### New APIs and options

### Tooling

- Support was added for the new d.ts extension format when using TypeScript moduleResolution bundler or nodenext. (7.58.8) — [release notes](https://github.com/microsoft/rushstack/blob/9b27e7ab3c987fdf023e10fa326cba4c1020bf9a/apps/api-extractor/CHANGELOG.md#7588)

### Fixes and other changes

- Fixes empty lines appearing in DTS rollups in place of API items that were trimmed. (7.58.6) — [release notes](https://github.com/microsoft/rushstack/blob/9b27e7ab3c987fdf023e10fa326cba4c1020bf9a/apps/api-extractor/CHANGELOG.md#7586)
