更新v20190621：
正如我们在2019年5月宣布的beta版本中所述，最大的更新是从虚幻4.16跳到4.21。引擎跳转引入了全面的改进并涉及游戏的各个方面，因此虽然不可能记录每个更改和错误修复，但我们确实想要涵盖一些高级别的更改，特别是：
图形渲染和游戏逻辑代码中的性能改进
HDR模式现在可以正确渲染
PlayStation和Xbox上的图形都得到了极大的改进
对于Xbox用户，游戏现在将识别Xbox One X和Xbox One S控制台，并根据需要提供4K和HDR
当然，引擎本身有很多错误修复，因此曾经有过奇怪的一次性配置问题的玩家现在可能会发现这些问题得到解决。
除了上述修复，我们还有一些新功能：
结合了野兽和停电的新敌人
从故障发生在服务站的新入侵地图
Matchmaking现在可以搜索特定游戏模式中的任何地图（Campaign或Invasion）

Update v20190621:
As we stated in our May 2019 announcement for the beta build, the biggest update was to make the jump from Unreal 4.16 to 4.21. The engine jump introduces widespread improvements across the board and touches every aspect of the game, so while it抯 impossible to document every change and bug fix, we did want to cover some high-level changes, specifically:
Performance improvements in both graphical rendering and in the game logic code
HDR mode now renders correctly
The graphics on both PlayStation and Xbox are greatly improved
For Xbox users, the game will now identify Xbox One X and Xbox One S consoles and provide 4K and HDR as appropriate
Of course, there are many bug fixes in the engine itself, so players who used to have odd, one-off configuration issues may now find those issues resolved.
In addition to the above-mentioned fixes, we also have some new features:
A new enemy that combines a Beast and a Blackout
A new Invasion map that takes place at the Service Station from Breakdown
Matchmaking now allows searching for any map in a specific game mode (Campaign or Invasion)
Additional changes and fixes:
GENERAL:
Fixed the ability to Play Solo, with no network connection.
Significant improvements to AI pathfinding
Fixed AI collision problems with cars and trucks
Fixed menu cursor navigation when using a controller on PC
Fixed a problem in which the Gameplay Tips screen could disappear and also hide the main menu
Fixed barricades to no longer cast the shadow of a propane tank that is not there
Added in the ability to override the HDR settings for PCs where the HDR is detected but not represented correctly on the monitor (i.e., the game looks overly or under saturated)
- Please check the included KnownIssues.txt in the root folder of the install for more information
WEAPONS:
CVA: Fixed a small graphics problem with the scope when not in ADS mode
F4-NG: Fixed reload audio
Shard Grenade: Fixed a small graphics problem with the grenade model
CAMPAIGN MAPS:
Revelation: Fixed the Beast's ability to climb up scaffolding, over railings
R&D: Fixed a turret placement location in the final warehouse
The Diversion: Fixed an area where the Whiplash could drag players out of bounds
Into the Breach: Players should no longer be able to get stuck in the resistance crate
Into the Breach: Fixed AI navigation through building window
INVASION MAPS:
We changed the level 3 Health perk so that now it generates your health up to 35% (was 15%).
Nuclear Facility: Fixed areas where AI could get stuck
The Mines: Fixed the Beast's ability to climb to the upper back area
