The answer is yes and no 🙁
There are lots of changes in the code on Github. But to get these changes you would need to build from source, which is not hard, but still requires some work. And you would still need a current copy of stdlib which is not on Github.
I have not made a pre-built release since 2013. That is just my laziness. I am busy, but it does not take much time. I should put out releases more often.
