title: Newest C++ compiler in Visual Studio
body: <p>In my early Linux days things were easy: I just could install the newest gcc-compiler and everything was fine. In contrast, Visual Studio confuses me a bit with it's <a href="http://www.visualstudio.com/en-us/downloads/visual-studio-2015-downloads-vs" rel="nofollow">various download options</a>, whereas all I want is the newest C++ compiler in order to apply C++11 and C++14 features -- and that preferably without having to download gigabites of data. Can somebody help me with this issue?</p>
  
  <p>Currently I use the free version of VS 2013 with the November 2013 CTP compiler.</p>
  
  <ul>
  <li>How new does the compiler get when staying in VS 2013 (until the official VS 2015 comes out)?</li>
  <li>Are there some "good practices" for switching to VS 2015 CTP? Is there also a free version (I only recognized the Ultimate version so far)? When I install this VS 2015 CTP, do I have to download the whole official stuff again once it is released, or can I update?</li>
  </ul>
