+* 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.
+
+
+* Noteworthy changes in release 1.4 (2010-01-20) [stable]
+
+** Bug fixes
+
+  gzip -d could segfault and/or clobber the stack, possibly leading to
+  arbitrary code execution.  This affects x86_64 but not 32-bit systems.
+  This fixes CVE-2010-0001.
+  For more details, see http://bugzilla.redhat.com/554418
+
+  gzip -d would fail with a CRC error for some valid inputs.
+  So far, the only valid input known to exhibit this failure was
+  compressed "from FAT filesystem (MS-DOS, OS/2, NT)".  In addition,
+  to trigger the failure, your memcpy implementation must copy in
+  the "reverse" order.

-* 'gzip -f foo.gz' now creates a file foo.gz.gz instead of complaining.
-
 * It is now documented that gzip ignores case when examining file name
   extensions; for example, 'gzip test.Gz' (without -f) fails because
   the file name ends in '.Gz'.
