+# JavaFX 23 Highlights
+
+JavaFX version 23 has been released. We've tailored down some of the most exciting parts of the release in this document.
+
+### JavaFX 23 Requires JDK 21 or later
+
+JavaFX 23 is compiled with `--release 21` and thus requires JDK 21 or later in order to run.
+If you attempt to run with an older JDK, the Java launcher will exit with an error message indicating that the `javafx.base` module cannot be read.
+
+See [JDK-8321603](https://bugs.openjdk.org/browse/JDK-8321603) for more information.
+
+### Clicking on the Scrollbar Track of Virtualized Controls Scrolls by Viewport Length
+
+Clicking on the scrollbar track of virtualized controls, such as `ListView`, `TreeView`, `TableView`, and `TreeTableView`,
+now scrolls by the viewport length rather than the length of the empty cell.
+Furthermore, cells are no longer aligned to the top or bottom of the viewport after scrolling.
+
+See [JDK-8323511](https://bugs.openjdk.org/browse/JDK-8323511) for more information.
+
+### Keyboard Scrolling in Virtualized Controls
+
+Keyboard scrolling key bindings, `alt-ctrl-arrows` (`option-command-arrows` on macOS),
+have been added to virtualized controls such as  `ListView`, `TreeView`, `TableView`, and `TreeTableView` to improve accessibility.
+
+See [JDK-8313138](https://bugs.openjdk.org/browse/JDK-8313138) for more information.
+
+Exciting features:
+- New APIs:
+  - Labeled control now has `textTruncated` property which indicates when the text is visually truncated in order to fit the available width
+
+- New Features:
+  - CSS Transition support in JavaFX, making it easy to define animated transitions for creating rich and fluid user experiences
+  - Support "@3x" and greater high-density image naming convention
+  - Add support for EXT-X-MEDIA tag in HTTP Live Streaming
+
+Improvements:
+- JavaFX CSS has been receiving multiple performance improvements.
+In JavaFX 22 highlights, we talked about performance improvements for css rendering.
+JavaFX 23 has performance improvements for CSS selector matching
+
+The community came together to fix 81 bugs in the last 6 months. Following are major bug-fixes that went into JavaFX 23:
+
+- Fix for scrolling failure on a touch enabled display on Wayland
+- Fix for ConcurrentModificationException in MediaPlayer which can lead to application crashes or unexpected behavior in media application
+- Fix HLS video stream to render consistently
+- Fix for `KeyEvent.getCode()` is `null` inside JFXPanel, affecting Swing/JavaFX integration
+
+Finally, these are some dependency upgrades in JavaFX 23:
+- Upgraded WebKit to 617.1
+- Upgraded ICU4C to 74.2
+- Upgraded SQLite to 3.45.3
+- Upgraded libxml2 to 2.12.7
+
