Support for item stores. You can now use the STORE statement to save your COUNTREG model, parameter estimates, and other statistics in an item store and use the RESTORE option to restore them from your item store. You can use the new SHOW statement to view the contents of your item store and the new SCORE statement to score a data set using the estimates preserved in your item store.

Support for new options in the CLASS statement. These new options allow you to control parameterization method, reference levels, and sort order for your classification variables.
