	This release is primarily a bug-fix release.
	A complete list of bugs fixed in this version is available here:
	https://sv.gnu.org/bugs/index.php?group=make&report_id=111&fix_release_id=110&set=custom
	* WARNING: Backward-incompatibility!
	  In previous releases it was not well-defined when updates to MAKEFLAGS made
	  inside a makefile would be visible.  This release ensures they are visible
	  immediately, even when invoking $(shell ...) functions.  Also, command line
	  variable assignments are now always present in MAKEFLAGS, even when parsing
	  makefiles.
	  Implementation provided by Dmitry Goncharov <dgoncharov@users.sf.net>
	* New feature: Parallel builds of archives
	  Previously it was not possible to use parallel builds with archives.  It is
	  still not possible using the built-in rules, however you can now override
	  the built-in rules with a slightly different set of rules and use parallel
	  builds with archive creation.  See the "Dangers When Using Archives" section
	  of the GNU Make manual, and https://savannah.gnu.org/bugs/index.php?14927
	* Previously target-specific variables would inherit their "export" capability
	  from parent target-specific variables even if they were marked private.  Now
	  private parent target-specific variables have no affect.  For more details
	  see https://savannah.gnu.org/bugs/index.php?61463
	* Disable FIFO jobserver on GNU/Hurd and Cygwin
	  Experimentation shows that the new FIFO-based jobserver doesn't work well on
	  GNU/Hurd or Cygwin: revert these systems to use the pipe-based jobserver.
	* Updates to allow building on OS/2

	* New platform: GNU Make is supported on z/OS
	  Thanks to Igor Todorovski <itodorov@ca.ibm.com> for the patches and testing
	  assistance.
