OpenCV 3.0 not longer recognises 'CvSVM'

I recently updated to OpenCV 3.0, and my old code which trained an SVM has stopped working. Now writing this

CvSVM SVM; // or this
cv::CvSVM SVM;

gives me the following error:

error: unknown type name 'CvSVM'

Does anyone know whether they've changed the names in OpenCV 3.0 or if it's a bug in the new release?

It's cv::ml::SVM

and you will need to use it like this:

Ptr<ml::SVM> svm = ml::SVM::create();
svm->setC(10);
