pigz users,

pigz version 2.3 has been released and is now available at http://zlib.net/pigz/ .  The main changes since 2.3 are:

- Don't complain about missing suffix when not writing output file
- Do not decompress concatenated zlib streams -- only gzip streams
- Add option for compression level 11 to use zopfli
- Fix handling of junk after compressed data

The -11 compression level uses a new deflate compressor called zopfli, from researchers at Google.  This compressor provides a few more percent compression, but at a severe cost in compression time of one to two orders of magnitude.  It should only be used when the compression is done once, but the decompression is done many times.

Mark
