Diff files from upstream to local branch

[RoadRoller01]

its will be useful to just know which files got changed,
especially if there was a lot of small commit.

In the vanila git i could just run
git fetch
then
git diff master origin/master
or
git diff master origin/master --stat

The easiest way to do that is to select all commits of your branch as a range selection (using shift-downarrow). This will show you the combined diff of all the selected commits (and you can press enter if you want to see the individual changed files). It may be cumbersome to do when your branch is very long, but for reasonably-sized branches it works quite well, and I do this often.

Note that this is different from running git diff master origin/master in the case that your branch is not quite up to date with its upstream (i.e. if other people have pushed things to master in the meantime), because the diff command would also show you those other changes, which is likely not what you want; the above range select method doesn't have this problem. Obviously this is not an issue when you are working alone on your repo.

Finally, if you really want to do the equivalent of git diff master origin/master then you can do that by selecting master in the branches panel, pressing shift-W, and choosing Diff master@{u}. This will select origin/master as the "from" end of a diff, and diff that against whatever is selected, which is master in that case. Just don't forget to press Escape to get out of this mode when you're done, otherwise it can be very confusing if you move around and see diffs that don't make sense.

Yeah I forgot to say that I must run git fetch before using the command, in case you missed it I edit my comment.

Also special thanks to your fast and self-explanatory reply

There's an option to view divergence from upstream:

Be in the 3rd pane, local branches and type u for upstream, and you get this menu

But the issue is, you don't get an overall diff, but a per-commit diff on all diverging commits..

EDIT: Figured it out!
Use the W menu while in upstream divergence view.. and select Enter ref to diff and select the upstream branch

Then you get a view of the diff in pane 4:
