Existing Sites using dataassist
You can use our MySQLi Server Behaviors for new sites using PHP 7. MySQL has been replaced by MySQLi (the "i" stands for improved). If you build sites with those they will continue to work for the foreseeable future on future versions of php.
Can you please clarify - What is the plan for sites built using dataassist? I plan to have my websites up and running long beyond the next decade. What are my options?
