Enough people are using xarray in production that breaking changes are made with serious caution (and deprecation cycles whenever feasible). The only major backwards-incompatible change planned is an overhaul of indexing to use labeled broadcasting and alignment: https://github.com/pydata/xarray/issues/974 There are a few other "nice to have" features for v1.0 but that's the only one that has the potential to change functionality in a way that we can't cleanly deprecate. > Is there significant overhead compared to plain ndarray? Xarray is implemented in Python (not C), so it does have significant overhead for every operation. Adding two arrays takes ~100 us, rather than <1 us in NumPy. So you don't want to use it in your inner loop. That said, the overhead is independent of the size of the array. So if you work with large arrays, it is negligible.
