GraphicsMagick 1.3.23 is now available

GraphicsMagick 1.3.23 is now available.  This release is primarily to 
fix a serious regression in the scale algorithm, but fixes several 
minor bugs as well.  The GraphicsMagick project strives to assure that 
each release is better than the one before it, but 1.3.22 included an 
unfortunate regression.  Tests have been added to the test suite to 
assure that this particular problem will not occur again.

The following are the change notes associated with this release:

1.3.23 (November 7, 2015)
==========================

Security Fixes:

* ScaleImage(): While not strictly a security issue, requesting to
   scale an image while retaining the original number of rows will lead
   to a program crash or memory corruption due to double-free.

Bug fixes:

* ScaleImage(): Fix problem with new width/height match original
   (regression added by 1.3.22).

* ScaleImage(): Fix double-free when new rows matches original rows
   (regression added by 1.3.22).

* MinGW build fix related to eliminating a sleep() macro which
   conflicts with a MinGW-provided inline sleep() function.

* PNG: Issue a warning instead of an error when attempting to read a
   PNG file containing a zero-length profile.  This allows the file to
   be read.

* identify: Fix problem in that `identify -format "%A"` (to test if
   transparency is supported in image) does not always produce the
   correct results.

New Features:

* None.

Feature improvements:

* None.

Performance Improvements:

* None.

Windows Delegate Updates/Additions:

* None.

Build Changes:

* Configure: Removed CFLAGS and LDFLAGS deduplication code which
   caused problems for user-provided CFLAGS and LDFLAGS which added and
   then removed compiler/linker options.  Specifically, this fixes a
   problem with creating OS X universal builds.

* Configure: Add tests for 'ps2write' and 'eps2write' which are
   available in recent Ghostscript.

Behavior Changes:

* None
