+## [0.24.0] - 2024-10-21
+### Added
+- `SourceSpan` on nodes now have a `getInputIndex` to get the index within the
+  original input string (in addition to the existing line/column indexes).
+  This is useful when looking up the input source: It can now be done using
+  `substring` instead of having to split the input into lines first (#348)
+- Configurable line break rendering for `TextContentRenderer` via `lineBreakRendering`
+  on the builder; e.g. `LineBreakRendering.SEPARATE_BLOCKS` will render an empty
+  line between blocks (#344)
+### Changed
+- Adopted small changes from OpenJDK vendoring to make updates easier for them (#343)
+### Fixed
+- Enable overriding of built-in node rendering for `TextContentRenderer` (#346)
