Thanks, I like the revised development history as the organisation into sections and the exposition conveys the various development efforts and how they merged. By the way, does McCLIM have a file selector?
As for the Getting Started chapter, I'd like to take some time to read it in more depth. The first impression is that the old version feels like a tutorial and the new one is like a reference.
I don't mind the old version which quickly goes to the point, describes a complete working example program, and iterates by adding functionality and describing the additional features. The descriptions and the working code offer a concrete understanding of the basics of CLIM as well as the main concepts and terms.
The new version feels more abstract as it starts from a long, possibly overwhelming (for a newcomer) list of terms and presents program fragments that, despite the screenshots, may not give a complete idea of what to expect from the examples.
