> ⚠️ **MATLAB support changed to use .NET**  
> ⚠️ Built-in MATLAB integration has been replaced by .NET, as Mathsworks support the use of .NET directly in ([MATLAB](https://uk.mathworks.com/help/matlab/using-net-libraries-in-matlab.html)).   
> ⚠️ To make use of DataStream SDK 1.10 and later, update legacy MATLAB scripts to .NET.   
> ⚠️ To continue using native MATLAB integration, refer to support in DataStream SDK 1.9.
