+-----------------------------------------------
+Release:     raylib 1.8.0 (Oct 2017)
+-----------------------------------------------
+NOTE: 
+  In this release, multiple parts of the library have been reviewed again for consistency and simplification. 
+  It exposes more than 20 new functions in comparison with previous version and it improves overall programming experience.
+  
+BIG CHANGES:
+  - Image generation functions: Gradient, Checked, Noise, Cellular...
+  - Mesh generation functions: Cube, Sphere, Cylinder, Torus, Knot...
+  - New Shaders and Materials systems to support PBR materials
+  - Custom Android toolchain for APK building with simple Makefile
+  - Complete review of raymath functionality (Matrix, Quaternion)
+  - Complete review of rlgl layer functionality
+
+detailed changes:
