It's impossible to say if there is an update available or not because the official website is displaying a Please come back later message. The developers might be in the business, but until their official website comes online, it's hard to say if it does support Windows 10 or not.
I've also tried to use the info on other websites as well and they all redirected to the same Summation link that is not working. You will actually have to come back later to the website to see if they will return or not.
