+## **6.14.2**
+- [Fix] `parse`: mark overflow objects for indexed notation exceeding `arrayLimit` (#546)
+- [Fix] `arrayLimit` means max count, not max index, in `combine`/`merge`/`parseArrayValue`
+- [Fix] `parse`: throw on `arrayLimit` exceeded with indexed notation when `throwOnLimitExceeded` is true (#529)
+- [Fix] `parse`: enforce `arrayLimit` on `comma`-parsed values
+- [Fix] `parse`: fix error message to reflect arrayLimit as max index; remove extraneous comments (#545)
+- [Robustness] avoid `.push`, use `void`
+- [readme] document that `addQueryPrefix` does not add `?` to empty output (#418)
+- [readme] clarify `parseArrays` and `arrayLimit` documentation (#543)
+- [readme] replace runkit CI badge with shields.io check-runs badge
+- [meta] fix changelog typo (`arrayLength` → `arrayLimit`)
+- [actions] fix rebase workflow permissions
+
 ## **6.14.1**
-- [Fix] ensure arrayLength applies to `[]` notation as well
+- [Fix] ensure `arrayLimit` applies to `[]` notation as well
 - [Fix] `parse`: when a custom decoder returns `null` for a key, ignore that key
 - [Refactor] `parse`: extract key segment splitting helper
 - [meta] add threat model
