It would make for very interesting challenge maps.. mazes where you only had so long to escape before monsters find you, randomly releasing mobs somewhere on map to have them hunt you down, ect..
I just made a 5x7 hollow 2 story structure. Inside the structure I have a sticky piston set to push a block out to make a path so the zombie's can get to me. I set 3 repeaters on full delay before the piston and placed a pressure plate on the outside of the structure and use redstone to snake around the inside to the repeaters. The zombie's path to the pressure plate and jump on it then they are able to get up to me.
WOW big find GloomyGus,.. if a monster is unable to find its way to you, then it will search out the nearest pressure plate attached to any object and jump up and down on it! I just tried this in a 10X10 pen with 6 pressure plates, only one was attached to anything (dispenser) and it will not stop jumping on it! You can use this to make compact redstone timers that never fail (among other things).
*edit they will go for just about any pressure plate, attached or not, but they seem to prefer ones that are attached to something
*edit edit - They go for the pressure plate closest to you in their pathfinding AI.
I can't really do videos, my internet is too slow. But if somebody could make me one to post on front page that would be great. Just build a 10x10 pen of glass, with a steel door, and a pressure plate inside (attached to door), put a wolf in there, aggro wolf, then fly out and show it getting through the door and upload it for me that would be awesome.
* edit - zombie works better at getting through doors
I don't think the zombie's know to look for the pressure plate so much as the code makes them recognize it as a full block and the pathing thinks it is a valid path to me since it is considered 1 block high. I also believe they recognize the water blocks as solid blocks also and not a fluid block. I don't know if the code differentiates the two.
You're right, that makes a lot more sense, it is trying to climb the pressure plate.. still that can be dangerous for some people, because it still activates doors under the right conditions.
Mhm, I'm really impressed with the dramatic change. Unfortunately it comes with some minor bugs, so be sure to report them to Jonk: https://twitter.com/#!/jonkagstrom. I've got a showing a few quirks about their AI, namely their behavior in water. If Jonk doesn't fix that, then water could be used defensively against mobs in some manner (not that it couldn't before, but it seems to utterly wreck their new pathfinding).
I think in a recent snapshot their pathfinding was changed to make them sink in water, so it's understandable it messes up their AI to a degree. But I think it's a welcome addition, as now it's going to hard enough to avoid a zombie on land, let alone in water. (If I'm wrong about the me sinking in water, let me know). It would be good to have some relief by dipping into some water.

"@BlameTC No the Zombies sinking is a bug, will take a look first thing on Monday. Not sure about spiders. Thanks for your good feedback!"
EDIT:
Currently testing the quirks of water and the new ai
Just giving a heads up that zombies seem to be quite buggy when it comes to water and chasing you. It seems they treat water (or, at least, the source blocks) as something they can hop on top of to reach you. But even so, they really like to derp around in water. From my experiments at least.

They do not sink (at least they have not for me)
In the video you are referencing, the monster instead tries to jump up on one block high walls out of the water because it is showing it as the closest path. If the walls were all 2 blocks or higher, then it would have found its way around. (this is obviously a small and easily fixable bug) Other than this, water has NO effect on their pathfinding.
I added some water pools in my maze to test it out, they still won.

Also zombies do NOT push buttons and flip levers.. thank god.

The whole "zombies sinking" was a BUG, not a feature. Unfortunately, many, many folk spread the word as it being a feature without reading up on Jonk's twitter: https://twitter.com/#!/jonkagstrom/status/155396417706405889
