@@ -3,7 +3,7 @@ About Little CMS
 Little CMS intends to be an OPEN SOURCE small-footprint color management engine, with special focus on accuracy and performance. It uses the International Color Consortium standard (ICC), which is the modern standard when regarding to color management. The ICC specification is widely used and is referred to in many International and other de-facto standards. It was approved as an International Standard, ISO 15076-1, in 2005. 
 
 Conformance
-Little CMS 2.12 is a FULL IMPLEMENTATION of ICC specification 4.3, it fully supports all kind of V2 and V4 profiles, including abstract, devicelink and named color profiles. Check the tutorial for a exhaustive list of features.
