 FlatLaf Change Log
 ==================

+## 0.22
+
+- TextComponent: Support placeholder text that is displayed if text field is
+  empty (set client property "JTextField.placeholderText" to a string).
+- TextComponent: Scale caret width on HiDPI screens when running on Java 8.
+- ProgressBar: If progress text is visible:
+  - use smaller font
+  - reduced height
+  - changed style to rounded rectangle
+  - fixed painting issues on low values
+- ProgressBar: Support configure of arc with `ProgressBar.arc`.
+- ProgressBar: Reduced thickness from 6 to 4.
+- TabbedPane: Support background color for selected tabs
+  (`TabbedPane.selectedBackground`) and separators between tabs
+  (`TabbedPane.showTabSeparators`).
+- CheckBox: changed `CheckBox.arc` from radius to diameter to be consistent with
+  `Button.arc` and `Component.arc`
+- Button: Enabled `Button.defaultButtonFollowsFocus` on Windows, which allows
+  pressing focused button with <kbd>Enter</kbd> key (as in Windows LaF).
+- Fixed clipped borders at 125%, 150% and 175% scaling when outer focus width is
+  zero (default in "Flat Light" and "Flat Dark" themes).
+- On Mac show mnemonics only when <kbd>Ctrl</kbd> and <kbd>Alt</kbd> keys are
+  pressed. (issue #4)
+
+
