Imagine all of them break, you fix the first, only to find out that the second breaks as well. so you fix that, only to find out that the third breaks too, and so on.

I very much empathize! It was basically this frustration that drove me to writing that `pytest-accept` plugin. If you'd like to do these as doctests, that is fine too — whatever you think is best.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,937336962

OT (edit): By the way, these incompatibilities happen when one side decides to change the API without considering that some users may actually use that interface (and looking at the pandas' ""deprecation"" list, I fear that this will only get worse). Nice from the `xarray` people to have a section about keeping backwards compatibility as much as possible in their contribution guidelines.

@Illviljan It is a good idea, however, I'd prefer if those changes were introduced as an *option* first, before changing the default behaviour.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,937336962

The changelog is in [`/doc/whats-new.rst`](https://github.com/pydata/xarray/blob/main/doc/whats-new.rst), and the `repr`s are documented in [`/doc/user-guide/data-structures.rst`](https://github.com/pydata/xarray/blob/main/doc/user-guide/data-structures.rst) (not sure if that has to be modified), but there might be other files / docstrings.

For tests we usually use `pytest.mark.parametrize`. This would require a new test function (`test_display_max_rows`?), where you could check the number of lines of the `repr`.","{""total_count"": 1, ""+1"": 1, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,937336962

Sure, but it will take a bit. Could you point me to right places for the docs? Just the filenames would do.

I would be in favour of waiting a little with this change to get a few more opinions.
This change will ignore `display_max_rows` for everything except `dataset.__repr__`,
which may not be what some people might expect or hope.
Any ideas how to get more people to weigh in?

Edit: I would also like to separate the tests, to make it easier to follow if something breaks, but the setup for the test dataset would be the same. Any preferences or best practices for the code layout in such a case without duplicating too much of the code? However, that can probably wait for another PR.","{""total_count"": 1, ""+1"": 1, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,937336962

Could we add a short note on the change to the whatsnew? To the extent the existing docs on the repr are now out of date, could we update those too?
