Hooray! A new patch! That means new things to explore! Here are the change details from the offical blog

Optimizations - Hopefully a ton less lag.
Less rain.
Various bug fixes.
NPC tweaks – Less chance of hostile NPCS. A bit more varied behaviour. Still needs work but we’ll keep adding to it.
Multi-stage barricades
Increased sound muffle effect of being in/out buildings or different rooms
Slowed down horde movement.
teehee I love my spiked baseball bat, SQUISH, SQUSH, hehehe SQUISH, SNAP oh…

I’ll be doing a playthrough of this sometime soon. Probably tomorrow or the next day!
