Dev kit update, when?

Do not know if this is the right place to ask but here goes…

When are you going to update the dev kit it has not been updated since v 268.3, even GitHub has the old version so we cannot update through that either, last GitHub update is dated May 10 2017, I have loads of users of my mods asking when I am going to update to the new game specs and will this work with Abberation I have to say "sorry cannot update as we are styill using OLD OUTDATED software.

Can you take time out to update this please as modders are being forgotten here, and in my eyes that is a gross error by Wildcard.
