modules/lcms/NEWS

+
+ New in ver 1.17
+ ===============
+  
+Changes in API
+----------------------
+
+WIN64 support
+_vsnprintf wrap
+BOOL replaced by LCMSBOOL
+cmsSetLanguage parameters changed to match ICC spec
+removed support for extended gamut descriptor (was never fully implemented)
+cmsFLAGS_NODEFAULTRESOURCEDEF moved to 0x01000000
+_cmsMalloc wrapper for malloc
+_cmsFree wrapper for free
+
+
+Implementation
+----------------------
+All errors moved to fatal, since there is no easy recovery strategy
+Vulnerability fixes on cmsio1.c 
+Status check, many functions now check the status when calling other functions. Improved robustness against ill-formed profiles.
+_cmsSaveProfile didn't copy tags from a file based profile, fixed.
+
+
+Utilities
+----------
+icctrans: CMYKcm support wrongly implemented, fixed.
+icclink: linking 3 to 7 channels didn't work in some cases, fixed.
+

+ The lcms library is now distributed under

+                MIT PUBLIC LICENSE
+
+ See file COPYING. for details
+
+
+   This is the 15th. public release the engine. It has been tested 
+   across several versions before, but it is possible some
+   bugs still arises. If so, sorry for the inconvenience, and
+   please feel free to submit any suggestion/solution (if you can
+   found it) at:
+
+                       info@littlecms.com
+
+ 
+   Note that the aesthetics of resulting colors are due only to
+   profiles, and not as consequence of the lcms package.
+
+   The main site for the package is located at
+
+           http://www.littlecms.com
+        or
+           http://www.lcms.coloraid.de
+
+
+   Littlecms has also a mailing list on:
+
+   http://lists.sourceforge.net/lists/listinfo/lcms-user
+
+
+   Looking forward the lcms project would grow in future, I will 
+   welcome any contribution/optimization/enhancement.
+
+   Enjoy!
+
+
+  About profiles
+  ==============
+
+    The demo of this package includes some profiles for colorspace
+    conversions. I figure all of them are in public domain, but
+    since some contains copyright notice, I will enumerate here
+    the sources:
+
+         Sun Microsystems Java SDK (widely available)
+         Kodak public FTP site: ftp.kodak.com
+         ICM Stress demo from microsoft. www.microsoft.com
+         sRGB from sRGB site www.srgb.com
+
+    If you found any of these not to be in public domain,
+    please notify me. I will remove the offending profile as soon as
+    posible.
+
+
+
+  Additional files
+  ================
+
+    ICC34.h is the header file the International Color Consortium
+    has posted for version spec 3.4, with some minor modifications
+    for improving portability.
+
+    You can reach it at
+
+                http://www.color.org
