Hello Felix,

Nice to hear that you find the work interesting. Yes, currently the latest
SD Erlang version is based on 17.4.

The good news is that we've got some money for a 9 months work (starting
from October 2016, actually) to clean up SD Erlang related modules (e.g. do
comprehensive testing, separate currently existing in OTP and SD Erlang
specific functionality, conform with Erlang OTP requirements). In other
words, move from academic to industrial standards. So, SD Erlang will be
moved to the latest version very soon :).

Input, advice on how to better approach the task, and friendly criticism is
very welcome :).

Best wishes,
