Please see the [migration guide](https://python.arviz.org/en/stable/user_guide/migration_guide.html) if you are getting errors after upgrading ArviZ. Highlights of breaking changes: * InferenceData object no longer exists, we now use `xarray.DataTree`: https://python.arviz.org/en/stable/user_guide/migration_guide.html#datatree * Several plots have been renamed, including `plot_posterior` and `plot_trace`: https://python.arviz.org/en/stable/user_guide/migration_guide.html#plotting-function-inventory * Plotting functions now return `PlotCollection` objects: https://python.arviz.org/en/stable/user_guide/migration_guide.html#what-to-expect-from-the-new-plotting-functions * `waic` is no longer available as a function nor model comparison method: https://python.arviz.org/en/stable/user_guide/migration_guide.html#model-comparison
