Ahoy,
I added a file called NEWS. Here we can record interesting user-visible changes to SLIME in a digest format so that users can learn about new features.
I'm thinking this is worthwhile because it'd take a fair bit of work to fully track the mailing list and ChangeLog these days.
The idea is that each time we release^Wmove the FAIRLY-STABLE tag we can send the current NEWS section to the list and start a new section in the file.
Cheers, Luke
