Subject: bug#22900: new snapshot available: gzip-1.6.42-d6d4

From: Jim Meyering <[email-masked]>
Date: Thu, 3 Mar 2016 18:17:38 -0800

It has been over 2.5 years since the release of gzip-1.6,
so we're a bit overdue. I would like to make the 1.7
release in the next couple of weeks, so any testing
you can do with this snapshot would be most welcome.

Tarballs:
=======================
gzip snapshot:
  http://meyering.net/gzip/gzip-ss.tar.xz      744 KB
  http://meyering.net/gzip/gzip-ss.tar.xz.sig
  http://meyering.net/gzip/gzip-1.6.42-d6d4.tar.xz

Here are the current NEWS entries:
===============================
** Changes in behavior

  The GZIP environment variable is now obsolescent; gzip now warns if
  it is used, and rejects attempts to use dangerous options or operands.
  You can use an alias or script instead.

** New features

  gzip now accepts the --synchronous option, which causes it to use
  fsync and similar primitives to transfer output data to the output
  file's storage device when the file system supports this.  Although
  this option makes gzip safer in the presence of system crashes, it
  can make gzip considerably slower.

  gzip now accepts the --rsyncable option. This option is accepted in
  all modes, but has effect only when compressing: it makes the resulting
  output more amenable to efficient use of rsync.  For example, when a
  large input file gets a small change, a gzip --rsyncable image of
  that file will remain largely unchanged, too.  Without --rsyncable,
  even a tiny change in the input could result in a totally different
  gzip-compressed output file.

** Bug fixes

  gzip -k -v no longer reports that files are replaced.
  [bug present since the beginning]
