This security issue was fixed:

- Fixed an out-of-bounds heap read in Type_MLU_Read that could be triggered by an untrusted image with a crafted ICC profile (boo#1021364).

These non-security issues were fixed:

* Fixed many typos in comments, thanks to Stefan Weil for doing that.
* Fixed localization bug, added a new test case crayons.icc thnaks to Richard Hughes for providing the profile.
* Fixed a bug in optimizer that made some formats (i.e, bits planar) unavailable
* Fixed misalignment problems on Alpha. The compiler does not align strings, and accessing begin of string as a uint16 makes code to fail.
* Added some extra checks to the tools and examples.
* Fix a bug that prevented to read luminance tag
* BIG amount of functionality contributed/Sponsored by Alien Skin Software: TransformStride, copyAlpha, performance plug-ins. Fixes some warnings as well.
* added an extra _ to _stdcall to make it more portable
* Fixed a bug in transicc for named color profiles
* Fixed several compiler warnings
* Added support for Visual Studio 2015
* Fixed for XCODE project
