This Beta2 version builds on feedback received since Beta1 debuted at SAS-2018 in October and has almost all the functionality of versions 4.2.x - SasView-4.2.1 is a point release for version 4.2.0 addressing issues with the built-in model editor and the NXcanSAS file reader, in particular, but which also adds a few other improvements. Additional details can be found in the respective Release Notes. Users with 64-bit machines are encouraged to use these versions.
