I’m not totally sure but I think there has not been a new update release since v14 according to info on Download page maybe another version is coming but there is little infomation out there as to If and when.
I believe @GWAK already opened a ticket/feature request here. If they do not get back to you, and if you need an update, I suggest you describe the issue you are having as it will put more weight in your request. If I were you, I would engage them in twitter.
