UPDATE: DICE has released a new patch for the Xbox 360 version of Battlefield 4.
You'll need to manually download the multiplayer update 3 from Xbox Live Marketplace, DICE warned. You won't be automatically prompted to do so.
The patch focuses on improving game stability and preventing crashes. "Accumulated, these fixes should help increase stability overall in the game," DICE said.

ORIGINAL STORY: DICE has issued new updates to the PlayStation 4 and PlayStation 3 versions of Battlefield 4 as it continues to work towards fixing the game.
A small patch was applied to the PlayStation 4 version yesterday that was pushed live as quickly as possible to deal with the "one-hit kill" bug, fix a crash issue and enable audio in PS4 video captures. A larger patch focusing on game stability is in the works.
The one-hit kill bug meant damage from a single bullet sometimes was applied multiple times and players were seeing normal rifles sometimes dealing one-shot kills.
"We are seeing reports from people that this is still present, with descriptions such as 'I came around the edge of a building and died instantly'," DICE explained on Battlelog.
"It is important to understand that this is not the one-hit kill bug, that is another issue that we are working on addressing. For this, it is important to understand how some of the interpretations made by the game happen so that you can understand the difference.
"We saw an issue where a bullet travelling towards an opponent would cause damage in one frame, and then again in the next frame. Therefore bullets would cause 2x damage if they hit the target between these two frames. This issue has been addressed.
"The issue of dying before you saw who shot you is a different beast. We use a term called interpolation in reference to where you are in the game world. There are instances where the death camera is initiated before the correct internet packets have arrived to be interpolated by your camera. This gives the impression that you were killed by 'one shot' as someone came around the corner of a building. We have identified this issue and will address it in upcoming updates."
Meanwhile, a larger patch has been applied to the PlayStation 3 version, addressing stability issues and, of course, the one-hit kill bug.
The patch also improves hit sync. "We previously removed interpolation of damage events (like you taking damage from someone shooting at you) to make them feel more responsive, but that made the damage sync suboptimal," DICE said.
"We are committed to tweaking the sync so that it will stay more true to what you are actually seeing. The first step towards this is taken in this patch, so you should see some improvement on this now. We will continue to work on improving hit sync in the game.
"This change is already live on PS3, PC, and PS4, and will go live on Xbox One and X360 in upcoming patches."
Earlier this week DICE put all of Battlefield 4's expansions and "future projects" on hold to focus on the mess that is Battlefield 4's launch. The decision followed the release of the China Rising expansion, which brought with it a whole new host of problems.
