Jim [on behalf of the gzip maintainers]

Here is the GNU gzip home page:

For a summary of changes and contributors, see:;a=shortlog;h=v1.5
or run this command from a git-cloned gzip directory:
  git shortlog v1.4..v1.5

To summarize the 4107 gnulib-related changes, run these commands
- From a git-cloned gzip directory:
  git checkout v1.5
  git submodule summary v1.4

Here are the compressed sources:   (1.1MB)   (708KB)

Here are the GPG detached signatures[*]:

Use a mirror for higher download bandwidth:

[*] Use a .sig file to verify that the corresponding file (without the
.sig suffix) is intact.  First, be sure to download both the .sig file
and the corresponding tarball.  Then, run a command like this:

  gpg --verify gzip-1.5.tar.gz.sig

If that command fails because you don't have the required public key,
then run this command to import it:

  gpg --keyserver --recv-keys 7FD9FCCB000BEEEE

and rerun the 'gpg --verify' command.

This release was bootstrapped with the following tools:
  Autoconf 2.69.4-560f
  Automake 1.12a
  Gnulib v0.0-7450-g5eae670


* Noteworthy changes in release 1.5 (2012-06-17) [stable]

** Bug fixes

  gzip -d now decodes and checks header CRC16 checksums as specified by
  the FHCRC section of Internet RFC 1952.

  "gzip -d -S '' precious.gz" is now rejected immediately.  Before,
  that command would emulate "rm -i precious.gz", but with an easily-
  misunderstood prompt.  I.e., gzip would ask if it's ok to remove the
  existing file, "precious.gz".  If you made the mistake of saying "yes",
  it would remove that input file before attempting to uncompress it.

  gzip -cdf now properly handles input consisting of gzip'd data followed
  by uncompressed data.  Before it would output raw compressed input, too.
  For example, now "(printf x|gzip; echo y)|gzip -dcf" prints "xy\n",
  while before it would print "x<compressed data>y\n".

  gzip -rf no longer compresses files more than once (e.g., replacing
  FOO with FOO.gz.gz) on file systems such as ZFS where a readdir
  loop that unlinks and creates files can revisit output files.
