Zip 3.1 is the latest Zip update of Zip 3.x with large file and split
archive support. For now Zip 2.3x (Zip 2.32 being the current 2.x
release) remains available and supported, but users should switch to Zip
3.x as soon as possible as the Zip 2.3x code thread is getting out of
touch with modern systems.
