improves multi threading, adds contexts and a new locking plug-in type, among bugfixes and other minor features. If you run lcms in multiple threads, upgrading to this version is highly recommended.

User defined parametric curves can now be saved in ICC profiles.
RGB profiles using same tone curves for several channels are storing now only one copy of the curve (saves space)
Fixed a multithead bug on optimization (StageDEF)
Fixed some 64 bit warnings on size_t to uint32 conversions
update black point detection algorithm to reflect ICC changes
Added new cmsPlugInTHR() and fixed some race conditions (thanks to Artifex)
Added error descriptions on cmsSmoothToneCurve
Fixed a bug on big endian platforms not supporting uint64 or long long.
Fixed some bugs on floating point curves.
Several improvements in cgats parser.
Several minor issues found by cppcheck
Fixed devicelink generation for 8 bits
Added a reference for Mac MLU tag
Added a way to read the profile creator from header
Added identity curves support for write V2 LUT
More changes from Artifex
Added TIFF Lab16 handling on tifficc
Added some fixes from XhmikosR
Fixed a bug in parametric curves
Remove spurious tabs added by git merge of pull request
Added support for VS2012
Added a simple project for cppcheck
Rendering intent used when creating the transform is now propagated to profile header in cmsTransform2Devicelink. This is because 7.2.15 in spec 4.3
Transform2Devicelink now keeps white point when guessing deviceclass is enabled
Added some checks for non-happy path, mostly failing mallocs

a) tiff update to 4.0 (shlib major change)
b) glib2 update 2.30.2 (adds libffi dependency to buildlink3.mk)
Enjoy.
