bzip2 is a freely available, patent free (see below), high-quality data compressor. It typically compresses files to within 10% to 15% of the best available techniques (the PPM family of statistical compressors), whilst being around twice as fast at compression and six times faster at decompression.The code is organised as a library with a programming interface. The bzip2 program itself is a client of the library. You can use the library to compress data in memory using the bzip2 algorithms or you can use it in your own programs, to directly read and write .bz2 files.What\'s New in This Release: [ read full changelog ]· Security fix only.· Fixes CERT-FI 20469 as it applies to bzip2.
