The following table shows the ESP-IDF versions supported by ESP-ADF at the current time. The label 
means supported, and the label 
means not supported.
The ESP-IDF master branch is marked as not supported because the major feature changes it has introduced may cause conflicts with ESP-ADF. Yet, the ADF examples not affected by those feature changes can still run correctly on the IDF master branch.
End of Life IDF branches are removed. See IDF Supported Periods for details.
