 <h2><b><a name="introduction"></a>Introduction</b></h2>
 <p>Please note that the following description relates to a depreciated interface as it was used by default up to Boost V1.34.x. For the new interface please refer to <a href="class_reference_ctxpolicy.html">The Context Policy</a>. You can still force to use this older interface by defining the <tt>BOOST_WAVE_USE_DEPRECIATED_PREPROCESSING_HOOKS</tt> preprocessing constant as outlined in the <a href="compiletime_config.html">Compile 
-Time Configuration</a> section. By default the new interface is used starting Boost V1.35.0, while the older one is used by default otherwise. </p>
+Time Configuration</a> section. By default the new interface is used starting Boost V1.35.0, while the older one is used by default otherwise. The old interface will be removed entirely with Boost 1.76.</p>
 <p>The context policy is used to provide callback hooks, which are called from inside the library into the user code, whenever</p>

   <li>a preprocessor directive has been recognized, </li>
