I disagree, a version from 2016 is not very old. I have a lot of documents using a ConText setup which works with this version
of luatex and context.

Last week I tried to use the latest beta with my documents and the beta was unable to run my documents. 
As it seems it is not backward compatible and I have no time at the moment to debug or test.

So no, I cannot update at the moment.

@Wolfgang,

Ran your example (unsure about all these \definefontfamily commands), but
does not work, a lot of errors

This is LuaTeX, Version beta-0.89.4 (TeX Live 2016/dev)
 ConTeXt  ver: 2016.03.13 23:40 MKIV beta  fmt: 2016.3.23  int:

You are using a very old version of luatex and context. You need to update your distribution or install context standalone, which can be installed in parallel with texlive.
