Since the launch of UE4, we have been working as quickly as possible to resolve important issues as they have been reported to us. Once a fix has been made, we try to respond directly to the affected users by providing a QFE (“Quick Fix Engineering” – quick focused fixes) which we have been providing on the AnswerHub and right here on the forums.
Once we have accumulated a number of QFEs, we bundle these into a Hotfix, which is a public patch that is auto-downloaded for all.
We have just released our first Hotfix that updates the engine to version 4.0.2!
The issues addressed in this hotfix include:
[Windows] Fixed DirectX 11 crash when launching on older GPUs
[Windows] Fixed being unable to compile Android projects when launching from the editor
[Windows] Fixed crash on startup for some AMD CPUs
[Windows] Fixed broken shell extensions when running RegisterShellCommands.bat in GitHub builds using “Run as Administrator”
[Windows] Added support files required for Subversion support (preview release)
[Windows] Fixed issue where engine could fail to compile with multiple versions of Visual Studio installed
[Mac] Fixed crash on startup caused by certain USB peripherals plugged in
[Mac] Fixed logs being cut off after crash
[Mac] Fixed crash on startup caused by non-standard maximum number of open files
[Mac] Noticeably improved performance on non-Intel GPUs
[Mac] Fixed crash on startup running ShooterGame as a standalone game
This hotfix will be automatically applied when you choose Update from the Launcher.
NOTE: If you are using any existing QFE or hotfix Preview, please be sure to remove the command lines for them.
NOTE 2: We are aware that this hotfix is larger than expected (4GB), we apologize for any inconvenience and will work to address this for future updates.
NOTE 3: For source code users, 4.0.2 is also now live on GitHub: https://github.com/EpicGames/UnrealEngine/releases/tag/4.0.2-release (be sure to be logged into your GitHub account)
We appreciate your patience and value your feedback while we continue to resolve incoming issues. While the QFEs and Hotfixes are intended to improve stability and remove blockers, we love hearing what you have to say about the engine and tools and what we can do to make things easier or improve your workflow for creating something Unreal.
Please feel free to post any comments or suggestions on the forums HERE as we closely monitor them and value your feedback.
