 FlatLaf Change Log
 ==================
 
+## 1.3
+
+#### New features and improvements
+
+- TextComponents, ComboBox and Spinner: Support different background color when
+  component is focused (use UI values `TextField.focusedBackground`,
+  `PasswordField.focusedBackground`, `FormattedTextField.focusedBackground`,
+  `TextArea.focusedBackground`, `TextPane.focusedBackground`,
+  `EditorPane.focusedBackground`, `ComboBox.focusedBackground`,
+  `ComboBox.buttonFocusedBackground`, `ComboBox.popupFocusedBackground` and
+  `Spinner.focusedBackground`). (issue #335)
+
+#### Fixed bugs
+
+- Fixed white lines at bottom and right side of window (in dark themes on HiDPI
+  screens with scaling enabled).
+- ScrollBar: Fixed left/top arrow icon location (if visible). (issue #329)
+- Spinner: Fixed up/down arrow icon location.
+- ToolTip: Fixed positioning of huge tooltips. (issue #333)
