About:
bzip2 is a portable, lossless data compressor based on the Burrows-Wheeler transform. It achieves good compression and runs on practically every (32/64-bit) platform in the known universe. The compression engine is also available as a library (libbz2), should you desire a programmatic interface.

Release focus: Major security fixes

Changes:
This release removes a potential security vulnerability which caused bzip2 to fail one of the test cases provided and reported in CERT-FI 20469. Upgrading is strongly recommended.

[»] progress patch
by Folkert van Heusden - Jan 20th 2003 11:15:41

Hi,

I wrote a patch which shows a progress indicator (how much done/new size) while compressing and decompressing.
You can find it here: http://www.vanheusden.com/Linux/
