as of 3.1; loading session files saved prior to version 3.1 does not restore the selection of items in the Model Tree Panel and Data Sets Panel.
