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

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

Dependency Upgrade Risk Assessment

Risk rating: dependency-upgrade-risk:low

What this library does

immutable (Immutable.js) provides persistent immutable data structures — Map, List, Set, Record, etc. — ensuring data cannot be mutated after creation.

Usage in seldon

No direct usage found in seldon source code. immutable is a transitive dependency.

Why this is LOW risk

The upgrade (5.0.3 → 5.1.9) covers a larger version range but all changes in the 5.x line are additive — new APIs and bug fixes with no breaking changes. Since seldon does not import or use immutable directly, the risk of any regression is minimal.

Regression tests to run before merging

  • Run npm run build to confirm the build completes successfully
  • Run npm run test to confirm all existing unit tests pass

Looks like immutable is up-to-date now, so this is no longer needed.

Superseded by #908 (merged) — the target version(s) are already at or above the proposed bump on main. Closing as duplicate.
