+notes on raylib 1.5
+-------------------
+
+On July 2016, after 5 months of raylib 1.4 release, arrives raylib 1.5. This new version is the biggest boost of the library until now, lots of parts of the library have been redesigned, lots of bugs have been solved and some **AMAZING** new features have been added.
+
+VR support: raylib supports **Oculus Rift CV1**, one of the most anticipated VR devices in the market. Additionally, raylib supports simulated VR stereo rendering, independent of the VR device; it means, raylib can generate stereo renders with custom head-mounted-display device parameteres, that way, any VR device in the market can be **simulated in any platform** just configuring device parameters (and consequently, lens distortion). To enable VR is [extremely easy](https://github.com/raysan5/raylib/blob/develop/examples/core_oculus_rift.c).
+
+New materials system: now raylib supports standard material properties for 3D models, including diffuse-ambient-specular colors and diffuse-normal-specular textures. Just assign values to standard material and everything is processed internally.
+
+New lighting system: added support for up to 8 configurable lights and 3 light types: **point**, **directional** and **spot** lights. Just create a light, configure its parameters and raylib manages render internally for every 3d object using standard material.
+
+Complete gamepad support on Raspberry Pi: Gamepad system has been completely redesigned. Now multiple gamepads can be easily configured and used; gamepad data is read and processed in raw mode in a second thread.
+
+Redesigned physics module: [physac](https://github.com/raysan5/raylib/blob/develop/src/physac.h) module has been converted to header only and usage [has been simplified](https://github.com/raysan5/raylib/blob/develop/examples/physics_basic_rigidbody.c). Performance has also been singnificantly improved, now physic objects are managed internally in a second thread.
+
+Audio chiptunese support and mixing channels: Added support for module audio music (.xm, .mod) loading and playing. Multiple mixing channels are now also supported. All this features thanks to the amazing work of @kd7tck.
+
+Other additions include a [2D camera system](https://github.com/raysan5/raylib/blob/develop/examples/core_2d_camera.c), render textures for offline render (and most comprehensive [postprocessing](https://github.com/raysan5/raylib/blob/develop/examples/shaders_postprocessing.c)) or support for legacy OpenGL 2.1 on desktop platforms.
+
+This new version is so massive that is difficult to list all the improvements, most of raylib modules have been reviewed and [rlgl](https://github.com/raysan5/raylib/blob/develop/src/rlgl.c) module has been completely redesigned to accomodate to new material-lighting systems and stereo rendering. You can check [CHANGELOG](https://github.com/raysan5/raylib/blob/develop/CHANGELOG) file for a more detailed list of changes.
+
+Up to 8 new code examples have been added to show the new raylib features and also some samples to show the usage of [rlgl](https://github.com/raysan5/raylib/blob/develop/examples/rlgl_standalone.c) and [audio](https://github.com/raysan5/raylib/blob/develop/examples/audio_standalone.c) raylib modules as standalone libraries.

+/**********************************************************************************************
+*
+*   raylib 1.5.0 (www.raylib.com)
+*
+*   A simple and easy-to-use library to learn videogames programming
+*
+*   Features:
+*     Library written in plain C code (C99)
+*     Uses C# PascalCase/camelCase notation
+*     Hardware accelerated with OpenGL (1.1, 2.1, 3.3 or ES 2.0)
+*     Unique OpenGL abstraction layer (usable as standalone module): [rlgl]
+*     Powerful fonts module with SpriteFonts support (XNA bitmap fonts, AngelCode fonts, TTF)
+*     Multiple textures support, including compressed formats and mipmaps generation
+*     Basic 3d support for Shapes, Models, Billboards, Heightmaps and Cubicmaps
+*     Materials (diffuse, normal, specular) and Lighting (point, directional, spot) support
+*     Powerful math module for Vector, Matrix and Quaternion operations [raymath]
+*     Audio loading and playing with streaming support and mixing channels (WAV, OGG, XM, MOD)
+*     VR stereo rendering support with configurable HMD device parameters
+*     Multiple platforms support: Windows, Linux, Mac, Android, Raspberry Pi, HTML5 and Oculus Rift CV1
+*     Custom color palette for fancy visuals on raywhite background
+*     Minimal external dependencies (GLFW3, OpenGL, OpenAL)
+*
+*   Used external libs:
+*     GLFW3 (www.glfw.org) for window/context management and input
+*     GLAD for OpenGL extensions loading (3.3 Core profile, only PLATFORM_DESKTOP)
+*     stb_image (Sean Barret) for images loading (JPEG, PNG, BMP, TGA, PSD, GIF, HDR, PIC)
+*     stb_image_write (Sean Barret) for image writting (PNG)
+*     stb_vorbis (Sean Barret) for ogg audio loading
+*     stb_truetype (Sean Barret) for ttf fonts loading
+*     jar_xm (Joshua Reisenauer) for XM audio module loading
+*     jar_mod (Joshua Reisenauer) for MOD audio module loading
+*     OpenAL Soft for audio device/context management
+*     tinfl for data decompression (DEFLATE algorithm)
+*
+*   Some design decisions:
+*     32bit Colors - All defined color are always RGBA (struct Color is 4 byte)
+*     One custom default font is loaded automatically when InitWindow()
+*     If using OpenGL 3.3 or ES2, several vertex buffers (VAO/VBO) are created to manage lines-triangles-quads
+*     If using OpenGL 3.3 or ES2, two default shaders are loaded automatically (internally defined)

 *
-*   raylib 1.2 (www.raylib.com)
+*   raylib 1.5.0 (www.raylib.com)
 *
 *   A simple and easy-to-use library to learn videogames programming
 *
 *   Features:
 *     Library written in plain C code (C99)
 *     Uses C# PascalCase/camelCase notation
-*     Hardware accelerated with OpenGL (1.1, 3.3+ or ES2)
-*     Unique OpenGL abstraction layer [rlgl]
-*     Powerful fonts module with SpriteFonts support
-*     Multiple textures support, including DDS and mipmaps generation
-*     Basic 3d support for Shapes, Models, Heightmaps and Billboards
-*     Powerful math module for Vector and Matrix operations [raymath]
-*     Audio loading and playing with streaming support (WAV and OGG)
-*     Multiplatform support, including Android devices, Raspberry Pi and HTML5
+*     Hardware accelerated with OpenGL (1.1, 2.1, 3.3 or ES 2.0)
+*     Unique OpenGL abstraction layer (usable as standalone module): [rlgl]
+*     Powerful fonts module with SpriteFonts support (XNA bitmap fonts, AngelCode fonts, TTF)
+*     Multiple textures support, including compressed formats and mipmaps generation
+*     Basic 3d support for Shapes, Models, Billboards, Heightmaps and Cubicmaps
+*     Materials (diffuse, normal, specular) and Lighting (point, directional, spot) support
+*     Powerful math module for Vector, Matrix and Quaternion operations [raymath]
+*     Audio loading and playing with streaming support and mixing channels (WAV, OGG, XM, MOD)
+*     VR stereo rendering support with configurable HMD device parameters
+*     Multiple platforms support: Windows, Linux, Mac, Android, Raspberry Pi, HTML5 and Oculus Rift CV1
+*     Custom color palette for fancy visuals on raywhite background
+*     Minimal external dependencies (GLFW3, OpenGL, OpenAL)
 *
 *   Used external libs:
 *     GLFW3 (www.glfw.org) for window/context management and input
-*     GLEW for OpenGL extensions loading (3.3+ and ES2)
+*     GLAD for OpenGL extensions loading (3.3 Core profile, only PLATFORM_DESKTOP)
 *     stb_image (Sean Barret) for images loading (JPEG, PNG, BMP, TGA, PSD, GIF, HDR, PIC)
 *     stb_image_write (Sean Barret) for image writting (PNG)
 *     stb_vorbis (Sean Barret) for ogg audio loading
+*     stb_truetype (Sean Barret) for ttf fonts loading
+*     jar_xm (Joshua Reisenauer) for XM audio module loading
+*     jar_mod (Joshua Reisenauer) for MOD audio module loading
 *     OpenAL Soft for audio device/context management
 *     tinfl for data decompression (DEFLATE algorithm)
 *
 *   Some design decisions:
-*     32bit Colors - All defined color are always RGBA
-*     32bit Textures - All loaded images are converted automatically to RGBA textures
-*     SpriteFonts - All loaded sprite-font images are converted to RGBA and POT textures
+*     32bit Colors - All defined color are always RGBA (struct Color is 4 byte)
 *     One custom default font is loaded automatically when InitWindow()
-*     If using OpenGL 3.3+ or ES2, one default shader is loaded automatically (internally defined)
+*     If using OpenGL 3.3 or ES2, several vertex buffers (VAO/VBO) are created to manage lines-triangles-quads
+*     If using OpenGL 3.3 or ES2, two default shaders are loaded automatically (internally defined)

+*
+*   raylib 1.5.0 (www.raylib.com)
+*
+*   A simple and easy-to-use library to learn videogames programming
+*
+*   Features:
+*     Library written in plain C code (C99)
+*     Uses C# PascalCase/camelCase notation
+*     Hardware accelerated with OpenGL (1.1, 2.1, 3.3 or ES 2.0)
+*     Unique OpenGL abstraction layer (usable as standalone module): [rlgl]
+*     Powerful fonts module with SpriteFonts support (XNA bitmap fonts, AngelCode fonts, TTF)
+*     Multiple textures support, including compressed formats and mipmaps generation
+*     Basic 3d support for Shapes, Models, Billboards, Heightmaps and Cubicmaps
+*     Materials (diffuse, normal, specular) and Lighting (point, directional, spot) support
+*     Powerful math module for Vector, Matrix and Quaternion operations [raymath]
+*     Audio loading and playing with streaming support and mixing channels (WAV, OGG, XM, MOD)
+*     VR stereo rendering support with configurable HMD device parameters
+*     Multiple platforms support: Windows, Linux, Mac, Android, Raspberry Pi, HTML5 and Oculus Rift CV1
+*     Custom color palette for fancy visuals on raywhite background
+*     Minimal external dependencies (GLFW3, OpenGL, OpenAL)
+*
+*   Used external libs:
+*     GLFW3 (www.glfw.org) for window/context management and input
+*     GLAD for OpenGL extensions loading (3.3 Core profile, only PLATFORM_DESKTOP)
+*     stb_image (Sean Barret) for images loading (JPEG, PNG, BMP, TGA, PSD, GIF, HDR, PIC)
+*     stb_image_write (Sean Barret) for image writting (PNG)
+*     stb_vorbis (Sean Barret) for ogg audio loading
+*     stb_truetype (Sean Barret) for ttf fonts loading
+*     jar_xm (Joshua Reisenauer) for XM audio module loading
+*     jar_mod (Joshua Reisenauer) for MOD audio module loading
+*     OpenAL Soft for audio device/context management
+*     tinfl for data decompression (DEFLATE algorithm)
+*
+*   Some design decisions:
+*     32bit Colors - All defined color are always RGBA (struct Color is 4 byte)
+*     One custom default font is loaded automatically when InitWindow()
+*     If using OpenGL 3.3 or ES2, several vertex buffers (VAO/VBO) are created to manage lines-triangles-quads
+*     If using OpenGL 3.3 or ES2, two default shaders are loaded automatically (internally defined)

-/**********************************************************************************************
-*
-*   raylib 1.2 (www.raylib.com)
-*
-*   A simple and easy-to-use library to learn videogames programming
-*
-*   Features:
-*     Library written in plain C code (C99)
-*     Uses C# PascalCase/camelCase notation
-*     Hardware accelerated with OpenGL (1.1, 3.3+ or ES2)
-*     Unique OpenGL abstraction layer [rlgl]
-*     Powerful fonts module with SpriteFonts support
-*     Multiple textures support, including DDS and mipmaps generation
-*     Basic 3d support for Shapes, Models, Heightmaps and Billboards
-*     Powerful math module for Vector and Matrix operations [raymath]
-*     Audio loading and playing with streaming support (WAV and OGG)
-*     Multiplatform support, including Android devices, Raspberry Pi and HTML5
-*
-*   Used external libs:
-*     GLFW3 (www.glfw.org) for window/context management and input
-*     GLEW for OpenGL extensions loading (3.3+ and ES2)
-*     stb_image (Sean Barret) for images loading (JPEG, PNG, BMP, TGA, PSD, GIF, HDR, PIC)
-*     stb_image_write (Sean Barret) for image writting (PNG)
-*     stb_vorbis (Sean Barret) for ogg audio loading
-*     OpenAL Soft for audio device/context management
-*     tinfl for data decompression (DEFLATE algorithm)
-*
-*   Some design decisions:
-*     32bit Colors - All defined color are always RGBA
-*     32bit Textures - All loaded images are converted automatically to RGBA textures
-*     SpriteFonts - All loaded sprite-font images are converted to RGBA and POT textures
-*     One custom default font is loaded automatically when InitWindow()
-*     If using OpenGL 3.3+ or ES2, one default shader is loaded automatically (internally defined)
