 ## Minimum Requirements
 
-To run Xvirus SDK you need:
-
-- .NET 5 Runtime - [download](https://dotnet.microsoft.com/download/dotnet/thank-you/runtime-5.0.11-windows-x64-installer)
-- Visual C++ Redistributable 2019 - [download](https://aka.ms/vs/16/release/vc_redist.x64.exe)
+No minimum requirements needed!
 
 ## Changelog
 
-- Completely redone in .NET 5
-- Now supports Linux (CLI and C# bindings only)
-- Added XvirusAI scan engine (BETA)
-- Scan speed is up to 2x faster
-- Fixed memory usage spike when scanning large files
-- Removed file size limit for scanned files by default
-- The checkUpdate function can now check for SDK updates
-- Added 3 new settings "EnableAIScan", "MaxScanLength" and "DatabaseVersion"
+- Version **4.1**:
+
+  - Upgraded from .NET 5 to .NET 7
+  - C++ bindings now also support Linux
+  - Removed Minimum Requirements on C++ bindings and CLI
+  - Changed how exceptions are handled in C++ bindings

 ## Known Issues
 
 - XvirusAI engine is still in BETA. It is not recomended to use in production yet.
+- XvirusAI engine does not work in C++ bindings.
 - The checkUpdate function can now check for SDK updates but can't update it
 
 ## Get Started
 
 The "`example`" folder contains an example project on how to import and use Xvirus SDK in C++.
 
-This project shows you how to statically load Xvirus SDK using `xvneng.lib`, you can also dinamically load `xvneng.dll` like any other dll, [see](https://stackoverflow.com/questions/8696653/dynamically-load-a-function-from-a-dll).
+This project shows you how to dynamically load Xvirus SDK (`XvirusSDK.dll`) for both Windows and Linux and call a function. You can also read more [here](https://stackoverflow.com/questions/8696653/dynamically-load-a-function-from-a-dll).
 
 You can run it by building it, copying the files from the `bin` folder to the output folder of the build and then running `xvbdc.exe`.
 
 ## Avaiable Functions
 
-You can find the declaration of all functions and structs in the file `xvneng.h` located in the "headers" folder.

 - **load** - Loads Xvirus Scan Engine into memory, if set `force`=true it will reload the scan engine, even if it is already loaded.
 - **unload** - Unloads Xvirus Scan Engine from memory.

-If any of the functions fail it may return an [exception](https://www.cplusplus.com/doc/tutorial/exceptions/).
+If any of the functions fails the `success` property returns `false` and the `error` property contains the error message.
