According to Microchip, they claim Harmony v3 exists, they even have documentation on it, but I am unable to find any download links:
https://www.microchip.com/en-us/tools-resources/configure/mplab-harmonyThere's even a big button reading "Download/Install MPLAB Harmony v3" but it takes me to documentation and no download links.
I found the download link for Harmony v2 though, so is Harmony v3 really a thing, or is it just vaporware?
