Project Zomboid small update!

First off, http://projectzomboid.com/blog/index.php/2011/09/zomboid-0-1-5c-released/
Edit- New post on another fix, http://projectzomboid.com/blog/index.php/2011/09/project-zomboid-0-1-5d-released/

It seems the team is actually pretty hard at work, and they have a changelog of what's been done this small update.

Optimizations

A lot of fps issues appeared with the last few updates, so this is nice

Less rain.

It rained too often in the update. Pretty much more than half the time it was raining. This is also nice.

Various bug fixes.

They didn't seem to specify anything about this, but hopefully I no longer have zombies spawning behind staircases.

NPC tweaks 

They are attempting to make npcs less "hostile" towards you, and tried to make what they do more varied. Not sure what else an NPC is going to do, but we'll have to see what they have in plan down the line.

Multi-stage barricades
I haven't really had enough time or supplies in a game to create "real" barricades instead of just barricading the doors and windows. It sounds interesting though.

Increased sound muffle effect of being in/out buildings or different rooms

Some more realism is always nice. Being immersed is a great thing about this game.

Slowed down horde movement.

I found that I died a lot faster than I used to in the demo since the update, I actually like this. Some people may not.

They then leave a comment at the end
"teehee I love my spiked baseball bat, SQUISH, SQUSH, hehehe SQUISH, SNAP oh…"

If I had to guess, this is hinting to Item Durability.

All in all, a nice quick update with a few additions and some nice fixes and tweaks. They stated they are working on implementing saving in the background while releasing these small updates and fixes. So hopefully new areas and save games aren't too far off.

Edit- It seems they have another update that just came up that fixes a bug where you would infi-sleep. Obviously a game breaker. They also changed some perks and how uncooked food works. All in all, another nice quick patch.
