 ### Sending a Pull-Request
 
-To send a pull-request, first of all, make sure you're sending it to [develop branch](https://github.com/raysan5/raylib/tree/develop). Here are some other rules:
-
  - Make sure the PR description clearly describes the problem and solution. Include the relevant issue number if applicable.
  - Don't send big pull-requests (lots of changelists), they are difficult to review. It's better to send small pull-request, one at a time.
  - Verify that changes don't break the build (at least on Windows platform). As many platforms where you can test it, the better, but don't worry

+notes on raylib 2.0
+-------------------
+
+It's been 9 month since last raylib version was published, a lots of things have changed since then... This new raylib version represents an inflexion point in the development of the library and so, we jump to a new major version... Here it is the result of almost **5 years and thousands of hours of hard work**... here it is... **raylib 2.0**
+
+In **raylib 2.0** the full API has been carefully reviewed for better consistency, some new functionality has been added and the overall raylib experience has been greatly improved... The key features of new version are:
+
+**Complete removal of external dependencies.** Finally, raylib does not require external libraries to be installed and linked along with raylib, all required libraries are contained and compiled within raylib. Obviously some external libraries are related but only the strictly platform-dependant required ones, that comes installed with the OS. So, raylib becomes a self-contained platform-independent games development library. 
+
+**Full redesign of audio module to use the amazing mini_al audio library**, along with external dependencies removal, OpenAL library has been replaced by mini_al, this brand new library offers automatic dynamic linking with default OS audio systems. Undoubtly, the perfect low-level companion for raylib audio module!
+
+**Support for continuous integration building*** through AppVeyor and Travis CI. As a consequence, raylib GitHub develop branch has been completely removed simplyfing the code-base to a single master branch, always stable. Every time a new commit is deployed, library is compiled for **up-to 12 different configurations**, including multiple platforms, 32bit/64bit and multiple compiler options! All those binaries are automatically attached to any new release!
+
+**More platforms supported and tested**, including BSD family (FreeBSD, openBSD, NetBSD, DragonFly) and Linux-based family platforms (openSUSE, Debian, Ubuntu, Arch, NixOS...). raylib has already been added to some package managers! Oh, and last but not less important, **Android 64bit** is already supported by raylib!
+
+**Support for TCC compiler!** Thanks to the lack of external dependencies, raylib can now be easily compiled with a **minimal toolchain**, like the one provide by Tiny C Compiler. It opens the door to an amazing future, allowing, for example, static linkage of libtcc for **runtime compilation of raylib-based code**... and the library itself if required! Moreover, TCC is blazing fast, it can compile all raylib in a couple of seconds!
+
+Refactored all raylib configuration #defines into a **centralized `config.h` header**, with more than **40 possible configuration options** to compile a totally customizable raylib version including only desired options like supported file-formats or specific functionality support. It allows generating a trully ligth-weight version of the library if desired!
+
+A part of that, lots of new features, like a brand **new font rendering and packaging system** for TTF fonts with **SDF support** (thanks to the amazing STB headers), new functions for **CPU image data manipulation**, new orthographic 3d camera mode, a complete review of `raymath.h` single-file header-only library for better consistency and performance, new examples and way, [way more](https://github.com/raysan5/raylib/blob/master/CHANGELOG).
+
+Probably by now, **raylib 2.0 is the simplest and easiest-to-use library to learn (and understand) videogames programming**... but, undoubtly its development has exceeded any initial objective; raylib has become a simple and easy-to-use trully multiplatform portable standalone media library with thousands of possibilities... and that's just the beginning!

+*   rlgl - raylib OpenGL abstraction layer
+*
+*   rlgl is a wrapper for multiple OpenGL versions (1.1, 2.1, 3.3 Core, ES 2.0) to
+*   pseudo-OpenGL 1.1 style functions (rlVertex, rlTranslate, rlRotate...).
+*
+*   When chosing an OpenGL version greater than OpenGL 1.1, rlgl stores vertex data on internal
+*   VBO buffers (and VAOs if available). It requires calling 3 functions:
+*       rlglInit()  - Initialize internal buffers and auxiliar resources
+*       rlglDraw()  - Process internal buffers and send required draw calls
+*       rlglClose() - De-initialize internal buffers data and other auxiliar resources
+*
+*   CONFIGURATION:
+*
+*   #define GRAPHICS_API_OPENGL_11
+*   #define GRAPHICS_API_OPENGL_21
+*   #define GRAPHICS_API_OPENGL_33
+*   #define GRAPHICS_API_OPENGL_ES2
+*       Use selected OpenGL graphics backend, should be supported by platform
+*       Those preprocessor defines are only used on rlgl module, if OpenGL version is
+*       required by any other module, use rlGetVersion() tocheck it
+*

+*       raymath.h - 3D math library (required by rlgl)
