it to extend its functionality, but the core engine's source is not changed.</p>
<p>
</p>

<h2><b>Version History</b></h2>

<p>
    <b>1.0.83.0 - November XX, 2012</b>
</p>
<ul>
    <li>Updated to <a href="http://www.sqlite.org/src/info/trunk">SQLite 3.7.15</a>.</li>
    <li>Add Visual Studio 2012 support to all the applicable solution/project files, their associated supporting files, and the test suite.</li>
    <li>Add Visual Studio 2012 support to the redesigned designer support installer.</li>
    <li>Allow opened connections to skip adding the extension functions included in the interop assembly via the new NoExtensionFunctions connection flag.</li>
    <li>Support loading of SQLite extensions via the new EnableExtensions and LoadExtension methods of the SQLiteConnection class. Pursuant to [17045010df].</li>
