CAST() no longer working with OOO 330m16

Just found that queries who worked for years are halted now (OOO 330m16) 
using Cast("timestampvalue" as date)
CAST("timestampvalue" as date) use to run in direct SQL mode
I think that CAST as date is no longer "loved" and by mySQL they 
recommand DATE("timestampvalue")  i have some queries around with CAST , 
do not know if there are more ? andis it whort a issue ?
