## Other changes in the notes

Short summaries of the rest of the notes, by area. Bug fixes are grouped and not every one is listed. The official notes have the complete text.

### Global

- Fixed several stability and crash issues across all modes.
- Fixed Military Camos and Apex Attachments appearing locked again after prestiging a weapon, several inaccurate camo unlock requirements, and a DMZ Challenge that listed Longshot kills instead of Headshot kills.
- Added weapon level icons to Melee and Launcher weapons. Updated the Events Panel.

### Weapons

- Infinity Ward says it is looking closely at weapon performance, that it has bespoke weapon tuning in Multiplayer and DMZ, and that it was already looking at potential weapon tuning for the following week.

### Apex Attachments

- The Beta included a few early seasonal event Apex and weapon attachments. They are not in the launch build, and Infinity Ward says they will return soon.

### Multiplayer

- Parties of up to 4 players can queue together in Free-for-All. Fixed the Portable Radar Field Upgrade not working in Free-for-All and invisible collisions near the Barracks on Summit.

### DMZ

- Gas Masks and Parachutes had incorrect usage counts. Disposable Parachutes now have three uses, and Gas Masks, Durable Gas Masks included, no longer break immediately on entering radiation zones.
- Players can steal back UAV Towers from enemy control. Fixed Bounty tracking, Lieutenant Hunt progress showing for other squads, and the Numb the Pain and Numb the Pain Pro Trait descriptions.

### Known issues

- The notes list enemy AI cars in DMZ moving without drivers or becoming stuck, with prospective fixes already released.

## What this update does not say

- The notes print no units for damage ranges, damage values and damage multipliers.
- Values the notes do not list are unknown here. A weapon missing from the tables was not listed as changed.
- Where a row has no before or no after number, the notes print none and no percent is calculated.
