We are currently working on a MySLQi extensions that creates duplicates the existing DW Server behaviors for Recordsets an basic insert / update / delete behaviors that uses MySQLi.
after that project is complete we will be working on upgrades to our products to move from using the deprecated MySQL library to using the MySQLi library.
Most hosts will have an option to allow you to continue using previous PHP versions to support older code instead of forcing you to use the newest version
