Version 2.0.3

Backward-incompatible changes

• The flatten_records argument of all reducers (ak.all, ak.any, ..., ak.var) has effectively been removed: setting it now raises an error (PR #2020). This argument applies a reducer to all contents of a record, merging fields, and it had to be removed to properly implement axis=None. The old default, flatten_records=False, is now the only behavior, and to get the equivalent of flatten_records=True, you can use ak.ravel:

ak.sum(array, flatten_records=True)

becomes

ak.sum(ak.ravel(array))

Note: yanked from PyPI in favor of 2.0.4.
