Changelog

Sourced from immutable's changelog.

4.3.9

5.1.7

  • fix(Repeat): lastIndexOf returned size instead of size - 1 by @​chatman-media in immutable-js/immutable-js#2227. Fixes CVE CVE-2026-29063
  • fix(IndexedCollection): has(index) on a lazy Seq of unknown size now checks index existence instead of searching for a value equal to the index #2203
  • [TypeScript]: reduce/reduceRight without an initial value now infer the result type from the collection's values when the reducer returns a value (e.g. list.reduce((a, b) => a + b) infers number), matching Array#reduce. Previously an explicit type argument was required. #2205

5.1.6

  • fix(reverseFactory): read reversedSequence.size in __iterator instead of this #2196

5.1.5

  • Fix Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution') in immutable

5.1.4
