"deprecated constructor" error of AJAX Register on PHP 7.0.4

Today I made a test: upgrade my Joomla core to Joomla 3.5.0 RC, and upgrade my PHP to 7.0.4, then I got following error at frontend page :

Deprecated: Methods with the same name as their class will not be constructors in a future version of PHP; plgSystemAJAXRegister has a deprecated constructor in /public_html/plugins/system/ajaxregister/ajaxregister.php on line 23

Does this mean than Ajax Register does not support PHP 7.0 at present?

Please update this extension to support Joomla 3.5 and PHP 7 .

Thank you.

It's not error, just a deprecated message. Turn off displaying deprecated notices.

It has been removed from the plugin now so you can upgrade and test.
