And that is the problem, many mods depend on specific nightly and when someone upgrade to latest can't go back because old one aren't publicly available.
We have already couple people and mods affect by this.
My point is that current 1.0 is obsolete for mod authors, many great features was added after it. My suggestion is to create alternative that will be protected form breaking changes.
Version of this new milestone is irrelevant. It could be 2.0, 1.1 or 1.0.1, only important is content of it.
At the same time, the more milestone versions get released, the bigger the confusion. And preparing a milestone takes time that could be better used to further development.
If you release a new milestone at this point then it will break a lot of mods, plus it is likely that those mods will need to be updated, again, if something is changed on further nightlies and when TFTD gets finished. So for some mods you'll need 1.0, others 1.1, and then there will still be mods that only work with the latest nightly.

1.0 is completely fine for me regarding the Terrain Pack and for a lot of other mods. I've made a deliberate decision of keeping the updates to my mods compliant with 1.0 due to a number of reasons:
* Most players won't care about downloading a nightly just to try a new feature.
* It can take a lot of time to be constantly updating a mod that requires a nightly.
* And the new nightly features required by mods have a minimal impact in the overall game, despite what we mod authors would like to believe
So, if you choose to use nightly features in your mods, keep in mind that you'll have to deal with the above points.
