new development build is now available for download.
i've added optimizer and minimizer filters into this build, see menu 'package - reduce - optimize coverage'. the optimizer and minimizer filters from version 4.x are merged into a single filter window.
the new filter is heavily optimized so it needs less memory than in version 4.x. the filtering is also faster because the new implementation is multi-threaded (any running expert lotto on core i7?:)
there's also 'custom combinations' coverage filter in expert lotto 4.x but unless there's any interested in that filter i won't bother implementing it in version 5.
