Download Flux now and share the happiness a well crafted utility library can bring. There are several versions available for your enjoyment:

0.4.1 - Released February 9th 2000 - ftp://ftp.styx.net/projects/flux/flux-0.4.1.tar.gz
This is the newest stable version. It has several new subsystems and close integration with the ones that already exist. Highlights are cryptography, memory management, SMTP and other typical service protocols, search trees and examples of use.

0.3.0 - Released December 17th 1999 - ftp://ftp.styx.net/projects/flux/flux-0.3.0.tar.gz
This has large improvements from the last version, 0.2.8, especially with regard to data encapsulation, as well as several new subsystems.

0.2.8 - Released August 24th 1999 - ftp://ftp.styx.net/projects/flux/libflux-0.2.8.tar.gz
This version should not be used for any new projects, as the API is severely out of date. However, if you're doing things with the Conglomerate test releases (which you shouldn't, really, they're tests, not code to be used for things) you might need it.

Nightly snapshots - ftp://ftp.styx.net/projects/flux/snapshots/
These are snapshots of the CVS tree, built at 4 AM Mexico City time every night. If you're looking for cutting edge functionality and are not afraid to use the very newest and most untested of code, this is probably for you.
