Can't go to bottom or depth of water since new "update"

Since you made an update which almost brought/bring nothing in survival mod, you can't go in deep in water because flowing take a lot and a lot of time !

So you can't kill a squid for taking his ink sac because it go to ground of ocean, can't acces anymore to a door locate under 10 blocks of water because it will cost heart and many others way.

When do you update game to aquatic ? Because actually have done a update for wich I only have a new graphic for Sugar cane and nothing else new exept bugs because i'm not playing on creative !
