I'm really excited about this, Deathly and I have wind effect on bullets working in our test environments at the moment with mutiplayer optimization that will in theory have zero noticeable performance impact. This coupled with Rekt's dynamic weather are making this very fun and interesting.
 
The current implementation allows for the following:
 
1) Dynamic wind effects on all projectiles.
 
 
2) The ability to edit the effect wind has on each bullet e.g. I can make more aerodynamic bullets that are less impacted by the wind.
 
 
3) Wind prediction possible by environmental cues. Trees swaying, grass bending, clouds moving across the sky, all of these are synced with the *actual* direction of the wind allowing to you to observe your environment to properly compensate.  
 
 
4) Negligible impact on short range combat,as it should be. The effects will become noticeable around 200m and beyond. For example, shooting directly across a moderately stiff wind at an open window in a house 250m away without compensation caused my bullet to miss the center of the window by approximately 3.5 mils.
 
Bullets fired down wind (zero value wind) will fly true to the target and will maintain their point blank range longer. Bullets fired against the wind will then obviously be slowed more quickly and knocked down.

From next dev server update there will be care pkg drops from a new type of random helicrash. Keep an eye out
After so many care pkgs have been dropped it will also crash somewhere and spawn even more loot.
These care pkgs have a unique loot table with never seen before weapons / items / backpacks / medical supplies.
 
The Chinook will fly to random drop points and release a slinged care package which a parachute will deploy from the care package until it hits the ground. In the update after this one smoke will also be released from the care pkg so you can spot them. Also this requires a bugfix for smoke grenades not deploying smoke correctly, which will be in soon.
 
There was also details discussed of these care packages on the live stream we did this morning.
Also another note the chinook will fly at a slightly lower alt and speed, which will give you the ability to shoot at the ropes holding the cargo which can cause an early drop.

Fixed: Missing gear and other issues with dead bodies.  

Mechanics might need some explaining so i thought id post the information here..
 
Taking adrenaline causes the following:
 
- Temporary removal of all arm/leg damage effects (60 seconds)
- Temporary removal of low blood effects (60 seconds)
- 15% movement speed increase (if possible) (60 seconds)  << not sure if implemented  
- 50% damage decrease (60 seconds)
- Upon timer expiration, set fatigue to 1.0 for adrenaline "crash"
- 10% chance of death if taken with 90% or greater health
- 100% chance of death if taken while still under the effects of previous adrenaline

Here are the details for this recent change:
 
Players must now select either "Examine" or "Loot" when interacting with a dead body. Detailed death information will be implemented soon for the "Examine" selection. When you select "Loot", an animation will play and the dead body will be respectfully buried if you are a Ranger/Nomad/Survivalist, or stripped of all flesh and organs if you are a Hunter/Outlaw (possible additional raw meat items for this coming soon?)
 
Here are the things this change was designed to address:
1) A fix for the "stop selecting the hatchet, I want to access the body" problems that occur due to the fact that it is hardcoded in Arma to have an armed player drop their primary weapon upon death. Bonus: It prevents those dropped weapons from despawning too quickly.
 
2) A once-and-for-all fix for dead body item duping, a long standing BI issue that has been supposedly fixed by them multiple times.  
 
3) It halves the number of objects created by a dead body which helps server performance. Bonus: It allows us to disable simulation on unlooted bodies which also helps server performance.
 
4) It provides an easy vector to flag someone as a traitor for looting a particular type of body since an action must be selected now.
 
5) It makes identifying looted/unlooted bodies easier which makes it a little more exciting I think i.e. seeing a corpse on the ground means that no one has gotten to it yet. Also can be used to help identify possible traps/sniper kill zones.  
 
 
Here are the known issues:
1) Navigation in buildings with too many "looted" bodies. We will be researching a fix for this.  
2) Vests and Belts turning into a generic item (FIXED IN NEXT PATCH).
 
Please post any other issues you have encountered in this thread.
