Guess there are two new areas in 0.5.0.2. First, the A5 floor is now accessible, and features a long arena fight to waste what stuff you had left since the "zombie defense". Also A1 iirc (the one that is locked off with a fence) now has a vent. The area behind the vent has two stake traps from the Halloween event and a puzzle where you have to shoot a hanging zombie onto a button (DO NOT jump there yourself, or you will soft-lock!).
These are actually a "New Game Plus" thing, when you start a new game after having already finished the level before. It'll say "Welcome back" during the starting cinematic. They've been there since 0.5, but aren't available on your first playthrough.
So far I found a fun bug in 0.5.0.2 tho, where the pistol somehow was showing zero ammo (although I had some), and could not be selected (Jodi would hold an "air pistol" instead, did not try to shoot it and somewhat glitched out the weapon selection when switching from this "air pistol" to anything else). Thankfully, happened in a challenge map. Dropping and re-picking the weapon had no effect. I guess that is somehow related to picking a weapon while both the auto-switching is enabled and you are in already in a different switching animation.
I'm not quite sure what causes it either, but I've only had it in story mode and it happens sometimes when I reload my save. It was there before 0.5.0.2 but the update actually made it worse, as before you could just swap to another weapon and back to the pistol (it's always the pistol that breaks), and everything would start working again, except your pistol's magazine would have 1 ammo so you'd have to reload it. The other weird thing is that when you first get this bug, trying to interact with something can instead cause you to pick up a full pistol magazine. This gives you a net +1 pistol bullets! ...except in 0.5.0.2, swapping weapons no longer works so the only fix I've found is to reload again (your save, not the gun). The only good news is that there's no possibiliy of breaking the game long term, even if you save while bugged, reloading that save will still fix it.
In the Hangar, activating a revive point and then dying would probably fix it, but in other challenge modes I guess you're probably just screwed.
Found another 0.5.0.2 change. In B2 after falling down the stairwell, there were a couple wildcard ammo boxes like in the Shooting Range that would give you exactly 50 ammo for whatever weapon you have equipped (INCLUDING daggers and axes!). These have been replaced with pistol a handful of ammo boxes. (EDIT: And the one where you fight the predator has been replaced with a regenerating rifle ammo box.)
Also, though the change log mentioned turning the very first mirror you find into a full wardrobe, the "A5 Staff Dormitory" (actually A4, but it's called A5) also has a wardrobe!
By the way, unrelated, here's a Storage Box full of... everything. Even wooden boards, and code breakers that you can't even transfer to and from storage. Maybe in the future it will be possible!
If you want to have room to put things
into the storage box to get them out of your inventory without discarding and cluttering up the place (never discard a stack of 500 by the way, you will regret it), you can go to Jodi's Office and take some from the storage box there and then just leave the office, deleting them and making room in the storage box. Then you can keep a backup of your StorageBox.sav which you can use to reset your storage box to that state.
