There's no way, AFAIK, to diff the files each version will install on your system. However, there are at least 3 ways to get at the changelog:
1) The full changelog is at /usr/portage/<package-category>/<package-name>/ChangeLog
2) emerge -l <package-name> will show the changes between the version you have and the version you want to install.
3) etcat changes <package-name> will do the same as (2) but in color. (etcat is in app-portage/gentoolkit)


2 and 3 usually work, but it's possible to confuse them, so 1 is the most reliable.

hi folks,


anyhow, i write primarily not to praise gentoo, but to ask a question. i'm still marvelling at the shiny emerge sync ; emerge -uv world process that keeps me at the front edge of things, so i do it almost daily. i'm wondering if there's an easy way to see what's changed in a package between the last release and the current release? (for instance, my window manager ratpoison wants to be upgraded from the installed 1.2.2 to 1.2.2-r1. this sounds like a tiny change. i'd like to see if it's worth listening to my disk grind for 20 minutes.)

it seems likely that i can grab the newer ebuild and
diff it against whatever's still cached from the old build.
i'd welcome instructions in that direction if there's no
better tool.  seems like emerge or qpkg probably has some
way to show me the changelog, but i can't seem to find it
in the docs.

thanks in advance for any advice.
