Sadly anything listed as legacy is not supported anymore...
But you can still download and use them on supported distros. (Ubuntu 16.04 LTS, Mint 18 and older.)
We had to make a lot of cuts for 2017 to refocus our efforts and time. Sorry if your favorite theme was on this list.
Please do not contact us reporting issues or things not working for the legacy themes listed.
It's been a hard break up and we are simply done with them now. Thats it. Unless you wish to sponsor further development.
