The 1.1 and 1.0 series expose a similar feature set. Internally,
the 1.1 series has been refactored to plan for future feature
additions. A new configuration file format has been introduced,
and limitations have been lifted. And the code quality and quality
assurance has been improved.

Fixed PECL #59982 - Unusable extension with --enable-mysqlnd-ms-table-filter.

<p class="para">
The <span class="function"><a href="function.mysqlnd-ms-set-user-pick-server.html" class="function">mysqlnd_ms_set_user_pick_server()</a></span> function was removed, and
replaced in favor of a new <em>user</em> filter. You can no longer set a
callback function using <span class="function"><a href="function.mysqlnd-ms-set-user-pick-server.html" class="function">mysqlnd_ms_set_user_pick_server()</a></span> at
runtime, but instead have to configure it in the plugins configuration file. The <em>user</em>
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 possible to use static class methods, or class methods of
an object instance, as a callback. Doing so will cause the function
executing a statement handled by the plugin to emit an
<strong><code>E_RECOVERABLE_ERROR</code></strong> level error, which might look like:
"<em>(mysqlnd_ms) Specified callback (picker) is not a valid callback</em>."
Note: this may halt your application.
