Release Notes: The shell script test.sh tests the installed instance of lbzip2, which can be different from the currently built one. pbzip2 is not a requirement for testing anymore, but test.sh will try to measure its performance if it's available. The same applies to the bzip2 module of 7za (from p7zip). Some GNU/Linux specific hints on enabling SUSv2 conformance (which is required for building and testing) were added to the README.
Release Notes: This version fixes two major bugs introduced in 2.4, which could have resulted in assertion failure or poor compression performance.
Release Notes: This release introduces a sequential mode of operation which is not used by default, but can be activated with a commandline switch. This new mode usually improves the compression ratio and decreases CPU usage at the cost of degraded scalability. This release also fixes several minor bugs.
Release Notes: This release adds a new feature: When decompressing with both --force and --stdout options given, lbzip2 will copy files which are not in bzip2 format, instead of reporting an invalid file format. This release also fixes several minor bugs.
Release Notes: The decompressor was made more bzip2-compatible. All valid bzip2 files should now be properly decompressed by lbzip2. Memory allocation was reduced significantly. Compression performance was improved by the inclusion of new block-sorting code using the divsufsort algorithm. This version also fixes a few other minor bugs.
Release Notes: This release fixes a use-after-free security vulnerability introduced in version 2.0. All users are recommended to update to version 2.1.
