 GNU gzip NEWS                                    -*- outline -*-
 
+* Noteworthy changes in release 1.6 (2013-06-09) [stable]
+
+** New features
+
+  gzip now accepts the --keep (-k) option, for consistency with tools
+  like xz, lzip and bzip2.  With this option, gzip no longer removes
+  named input files when compressing or decompressing.
+
+** Bug fixes
+
+  gzip -d no longer malfunctions with certain invalid data in 'pack' format.
+  [bug introduced in gzip-0.8]
+
+  When overwriting, gzip no longer acts as if you typed "y" when you type "n",
+  on some platforms when compiled with optimization.
+  [bug introduced in gzip-1.3.6]
+
+  zgrep no longer malfunctions with a multi-digit context option like -15.
+  Now, it passes that option to grep (equivalent to -C15) just as it does
+  for single-digit options. [bug introduced in gzip-1.3.12]
+
+  zmore now acts more like 'more', and is more portable to POSIXish hosts.
+
+
+* 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.
