Dear dotan goldberg, Hope you are doing great, The KSDK 2.0 is no longer available in our webpage please check the 2.2 version for the part number you want in the folder of the SDK go to the docs and check the release notes file, here you will find the changes from one version to another sometimes there are versions that do not change everything just some minor bugs, please check maybe the things you are going to be using did not suffered a major change or have not changed at all.
If you have more questions please let me know.
