+    Users of the function <function>mysqlnd_ms_set_user_pick_server</function> need to
+    update their code. The function has been removed in favour of a
+    new <literal>user</literal> filter. You can no longer set a callback function
+    using <function>mysqlnd_ms_set_user_pick_server</function> at runtime but have to
+    configure it in the plugins configuration file. The <literal>user</literal>
+    filter will pass the same arguments to the callback as before.
+    Therefore, you can continue to use the same procedural function as a callback.callback
+    It is no longer possibe to use static class methods or class methods of
+    an object instance as a callback. Trying to do so, will make any function
+    executing a statement handled by the plugin
+    emit a <constant>E_RECOVERABLE_ERROR</constant> level error like
+    <literal>(mysqlnd_ms) Specified callback (picker) is not a valid callback</literal>.
+    Please, note that this may halt your application.
