What’s new in 3.0.2 (March 30, 2026)#

These are the changes in pandas 3.0.2. See Release notes for a full changelog including other versions of pandas.

Enhancements#

Fixed regressions#

  • Fixed a regression in json_normalize() that caused top-level missing entries to raise a TypeError. Missing entries are once again interpreted as empty records (GH 64188)

  • Fixed a regression in DataFrame.sort_index() and Series.sort_index() raising AssertionError when called with level= on a RangeIndex (GH 64383)

  • Fixed a regression in DataFrame.sum() on empty DataFrames with a mix of numeric and string dtypes (GH 64657)

  • Fixed a regression in HDFStore.select() where the where clause on a datetime index silently returned empty results when the index had non-nanosecond resolution (GH 64310)

  • Fixed a regression in Series.interpolate() where limit_direction="both" with limit greater than the Series length raised ValueError (GH 64322)

  • Fixed a regression in Series.str.find() returning byte offsets instead of character offsets for multi-byte UTF-8 characters (GH 64123)

  • Fixed performance regression in assigning into a string column with string data (GH 64530)

Bug fixes#

  • Fixed a bug in Series.var() computing the variance of complex numbers incorrectly (GH 62421)

  • Fixed a bug in the sum() method with python-backed string dtype returning incorrect value for an empty Series and ignoring the min_count argument (GH 64683)

  • Fixed a bug when using col() with Python functions bool(), iter(), copy(), and deepcopy() either failed or produced incorrect results; these now all raise a TypeError (GH 64267)

  • Fixed a bug where col() and expressions derived from it failed with power (**) and matrix multiplication (@) operators (GH 64267)

  • Fixed a bug where DataFrame.div() ignored the axis argument when used with level for MultiIndex columns (GH 64428)

  • Fixed a bug where assigning NA to a string column could trigger a PyArrow error and corrupt data (GH 64320)
