-- Use `@metamask/superstruct`, set `moduleResolution` to `NodeNext` ([#185](https://github.com/MetaMask/utils/pull/185))
-- Bump semver ([#181](https://github.com/MetaMask/utils/pull/181))
-- Use `ts-bridge` for building ([#182](https://github.com/MetaMask/utils/pull/182))
-- Bump tar from 6.1.11 to 6.2.1 ([#180](https://github.com/MetaMask/utils/pull/180))
+### Changed
+- Bump dependency `semver` from `^5.7.1` to `^7.6.0` ([#181](https://github.com/MetaMask/utils/pull/181)).
+
+### Fixed
+- Replace dependency `superstruct` `^1.0.3` with ESM-compatible `@metamask/superstruct` `^3.0.0` ([#185](https://github.com/MetaMask/utils/pull/185)).
+  - This fixes the issue of this package being unusable by any TypeScript project that uses `Node16` or `NodeNext` as its `moduleResolution` option.
+- Produce and export ESM-compatible TypeScript type declaration files in addition to CommonJS-compatible declaration files ([#182](https://github.com/MetaMask/utils/pull/182))
+  - Previously, this package shipped with only one variant of type declaration files, and these files were only CommonJS-compatible, and the `exports` field in `package.json` linked to these files. This is an anti-pattern and was rightfully flagged by the ["Are the Types Wrong?"](https://arethetypeswrong.github.io/) tool as ["masquerading as CJS"](https://github.com/arethetypeswrong/arethetypeswrong.github.io/blob/main/docs/problems/FalseCJS.md). All of the ATTW checks now pass.
+- Remove chunk files ([#182](https://github.com/MetaMask/utils/pull/182)).
+  - Previously, the build tool we used to generate JavaScript files extracted common code to "chunk" files. While this was intended to make this package more tree-shakeable, it also made debugging more difficult for our development teams. These chunk files are no longer present.
