-Page Update: **18/03/2017**
+Page Update: **01/04/2017**
Library Version: **2.0.0** (see **[Build Status](https://github.com/andrewssobral/bgslibrary/wiki/Build-status)** and **[Release Notes](https://github.com/andrewssobral/bgslibrary/wiki/Release-notes)** for more info)
-The **BGSLibrary** was developed by [Andrews Sobral](http://andrewssobral.wixsite.com/home) and provides an easy-to-use C++ framework based on [OpenCV](http://www.opencv.org/) to perform foreground-background separation in videos. The bgslibrary is compatible with OpenCV 2.x and 3.x, and compiles under Windows, Linux, and Mac OS X. Currently the library contains **40** algorithms. The source code is available under [GNU GPLv3 license](https://www.gnu.org/licenses/gpl-3.0.en.html), the library is free and open source for academic purposes.
