Hey!
The change to combined tuning was purely an optimization change. More efficient to load binary data than raw XML.
Answers:
1) XML will still work. The runtime supports loading of both formats. So tuning mods should not be affected by this change, unless the mods are broken due to other functional changes we have made.
2) Simdata.bt. Will work on that. Note that we bumped to version 0x101 back on the careers patch and it was a pretty minor change.
3) CAS Part .bt. Will work on that, not sure what we did there off the top of my head.
4) tdescs coming soon. I will also look into providing you the new combined tuning file in the old XML format.
Will get #4 to you as soon as I can. I had been meaning to get something out to you yesterday, but was a hectic day. Also, for the record we do consider modders when we make these kinds of changes but sometimes we have no choice but to make drastic changes. Appreciate your guys' patience.
