Programs Version and Build numbers

Every ASPEN software program release is assigned a major number and a minor version number. The major version number is incremented between major software releases when major changes in program features, network, and relay models happen. The minor version number is incremented between maintenance software releases, which consists of fixes for software bugs and some new and enhanced program features. As a rule, no new parameters are introduced for any network or relay objects in maintenance releases. As the result, data files created in the different minor version releases of the same major version number are always fully compatible.

​

ASPEN regularly creates new program builds with fixes for software bugs and makes these updates available to users. Both major and minor version numbers are kept unchanged in these builds. Only the program build number, and the build date, are incremented.
