Prior to today’s patch you could slide down the right hand side of the puzzle entrance (sharkmaw) and be stopped by a stalagmite half way down, without taking any damage.
If you try this now, unless you are traited for reduction to falling damage, your character will almost certainly die. I tried this with 3 characters, all level 80.
Since there was no mention of a jumping puzzle change in the patch notes so I’m assuming this new behavior is unintentional and is a bug.
The remainder of the puzzle appears to play as it did prepatch.
