 FlatLaf Change Log
 ==================
 
+## 0.35
+
+- Added drop shadows to popup menus, combobox popups, tooltips and internal
+  frames. (issue #94)
+- Support different component border colors to indicate errors, warnings or
+  custom state (set client property `JComponent.outline` to `error`, `warning`
+  or any `java.awt.Color`).
+- Button and ToggleButton: Support round button style (set client property
+  `JButton.buttonType` to `roundRect`).
+- ComboBox, Spinner and TextField: Support round border style (set client
+  property `JComponent.roundRect` to `true`).
+- Paint nicely rounded buttons, comboboxes, spinners and text fields when
+  setting `Button.arc`, `Component.arc` or `TextComponent.arc` to a large value
+  (e.g. 1000).
+- Added Java 9 module descriptor to `flatlaf-extras-<version>.jar` and
+  `flatlaf-swingx-<version>.jar`.
+- CheckBox and RadioButton: Flag `opaque` is no longer ignored when checkbox or
+  radio button is used as table cell renderer. (issue #77)
+- FileChooser: Use system icons. (issue #100)
+- FileChooser: Fixed missing labels in file chooser when running on Java 9 or
+  later. (issue #98)
+- PasswordField: Do not apply minimum width if `columns` property is greater
+  than zero.
+
