The following packages have been upgraded in the Cygwin distribution:

* gzip	1.11

GNU gzip is a popular data compression program, developed to
replace compress because of patents covering the LZW algorithm
at the time, with better compression as a bonus.

For more information see the project home pages:

	https://www.gnu.org/software/gzip/
	https://sv.gnu.org/projects/gzip/

For changes since the previous Cygwin release please see below or read
/usr/share/doc/gzip/NEWS after installation; for complete details see:

Noteworthy changes in release 1.11 (2021-09-03) [stable]

* Bug fixes
* Documentation improvements
* Performance improvements
* Infrastructure upgrades


Noteworthy changes in release 1.10 (2018-12-29) [stable]

* Changes in behavior

  Compressed gzip output no longer contains the current time as a
  timestamp when the input is not a regular file.  Instead, the output
  contains a null (zero) timestamp.  This makes gzip's behavior more
  reproducible when used as part of a pipeline.  (As a reminder, even
  regular files will use null timestamps after the year 2106, due to a
  limitation in the gzip format.)

* Bug fixes

  A use of uninitialized memory on some malformed inputs has been fixed.
  [bug present since the beginning]

  A few theoretical race conditions in signal handers have been fixed.
  These bugs most likely do not happen on practical platforms.
  [bugs present since the beginning]


Noteworthy changes in release 1.9 (2018-01-07) [stable]

* Bug fixes

  gzip -d -S SUFFIX file.SUFFIX would fail for any upper-case byte in SUFFIX.
  E.g., before, this command would fail:
    $ :|gzip > kT && gzip -d -S T kT
    gzip: kT: unknown suffix -- ignored
  [bug present since the beginning]

  When decompressing data in 'pack' format, gzip no longer mishandles
  leading zeros in the end-of-block code.  [bug introduced in gzip-1.6]

  When converting from system-dependent time_t format to the 32-bit
  unsigned MTIME format used in gzip files, if a timestamp does not
  fit gzip now substitutes zero instead of the timestamp's low-order
  32 bits, as per Internet RFC 1952.  When converting from MTIME to
  time_t format, if a timestamp does not fit gzip now warns and
  substitutes the nearest in-range value instead of crashing or
  silently substituting an implementation-defined value (typically,
  the timestamp's low-order bits).  This affects timestamps before
  1970 and after 2106, and timestamps after 2038 on platforms with
  32-bit signed time_t.  [bug present since the beginning]

  Commands implemented via shell scripts are now more consistent about
  failure status.  For example, 'gunzip --help >/dev/full' now
  consistently exits with status 1 (error), instead of with status 2
  (warning) on some platforms.  [bug present since the beginning]

  Support for VMS and Amiga has been removed.  It was not working anyway,
  and it reportedly caused file name glitches on MS-Windowsish platforms.
