The following package has been upgraded in the Cygwin distribution:

* gzip	1.13

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:

Noteworthy changes in release 1.13	2023-08-19

Changes in behavior

- zless now diagnoses gzip failures, if using less 623 or later.

- When SIGPIPE is ignored, gzip now exits with status 2 (warning)
  instead of status 1 (error) when writing to a broken pipe.  This is
  more useful with programs like 'less' that treat gzip exit status 2
  as a non-failure.

Bug fixes

- 'gzip -d' no longer fails to report invalid compressed data
  that uses a dictionary distance outside the input window.
  [bug present since the beginning]

- Port to C23, which does not allow K&R-style function definitions
  with parameters, and which does not define __alignas_is_defined.
