Full Changelog: v2.0.4...v2.0.5

Version 2.0.4

This follows quickly on 2.0.3, which removed a feature and a function argument. Removing the feature is still the right thing to do (see the 2.0.3 release notes), but the function argument needs to go through a deprecation cycle, since libraries like dask-awkward pass arguments through to Awkward. Removing flatten_records as an argument introduces an error, even if the surviving case of flatten_records=False is desired.

This will also be a good exercise of the deprecation schedule in 2.x.

New features

(none!)

Bug-fixes and performance

• fix: soft-deprecate flatten_records instead of hard-deprecation by @agoose77 in #2036

Other

(none!)

Full Changelog: v2.0.3...v2.0.4

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.
