This is the third prerelease of version 0.4.0 of UndertaleModTool.
Before the full release of 0.4.0, we aim to finish implementing dark mode (see the dark-mode branch) as well as solidify the profile system. But for now, we thought it would be a good idea to make the current feature set available for general usage.
It's important to note that the .NET version that UndertaleModTool uses has been upgraded to .NET 5.0. This means you may need to download the .NET 5.0 Desktop Runtime, at https://dotnet.microsoft.com/download/dotnet/5.0/runtime. Make sure this is the same architecture as the version of the tool you download; for instance, if you choose x86 for this tool, make sure you download the x86 runtime. If this does not work, please use the "NetBundled" versions of the tools, which do not require installing the net runtime.
Also, since this is a pre-release, it may have some instability. Please report those issues, should you encounter any.
