    <b>1.0.80.0 - April XX, 2012</b>
</p>
<ul>
    <li>In the SQLiteFunction class, when calling user-provided methods from a delegate called by native code, avoid throwing exceptions, optionally tracing the caught exceptions. Fix for [8a426d12eb].</li>
    <li>Add Visual Studio 2005 support to all the applicable solution/project files, their associated supporting files, and the test suite.</li>
    <li>Add Visual Studio 2005 support to the redesigned designer support installer.</li>
    <li>Add experimental support for &quot;pre-loading&quot; the native SQLite library based on the processor architecture of the current process.  This feature is now enabled by default at compile-time.</li>

    <li>Acquire and hold a static data lock while checking if the native SQLite library has been initialized to prevent a subtle race condition that can result in superfluous error messages. Fix for [72905c9a77].</li>
    <li>Support tracing of all parameter binding activity and use the connection flags to control what is traced.</li>
    <li>When converting a DateTime instance of an &quot;Unspecified&quot; kind to a string, use the same kind as the connection, if available.</li>
    <li>Add overload of the SQLiteDataReader.GetValues method that returns a NameValueCollection.</li>
    <li>Add static ToUnixEpoch method to the SQLiteConvert class to convert a DateTime value to the number of whole seconds since the Unix epoch.</li>
    <li>In the implicit conversion operators (to IntPtr) for both the SQLiteConnectionHandle and SQLiteStatementHandle classes, return IntPtr.Zero if the instance being converted is null.</li>
    <li>Write warning message to the active trace listners (for the Debug build configuration only) if a column type or type name cannot be mapped properly. See [4bbf851fa5].</li>
