 FlatLaf Change Log
 ==================
 
+## 1.4
+
+#### New features and improvements
+
+- TextField, FormattedTextField and PasswordField: Support adding extra padding.
+  (set client property `JTextField.padding` to `Insets`).
+- PasswordField: UI delegate `FlatPasswordFieldUI` now extends `FlatTextFieldUI`
+  (instead of `BasicPasswordFieldUI`) to avoid duplicate code and for easier
+  extensibility.
+- Table and PopupFactory: Use `StackWalker` in Java 9+ for better performance.
+  (issue #334)
+- ToolBar: Paint focus indicator for focused button in toolbar. (issue #346)
+- ToolBar: Support focusable buttons in toolbar (set UI values
+  `ToolBar.focusableButtons` to `true`). (issue #346)
+
+#### Fixed bugs
+
+- ComboBox (editable) and Spinner: Increased size of internal text field to the
+  component border so that it behaves like plain text field (mouse click to left
+  of text now positions caret to first character instead of opening ComboBox
+  popup; mouse cursor is now of type "text" within the whole component, except
+  for arrow buttons). (issue #330)
+- ComboBox (not editable): Increased size of internal renderer pane to the
+  component border so that it can paint within the whole component. Also
+  increase combo box size if a custom renderer uses a border with insets that
+  are larger than the default combo box padding (`2,6,2,6`).
+- Fixed component heights at `1.25x`, `1.75x` and `2.25x` scaling factors (Java
+  8 only) so that Button, ComboBox, Spinner and TextField components (including
+  subclasses) have same heights. This increases heights of Button and TextField
+  components by:
+  - `2px` at `1.75x` in **Light** and **Dark** themes
+  - `2px` at `1.25x` and `2.25x` in **IntelliJ** and **Darcula** themes
+- OptionPane: Do not make child components, which are derived from `JPanel`,
+  non-opaque. (issue #349)
+- OptionPane: Align wrapped lines to the right if component orientation is
+  right-to-left. (issue #350)
+- PasswordField: Caps lock icon no longer painted over long text. (issue #172)
+- PasswordField: Paint caps lock icon on left side in right-to-left component
+  orientation.
+- Window decorations: Window title bar width is no longer considered when
+  calculating preferred/minimum width of window. (issue #351)
+
+
+## 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.popupBackground` 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)
+
+
+## 1.2
+
+#### New features and improvements
+
+- Renamed `Flat*Laf.install()` methods to `Flat*Laf.setup()` to avoid confusion
+  with `UIManager.installLookAndFeel(LookAndFeelInfo info)`. The old
+  `Flat*Laf.install()` methods are still there, but marked as deprecated. They
+  will be removed in a future version.
+- Button and ToggleButton: Support borderless button style (set client property
+  `JButton.buttonType` to `borderless`). (PR #276)
+- ComboBox: Support using as cell renderer (e.g. in `JTable`).
+- DesktopPane: Improved layout of iconified internal frames in dock:
+  - Always placed at bottom-left in desktop pane.
+  - Newly iconified frames are added to the right side of the dock.
+  - If frame is deiconified, dock is compacted (icons move to the left).
+  - If dock is wider than desktop width, additional rows are used.
+  - If desktop pane is resized, layout of dock is updated.
+- TableHeader: Moved table header column border painting from
+  `FlatTableHeaderUI` to new border `FlatTableHeaderBorder` to improve
+  compatibility with custom table header implementations. (issue #228)
+- Linux: Enable text anti-aliasing if no Gnome or KDE Desktop properties are
+  available. (issue #218)
+- IntelliJ Themes: Added "Material Theme UI Lite / GitHub Dark" theme.
+- JIDE Common Layer: Improved support for `JideTabbedPane`. (PR #306)
+- Extras: `FlatSVGIcon` improvements:
+  - Each icon can now have its own color filter. (PR #303)
+  - Use mapper function in color filter to dynamically map colors. (PR #303)
+  - Color filter supports light and dark themes.
+  - Getters for icon name, classloader, etc.
+- Extras: UI Inspector: Show class hierarchies when pressing <kbd>Alt</kbd> key
+  and prettified class names (dimmed package name).
+- Extras: `FlatSVGUtils.createWindowIconImages()` now returns a single
+  multi-resolution image that creates requested image sizes on demand from SVG
+  (only on Windows with Java 9+).
+
+#### Fixed bugs
+
+- CheckBox and RadioButton: Do not fill background if used as cell renderer,
+  except if cell is selected or has different background color. (issue #311)
+- DesktopPane:
+  - Fixed missing preview of iconified internal frames in dock when using a
+    custom desktop manager. (PR #294)
+  - Fixed incomplete preview of iconified internal frames in dock when switching
+    LaF.
+  - On HiDPI screens, use high-resolution images for preview of iconified
+    internal frames in dock.
+- PopupFactory: Fixed occasional `NullPointerException` in
+  `FlatPopupFactory.fixToolTipLocation()`. (issue #305)
+- Tree: Fill cell background if
+  `DefaultTreeCellRenderer.setBackgroundNonSelectionColor(Color)` was used.
+  (issue #322)
+- IntelliJ Themes: Fixed background colors of DesktopPane and DesktopIcon in all
+  themes.
+- Native window decorations:
+  - Fixed slow application startup under particular conditions. (e.g. incomplete
+    custom JRE) (issue #319)
+  - Fixed occasional double window title bar when creating many frames or
+    dialogs. (issue #315)
+  - Fixed broken maximizing window (under special conditions) when restoring
+    frame state at startup.
+  - Title icon: For multi-resolution images now use `getResolutionVariant(width,
+    height)` (instead of `getResolutionVariants()`) to allow creation of
+    requested size on demand. This also avoids creation of all resolution
+    variants.
+  - Double-click at upper-left corner of maximized frame did not close window.
+    (issue #326)
+- Linux: Fixed/improved detection of user font settings. (issue #309)
+
+
