PHP 7.3

Permalink
I have concrete 5.6.3.4 running with PHP 7.3 on my local WAMP server.
Initially I had some PHP Warnings in the concrete\core\models\custom_style.php file which were easily fixed by changing "continue" to "continue 2" on lines 75, 82 and 93.
Has anyone else tried PHP 7.3 and have you found any problems?
I have checked my PHP logs and after the initial warnings were cleared I am not seeing any errors..
