Build 4.5.0.25 of xlsgen fixes a problem related to page fields in pivot tables.

When a single item is selected in a page field, Excel defaults to a single-selection UI instead of a multi-selection UI. Oddly enough, this is stored differently in the file too, whether it's a XLS, a XLSX or a XLSB file. xlsgen now does this too even though this is a design snafu.

What this build of xlsgen also brings to the table is perhaps more interesting to the client application developer : it's the ability to select items without unselecting them all first. Indeed, by default, all items in the field are selected by default. And if you'd like to select just one or two of them, before this build, you would have to unselect them all (there is a method that does this in a single call), and only then start selecting single items. With this build, the prior unselection is done for you so you don't have to.
