There was a package called paradox which had more features
on the package UI.  It included a command
paradox-commit-list that opened a buffer showing one line
per commit with the commit message and a button that was a
link to the commits diff.  It bolded the commits since the
current installed version to make it easy to see the
changes.  It only worked on github hosted packages.  It
would be great to have this functionality in package.el
particularly if it worked on non-github hosted packages.

I think your idea of adding an option to show the change log is good. It
would be nice to have a `package-upgrade-review' option which could be
set to `nil', `news' or to `diff'.

But I want to emphasize that your suggestion misses the security aspect.
Security is the main reason why I made the proposal. The goal is to make
it easier and more convenient for users (yes, users who are "technical"
and familiar with Elisp) to assess the safety of package upgrades and
possibly report any irregularities to the package archive maintainers.
While packages are commonly reviewed at the time of their inclusion in
package archives, this is often not the case later on.

My proposal does not address or affect the first time installation of a
package. At this time it doesn't make sense to show a "diff" and the
user must first check the package closely anyway.

Daniel

describe-package (C-h p) works on all packages, but the news feature I
described wouldn't work as it uses a local file.  But that is not a
hard-constraint, we could serve news data as well.

I don't know how much sense it makes to present a diff when installing a
package.  News files are probably also not that interesting.  We could
provide a command like package-vc-checkout that just fetches the package
source and places it somewhere for the user to inspect.

Isn't it the case that describe-package works only on installed packages,
not prospectively installed packages? To help determine the value/risk of a
package install or update, I'd think it better to show this in advance.
Daniel's diff suggestion is similar but more technical.

Note that packages can distribute this information.  Currently, if a
tarball includes a "news" file, it will be displayed by
`describe-package.  IIRC no package archive generates these right now.
But if we implement a user option like that described above (or below?),
then we can add that as an option as well.

The main issue is that not all package maintainers ensure that there are
changelog/news sources that ELPA could use to provide this information.

I like this idea, too. I spend a reasonable amount of time trying to
understand what people have changed and if it will affect me negatively
(the defensive part) or positively (for new features, user options,
deprecations). Showing a source-code diff may be a bit technical for some
users, though. I wonder if there could be either a link to a changelog, or
a way to encourage a changelog convention so one could be displayed for
users prior to a decision to update a package.

That sounds like a good option to have!  I'll look into adding something
like this via a user option that adjusts how to confirm a package upgrade.

Note that package-vc has something similar with the
`package-vc-log-incoming' command.

This is a feature request for the security wishlist. When upgrading
package it would be good to show a diff between the new and old package
files. Such an option could help performing review casually as part of
the upgrade process and may improve the security of the package
archives. More eyes would look at new package versions. This would make
it harder to inject malicious code either via the source repository or
via attacks on the package archives.
