There was an update to the Test Server yesterday with a whole bunch of great additions and fixes, you can read the patch notes but we're going to highlight some of them here.
The first notable change was the "fix" to prevent objects being placed on top of dropped weapons, while many were using this to get around some annoying placement bugs like not being able to place a Workbench inside of lower level Shelters, others were using the bug for other means and creating towers of objects and stairs to hop into bases.
Next is that Punji Sticks will now correctly damage all zombies that walk over them and the Fire Axe has been fixed so that it can once again harvest wildlife and other corpses.
In terms of additions they have added new name male zombie model and also added zombie encounter music, so when you're in the presence of a bunch of zombies the music will change to create the mood, this can be turned down or off in the settings menu.
Probably my favourite addition to the game in months is the new "Build Bar", from here you will be able to see how many of each structure you have and quickly select what you wish to place and even place them consecutively without having to go into your inventory and select the next one manually. You can see a screenshot of the Build Bar below. Some data for the Repair Box was also added to the game files but I don't believe this is enabled yet.
Additionally there was data for a new crate and new items added in preparation for the H1Z1 Showdown event and the new Green Dawn BR game mode. Below is what we speculate to be the contents of the new crate based off of the data in the game files. As always this data may not be complete yet and is subject to change before going to live.
Also added during this update are the following items but we do not yet know for certain where these fit in, the description for the Gold AR reads "Congratulations on getting into the top 10 of the Showdown!" and the Showdown Shirt has a duplicate name of one above.
