    Release Notes: This release fixes a deadlock due to unsynchronized broadcasts, prevents deletion of input files on error, adds more detailed kernel error messages, fixes error handling in muliti-file processing, and updates documentation on processing data from stdin.

      Release Notes: This release fixes excessive output permissions while compress/decompress is in progress. It now emulates the same behaviour as bzip2.

        Release Notes: This release fixes a hang on decompress with --ignore-trailing-garbage=1 when producer is interrupted on trailing garbage. It adds an example to help for decompression piped to tar, and fixes a typo in the Trailing Garbage printed message.

          Release Notes: This release fixes a hang on decompress with --ignore-trailing-garbage=1 when using more than 2 CPUs. The default extension on decompress of .tbz2 has been changed to .tar for bzip2 compatibility. Trailing garbage errors will now be printed even when in quiet mode.

            Release Notes: This release modifies Consumer_decompress throttling to prevent potential deadlock/infinite loops in certain situations. It also fixes a deadlock bug and performance issue when consumer is working with long bzip2 sequences. It fixes a bug which caused a hang while decompressing a prematurely truncated bzip2 stream and fixes a hang on decompression of some truncated archives. Finally, it implements an --ignore-trailing-garbage feature for non-standard archives such as gentoo packages.

              Release Notes: This release improves the decompression performance of long bzip2 streams of large single-stream bzip2 blocks. pbzip2 should now decompress files created with bzip2 at least as quickly as bzip2, or slightly faster. It also handles decompression of long bzip2 streams incrementally instead of loading whole streams in memory at once.

                Release Notes: This release adds support for multi-threaded decompression using STDIN/pipes and throttling compression to prevent memory exhaustion with slow output pipe. It fixes a bug that did not allow command line parameters to be used when compressing data from STDIN. It also contains major improvements to protection of shared variables, error and signal handling, and program termination, and many more minor enhancements and bugfixes.

                  Release Notes: This release properly complains about trying to read or write compressed data to the terminal, and exits. It further fixes the CPU detection crash, and the Makefile has been updated to force deletion when cleaning.

                    Release Notes: Support was added for using pbzip2 with tar and for all remaining bzip2 command line options, so pbzip2 can be used as a drop-in replacement for bzip2. A bug was fixed that would cause pbzip2 to crash if detection of the number of processors failed. Compiling with uclibc is now supported.

                      Release Notes: The ability to compress, decompress, and test data using stdin and pipes is now supported. Support was also added to directly decompress files without using threads when files are small, the system only has 1 CPU, or if the .bz2 file contains 1 bzip2 stream. This version can now compress 0 byte files like bzip2. Support for pbzcat symlink to automatically specify a decompression mode to stdout, just like bzcat, is now included.
