I've always considered two different ways to deliver changes and
sources, and never got enough experience with it to know which I
preferred.

The first approach was for the changes file to contain the changes
that occurred from the prior release to arrive at the current release.
The second way was that the changes file would start empty at the
beginning of the release, and then any changes the user put in are in
that file, which seems to makes sense.

Since we can keep all prior history in sources now, seems like the
second approach is best.

4.6 deserves a new sources file, and #prepareNewRelease is where we
should do whatever we're gonna do, every release.  #condenseSources
(historically) seems like the right thing to do for every release, so
how about that?

But can condenseSources be run non-interactively?
