Apimac has released a new version of its compression tool that supports the creation of XAR archives. XAR, or eXtensible ARchive format, is a new way to compress files. XAR was created within the OpenDarwin project and will be also used in Mac OS X 10.5 Leopard for software installation routines (replacing gzipped pax files). With the release of Compress Files 3.0, now Mac OS X users have an easy to use tool to compress files in this new format.
