##### [v1.52.0](https://github.com/toss/es-toolkit/blob/HEAD/CHANGELOG.md#Version-v1520) Released on August 28th, 2026. - Added the `es-toolkit/iterator` entrypoint, a lazy iterator module with `chunk`, `count`, `dropWhile`, `head`, `iterate`, `partition`, `range`, `scan`, `takeWhile`, `uniqBy`, and `zip` (\[[#1815](toss/es-toolkit#1815)]), plus `cartesianProduct` (\[[#2031](toss/es-toolkit#2031)]). The same functions are also available from `es-toolkit/fp/iterator`. - Added `defer` and `deferAsync` to `es-toolkit/util`. (\[[#2032](toss/es-toolkit#2032)]) - Added `flowAsync` to `es-toolkit/fp`, a promise-aware left-to-right composition. (\[[#2033](toss/es-toolkit#2033)]) - Added the `EmptyObject`, `IsEqual`, `JSONValue`, `Primitive`, `SetOptional`, `SetRequired`, and `UnknownRecord` types. (\[[#2044](toss/es-toolkit#2044)]) - Fixed `merge` to infer the deep merged return type, and exported the `Merge` type. (\[[#1959](toss/es-toolkit#1959)]) - Fixed `omitBy` and `pickBy` to type numeric callback keys as strings, and exported the `ObjectKeys` type. (\[[#2037](toss/es-toolkit#2037)]) - Fixed `attempt` and `attemptAsync` to default their error type parameter to `unknown`. (\[[#2052](toss/es-toolkit#2052)]) The following bring `es-toolkit/compat` closer to Lodash. Behavior for the affected edge cases now matches Lodash, so results may differ if you relied on the previous output. - Fixed `compat/debounce` to skip the `maxWait` invocation when both `leading` and `trailing` are `false`. (\[[#1678](toss/es-toolkit#1678)]) - Fixed `compat/toString` to convert objects with a custom `valueOf`. (\[[#2034](toss/es-toolkit#2034)]) - Fixed `compat/mergeWith` to assign `null` values in array sources. (\[[#1929](toss/es-toolkit#1929)]) - Fixed `compat/has` and `compat/hasIn` to normalize the `-0` path key. (\[[#2035](toss/es-toolkit#2035)]) - Fixed `compat/differenceWith` and `compat/without` to normalize `-0` to `0`. (\[[#2049](toss/es-toolkit#2049)]) - Fixed `compat/findLastIndex` to convert `fromIndex` to an integer. (\[[#2047](toss/es-toolkit#2047)]) - Fixed `compat/xorWith` to match Lodash when no comparator is given. (\[[#2057](toss/es-toolkit#2057)]) - Covered the new iterator entrypoints in the dist and browser compatibility checks. (\[[#2030](toss/es-toolkit#2030)]) - Made the agent skills portable when installed on their own. (\[[#2054](toss/es-toolkit#2054)]) - Fixed documentation typos and the Deno install commands. (\[[#2062](toss/es-toolkit#2062)]) ##### [v1.51.0](https://github.com/toss/es-toolkit/blob/HEAD/CHANGELOG.md#Version-v1510) Released on August 17th, 2026. - Added the `es-toolkit/bigint` entrypoint: `bigint` counterparts of the math functions (`sum`, `sumBy`, `max`, `min`, `maxBy`, `minBy`, `clamp`, `inRange`, `median`, `medianBy`, `percentile`, `range`, `rangeRight`), kept separate so the `number` implementations stay unchanged. (\[[#1966](toss/es-toolkit#1966)]) - Added `dedent`, which removes common leading whitespace from template strings. (\[[#1679](toss/es-toolkit#1679)]) - Added `deepFreeze` for recursively freezing objects. (\[[#1680](toss/es-toolkit#1680)]) - Added `mapValuesAsync` and `mapKeysAsync`. (\[[#1544](toss/es-toolkit#1544)]) - Added `toPascalCaseKeys`, `toKebabCaseKeys`, and `toConstantCaseKeys`, completing the object key casing family. (\[[#1984](toss/es-toolkit#1984)]) - Exported the `ToCamelCaseKeys`, `ToPascalCaseKeys`, `ToSnakeCaseKeys`, `ToKebabCaseKeys`, and `ToConstantCaseKeys` types. (\[[#1651](toss/es-toolkit#1651)]) - Added a `preserveArrays` option to `flattenObject`. (\[[#974](toss/es-toolkit#974)]) - Fixed `retry` to pass the last error to the `delay` callback (\[[#1759](toss/es-toolkit#1759)]) and to throw the last attempt's error without applying a final delay (\[[#1901](toss/es-toolkit#1901)]). - Fixed `mergeWith` and `toMerged` to handle mixed array/object types consistently with `merge`. (\[[#2026](toss/es-toolkit#2026)]) - Fixed `pullAt` to remove the correct elements with negative indices. (\[[#1613](toss/es-toolkit#1613)]) - Fixed `at`, `pullAt`, `orderBy`, and `sortBy` to accept readonly arrays. (\[[#2016](toss/es-toolkit#2016)]) - Moved `limitAsync` from the array to the promise category. (\[[#2022](toss/es-toolkit#2022)]) - Included the NOTICE file in the published npm and JSR packages. (\[[#2020](toss/es-toolkit#2020)]) The following bring `es-toolkit/compat` closer to Lodash. Behavior for the affected edge cases now matches Lodash, so results may differ if you relied on the previous output. - Added `entries` and `entriesIn`. (\[[#1874](toss/es-toolkit#1874)]) - Fixed `compat/isMatch` and `compat/isMatchWith` to handle object source patterns against primitive and non-plain-object targets like Lodash. (\[[#1432](toss/es-toolkit#1432)]) - Fixed `compat/set` to block `constructor.prototype` paths, preventing prototype pollution. (\[[#1904](toss/es-toolkit#1904)]) - Fixed `compat/find` to respect array-like `length` (\[[#1958](toss/es-toolkit#1958)]) and to convert `fromIndex` to an integer (\[[#1961](toss/es-toolkit#1961)]), and `compat/indexOf` to convert `fromIndex` to an integer when searching for `NaN` (\[[#1951](toss/es-toolkit#1951)]). - Fixed `compat/orderBy` to resolve unresolved deep paths and nullish elements to `undefined` (\[[#2010](toss/es-toolkit#2010)]), to exclude the `length` property from array-like values (\[[#2002](toss/es-toolkit#2002)]), and to read the criterion property from primitive values (\[[#1903](toss/es-toolkit#1903)]). - Fixed `compat/toPath` to split unquoted dotted keys inside brackets. (\[[#1899](toss/es-toolkit#1899)]) - Fixed `compat/omit` to treat a key array as a single deep path. (\[[#1902](toss/es-toolkit#1902)]) - Fixed `compat/map` to make the iteratee optional with an identity default. (\[[#1928](toss/es-toolkit#1928)]) - Fixed `compat/size` to count combined Unicode symbols as single characters. (\[[#1900](toss/es-toolkit#1900)]) - Fixed `compat/intersectionBy` to support number, object, and nullish iteratee shorthands (\[[#1993](toss/es-toolkit#1993)]), and `compat/intersectionWith` to apply the comparator when deduplicating the first array (\[[#1953](toss/es-toolkit#1953)]). - Fixed `compat/difference`, `compat/differenceBy`, `compat/uniqBy`, and `compat/unionBy` to normalize `-0` to `0`. (\[[#2007](toss/es-toolkit#2007)]) - Fixed `compat/maxBy` and `compat/minBy` to skip nullish iteratee values (\[[#1927](toss/es-toolkit#1927)]), and `compat/meanBy` to skip `undefined` values when averaging (\[[#1978](toss/es-toolkit#1978)]). - Fixed `compat/some`, `compat/template` (\[[#2009](toss/es-toolkit#2009)]), and `compat/fill` (\[[#1952](toss/es-toolkit#1952)]) to gate guard handling with `isIterateeCall`. - Fixed `compat/iteratee` to treat a boolean as a property shorthand. (\[[#1941](toss/es-toolkit#1941)]) - Fixed `compat/reverse` to support array-like objects and `arguments`. (\[[#2008](toss/es-toolkit#2008)]) - Fixed `compat/toArray` to convert non-array-like iterables. (\[[#1999](toss/es-toolkit#1999)]) - Fixed `compat/toString` to render nested nullish values like Lodash. (\[[#1992](toss/es-toolkit#1992)]) - Fixed `compat/zipObject` to treat `null` keys and values as empty arrays. (\[[#2005](toss/es-toolkit#2005)]) - Fixed `compat/sampleSize` to clamp the default size to the collection length. (\[[#2003](toss/es-toolkit#2003)]) - Fixed `compat/takeWhile`, `compat/takeRightWhile`, and `compat/uniqBy` to support string inputs. (\[[#2004](toss/es-toolkit#2004)]) - Fixed `compat/chunk` to return an empty array for an empty collection with an `Infinity` size. (\[[#1995](toss/es-toolkit#1995)]) - Fixed `compat/lastIndexOf` to read holes in sparse arrays as `undefined`. (\[[#1977](toss/es-toolkit#1977)]) - Fixed `compat/last` to return `undefined` for empty array-like inputs. (\[[#1954](toss/es-toolkit#1954)]) - Fixed `compat/pullAll` to return the array as-is when `values` is nullish. (\[[#1962](toss/es-toolkit#1962)]) - Added a browser compatibility test suite. (\[[#2012](toss/es-toolkit#2012)]) - Improved documentation, JSDoc accuracy, tests, and internal refactoring across `compat` and the docs site. (\[[#1622](toss/es-toolkit#1622)], \[[#1789](toss/es-toolkit#1789)], \[[#1824](toss/es-toolkit#1824)], \[[#1844](toss/es-toolkit#1844)], \[[#1849](toss/es-toolkit#1849)], \[[#1854](toss/es-toolkit#1854)], \[[#1855](toss/es-toolkit#1855)], \[[#1859](toss/es-toolkit#1859)], \[[#1860](toss/es-toolkit#1860)], \[[#1868](toss/es-toolkit#1868)], \[[#1871](toss/es-toolkit#1871)], \[[#1887](toss/es-toolkit#1887)], \[[#1898](toss/es-toolkit#1898)], \[[#1933](toss/es-toolkit#1933)], \[[#1939](toss/es-toolkit#1939)], \[[#1947](toss/es-toolkit#1947)], \[[#1950](toss/es-toolkit#1950)], \[[#1955](toss/es-toolkit#1955)], \[[#1956](toss/es-toolkit#1956)], \[[#1957](toss/es-toolkit#1957)], \[[#1960](toss/es-toolkit#1960)], \[[#1963](toss/es-toolkit#1963)], \[[#1964](toss/es-toolkit#1964)], \[[#1968](toss/es-toolkit#1968)], \[[#1969](toss/es-toolkit#1969)], \[[#1970](toss/es-toolkit#1970)], \[[#1972](toss/es-toolkit#1972)], \[[#1979](toss/es-toolkit#1979)], \[[#1985](toss/es-toolkit#1985)], \[[#2000](toss/es-toolkit#2000)], \[[#2001](toss/es-toolkit#2001)], \[[#2021](toss/es-toolkit#2021)], \[[#2025](toss/es-toolkit#2025)], \[[#2027](toss/es-toolkit#2027)]) We sincerely thank [@Antoliny0919](https://github.com/Antoliny0919), [@D-Sketon](https://github.com/D-Sketon), [@kojesung](https://github.com/kojesung), [@chuenchen309](https://github.com/chuenchen309), [@mariazuheros](https://github.com/mariazuheros), [@DongEun02](https://github.com/DongEun02), [@raon0211](https://github.com/raon0211), [@sukvvon](https://github.com/sukvvon), [@racgoo](https://github.com/racgoo), [@dayongkr](https://github.com/dayongkr), [@Kropiunig](https://github.com/Kropiunig), [@ssi02014](https://github.com/ssi02014), [@sarathfrancis90](https://github.com/sarathfrancis90), [@mym0404](https://github.com/mym0404), [@mlnwns](https://github.com/mlnwns), [@kdelay](https://github.com/kdelay), [@gwagjiug](https://github.com/gwagjiug), [@dohwi](https://github.com/dohwi), [@blro0319](https://github.com/blro0319), [@benedictleejh](https://github.com/benedictleejh), [@amir-rezaei](https://github.com/amir-rezaei), [@ianzone](https://github.com/ianzone), [@sen2y](https://github.com/sen2y), [@rossyman](https://github.com/rossyman), [@eunwoo-levi](https://github.com/eunwoo-levi), [@ramong26](https://github.com/ramong26), [@Gdm0714](https://github.com/Gdm0714), and everyone else who contributed.
