### Features
4+
5+
- Added support for TypeScript 5.3, #2446.
6+
- TypeDoc will now render interfaces as code at the top of the page describing interfaces, #2449.
7+
This can be controlled through the new `DefaultThemeRenderContext.reflectionPreview` helper.
8+
- Improved type rendering to highlight keywords differently than symbols.
9+

- `@example` tag titles will now be rendered in the example heading, #2440.
1219
- Correctly handle transient symbols in `@namespace`-created namespaces, #2444.
1320
- TypeDoc no longer displays the "Hierarchy" section if there is no inheritance hierarchy to display.
21+
- Direct links to individual signatures no longer results in the signature being partially scrolled off the screen.
