Hello,

is ESP-IDF 4.1 (not 4.0.1) supported? If I try to check it out and build my project, I get:

The weird thing is that though I selected v4.1 in VisualGDB Project properties, it still seems to use the 4.0 checkout. I could try to start anew and re-import the project, but only if I know that 4.1 is supported indeed.

Thanks
