The answer, I'm afraid, is that there are no immediate plans for a second edition in English. For now, it is available in Serbian, and should soon be available in Russian. That's it.
The main differences between the first and second editions are that
- errata (noted here) have been fixed, and many of the addenda (noted here and in some early entries to this blog) have been added in to the main text.
- the sections dealing with Russia have been entirely rewritten. Chapter 12 has become two chapters, and sections of chapter 13 are different. Some of the extra material concerned will be made available in English in stand-alone scholarly articles; when this happens, I'll announce it here.
