Release Notes

toss/es-toolkit (es-toolkit)

v1.49.0

Compare Source

Released on June 26th, 2026.

• Added the es-toolkit/fp entrypoint with data-last, pipeable utilities,
  documentation, benchmarks, and bundle-size checks. ([#​1781])
• Added a broad set of array utilities to es-toolkit/fp, covering slicing,
  grouping, set operations, ordering, zipping, and collection helpers. ([#​1801])
• Fixed trimStart to validate multi-character trim strings correctly before
  it stops trimming. ([#​1615])
• Fixed compat/pick to prefer a literal key over a dot-notation path when the
  picked value is undefined. ([#​1775])
• Fixed compat/random to better match Lodash behavior for coerced bounds and
  floating-point options. ([#​1767])
• Fixed compat/chunk to handle NaN and Infinity size values consistently
  with Lodash. ([#​1797])
• Improved documentation and JSDoc accuracy across array, function, and compat
  references. ([#​1785], [#​1786], [#​1788], [#​1790], [#​1791], [#​1792], [#​1793],
  [#​1795], [#​1800])

v1.48.1

Compare Source

Released on June 21st, 2026.

• Fixed the jsdelivr and unpkg CDN <script> entry that regressed in v1.48.0. The fields are now declared at the package root so yarn pack preserves them, since publishConfig only carries standard fields and dropped them. Both CDNs now serve the UMD bundle again.

v1.48.0

Compare Source

Released on June 21st, 2026.

• Added AbortSignal support to timeout and withTimeout. ([#​1617])

• Fixed compat/toPath to keep empty segments for consecutive and trailing dots. ([#​1778])
• Fixed compat/difference to treat sparse array holes as undefined. ([#​1773])
