We’ve just release version 4.0.0-beta.20 of configlet. There is one key change in this release, and that is that the configlet generate action now behaves similar to other commands in that it is non-destructive by default. Previously, running configlet generate would immediately regenerate the introduction files, but you’ll now have to pass --update (and possibly --yes if you want to update non-interactively) to have it re-generate the introduction files on the filesystem.
It would be really great if someone could test out the new release. This is the last thing blocking us from dropping the -beta moniker of releases :)
