    <p><b>1.0.100.0 - April XX, 2016 <font color="red">(release scheduled)</font></b></p>
    <ul>
      <li>Updated to <a href="https://www.sqlite.org/draft/releaselog/3_12_0.html">SQLite 3.12.0</a>.</li>
      <li>Support compiling and using the interop assembly on Linux and Mac OS X.</li>
      <li>Support running the test suite under Mono on Linux and Mac OS X.</li>
      <li>Properly handle NULL values in the &quot;name&quot; column of the results returned by PRAGMA index_info(). Fix for <a href="https://system.data.sqlite.org/index.html/info/5251bd0878">[5251bd0878]</a>.</li>
      <li>For column types that resolve to boolean, recognize case-insensitive prefixes of &quot;True&quot; and &quot;False&quot;. Fix for <a href="https://system.data.sqlite.org/index.html/info/dbd65441a5">[dbd65441a5]</a>.</li>
      <li>Add NoVerifyTextAffinity connection flag to skip type affinity checking when fetching a column value as a string. Pursuant to <a href="https://system.data.sqlite.org/index.html/info/dbd65441a5">[dbd65441a5]</a>.</li>
      <li>The UnixEpoch DateTime format should use Int64 internally, not Int32.&nbsp;<b>** Potentially Incompatible Change **</b></li>
      <li>Avoid using Path.Combine with null values in the native library pre-loader. Fix for <a href="https://system.data.sqlite.org/index.html/info/da685c0bac">[da685c0bac]</a>.</li>
      <li>Fix the (unsupported) legacy CryptoAPI based codec so that it no longer prevents page size changes.</li>
    </ul>

    # NOTE: This job of this procedure is to return the list of "known"
    #       versions of Mono supported by the test suite infrastructure.

  #       small lists because of its heavy use of recursion and complexity on
