Changelog

Sourced from immutable's changelog.

5.1.9

• fix(List): a List grown past 32 elements while all its values are undefined no longer reads those values back as null (affected get, iteration, toArray, equals and hashCode)

5.1.8

• fix(List): guard oversized bounds in setListBounds. Fixes CVE GHSA-v56q-mh7h-f735
• perf(Map): index large hash-collision buckets for faster lookups. Fixes CVE GHSA-xvcm-6775-5m9r

4.3.9

• fix(List): guard oversized bounds in setListBounds. Fixes CVE GHSA-v56q-mh7h-f735
• perf(Map): index large hash-collision buckets for faster lookups. Fixes CVE GHSA-xvcm-6775-5m9r

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
