We've set the release date for patch 1.5 for Thursday, November 17th.
We already know that saves from previous versions of Resurrection won't be compatible with version 1.5. On the plus side, with the patch you'll gain a large number of bug fixes, and various other small improvements. If you want to know right now what's new in patch 1.5, you can see the current changelog for version 1.5 (beware though, it contains SPOILERS!) right here. It isn't a final list, a few changes will yet be added up to release.
