Version 2.0 of Lbzip2

Release Notes: In this release, lbzip2 writes a single compressed stream per bz2 file instead of multiple concatenated streams. It doesn't decompress streams embedded within trailing garbage. It detects and rejects more kinds of invalid bz2 files. Relying on the independent bzip2 stack written by the new maintainer, lbzip2-2.0 features significantly improved (de)compression speed and robustness. In verbose mode, the compression ratio and progress information is displayed for each file. Decompression failures result in more detailed messages now. Lbzip2-2.x is licensed under the GPL v3.0 or any later version.

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.
