Release Notes: Plzip now shows the progress of compression at verbosity level 2 (-vv). Signals "SIGUSR1" and "SIGUSR2" are no longer raised internally to signal a fatal error.
Release Notes: Scalability of compression (maximum number of useful worker threads) has been increased. Scalability when decompressing from/to regular files has been increased. The number of worker threads is now limited to the number of members in the input file when decompressing from a regular file. The target "install-as-lzip" has been added to the Makefile.
Release Notes: The option "-F, --recompress", which forces recompression of files whose name already has the ".lz" or ".tlz" suffix, has been added. The options "-d, --decompress" and "-t, --test" now also show compression ratio. Stdin and stdout are now set in binary mode on OS2.
Release Notes: Match length limits set by options -1 to -9 have been changed to match those of lzip 1.11. A limit has been set on the number of packets produced by decompressor worker threads to limit the amount of memory used. Do not show the message "and `--stdout' was not specified" for file types that can't be read (directories, etc). A warning about fchown's return value being ignored has been fixed.
Release Notes: Some small portability problems have been fixed. The chapter "Program Design" and a description of the option "--threads" have been added to the manual.
Release Notes: Parallel decompression has been implemented.
Release Notes: The option "--version" now shows the version of lzlib being used. A code reorganization has been made. The new class "Packet_courier" now coordinates data movement and synchronization among threads.
Release Notes: The "--data-size" option has been added. The output file is now removed if plzip is interrupted. This version automatically chooses the smallest possible dictionary size for each member during compression, saving memory during decompression. Regular files are now opened in binary mode on non-POSIX platforms defining the O_BINARY macro.
Release Notes: The lzip options "--dictionary-size" and "--match-length" have been implemented.
