Facebook API version detection
<p>We recently received this alert from Facebook on our Unity App.</p>

<p><i>Your app has been making recent API calls to Graph API v2.0, which will reach the end of the 2-year deprecation window on Monday, August 8, 2016. Please migrate all calls to v2.1 or higher in order to avoid potential broken experiences.</i></p>

<p>The SDK version is 6.2.2 which should be on API 2.2 - 2.4.  </p>

<p>These are the APIs/Properties I'm using:</p>

<ol>
<li>FB.Init(OnFbInit, OnHideUnity); </li>
<li>FB.API("/me?fields=name", Facebook.HttpMethod.GET,GotFBData);</li>
<li>FB.IsLoggedIn; </li>
<li>FB.UserId</li>
<li>FB.AccessToken</li>
</ol>

<p>Why is Facebook saying we are using API 2.0? Is it safe to ignore?</p>

<p>Thanks,</p>
