The changelog for the upcoming v2.00.03 have been updated.
This patch is only for the paid version, but will also be incorporated into the upcoming paid DLC, The Lyrius Conflict, which is exclusively for the Steam version.
What we are going to do is, since we can't flag a DLC as Early Access, as advised by Valve, we are going to enable the store page with a notice that it is work-in-progress. Just like Early Access.
Doing it this way, if you have the free Steam version, you can just buy the DLC and get immediate access to on-going releases to the game which include bug fixes, tweaks, new features (e.g. official Windows 10 support), as well as the DLC content (wait for the page to go live to see what's in it).
For more info about the plan for the DLC, please see this forum discussion.
