Yes. I see that contracts promise only a non-empty list, so I'll fix that. > I see the mod-pre-submodules and mod-post-submodules fields in the mod > structure.

If you have a module name resolver or `load/use-compiled' handler, the protocol for those changed slightly, too. > Aside: it's times like these where I wish there was an extensive > Racket summary document [...] > > In contrast, the document I'd like to see should be a guide that helps > me migrate code.

I see that it's missing the change to resolved module paths, though, which is a serious omission that I'll fix. You can get to the release notes from the documentation page by following the "Release Notes" link on the left of the page, and then the "Racket core" link. The change log is not the more extensive prose description that you'd prefer, though. At best, it's a list of alerts for updated documentation that you should check. I would like to do better, but I can't promise any more in the near future. _________________________ Racket Developers list: http://lists.racket-lang.org/dev
