New features are plentiful, and add both functionality and improved MS Office compatibility. Discussion of this upgrade to the excellent and well known freeware office software suite has been plentiful during the period of Beta release, so there's no need to replicate it here.
Just go download the thing. It's available for all major platforms, after all!
A commercial version in the form of an updated version of the inexpensive Star Office is also available for those who prefer it, and it comes complete with the usual clip art, fonts, commercial spell checker and thesaurus, and support bundle.
