My reasons for arguing were basically these:
- by having all of the information in one place, folks who are reading the
changelog also get the benefit of the NEWS stuff, which is often useful in
a changelog context as well
- (a selfish one) I wouldn't have to figure out how to appropriately display
both kinds of information in apt-listchanges
Something like this:
apt-listchanges (2.23) unstable; urgency=low
NEWS: This version now extracts news items and displays them to the user.
The new default is to display only these items. If you want the old
behaviour back, reconfigure apt-listchanges.
NEWS: It also has a higher version number than the previous release!

Seems natural and logical to me. The only disadvantage I see is that
multi-paragraph news items could get a little unruly, but IMO a well-written
news blurb is one paragraph long.

If we're going to have a separate file, this is about as easy as it gets,
and I think it's a sane approach.

I agree re: option 1; that would be a sane configuration default.
Option 2b works out to pretty much exactly the combined news/changelog
format that I had in mind. I don't like 2a very much because it spreads out
the information about a single package, such that I would have to navigate
around the output in order to correlate the news with the changelog.

If I am in the minority, I will not hold back the entire NEWS concept just
because of the file format issue, because I want to see this happen.

The current mechanism is designed to extract only one file, so the pipe
mechanism works out pretty well. You could have changed things to call
extract_changelog twice as well. I think, though, that if apt-listchanges
is to start extracting multiple files, I'd probably want to just extract
them to a temporary directory. That way, it doesn't have to make more
passes over the .deb, nor would I have to deal with getting them both in a
Of course, if the news items are in the changelog, this is a non-issue...
