Compatibility with previous releases

Scripts created in previous releases of IBM® SPSS® Modeler should generally work unchanged in the current release. However, model nuggets may now be inserted in the stream automatically (this is the default setting), and may either replace or supplement an existing nugget of that type in the stream. Whether this actually happens depends on the settings of the Add model to stream and Replace previous model options (Tools > Options > User Options > Notifications). You may, for example, need to modify a script from a previous release in which nugget replacement is handled by deleting the existing nugget and inserting the new one.

Scripts created in the current release may not work in earlier releases.

If a script created in an older release uses a command that has since been replaced (or deprecated), the old form will still be supported, but a warning message will be displayed. For example, the old generated keyword has been replaced by model, and clear generated has been replaced by clear generated palette. Scripts that use the old forms will still run, but a warning will be displayed.
