 FlatLaf Change Log
 ==================
 
+## 0.44
+
+#### New features and improvements
+
+- TabbedPane: In scroll tab layout, added "Show Hidden Tabs" button to trailing
+  side of tab area. If pressed, it shows a popup menu that contains (partly)
+  hidden tabs and selecting one activates that tab. (PR #190; issue #40)
+- TabbedPane: Support forward/backward scroll arrow buttons on both sides of tab
+  area. Backward button on left side, forward button on right side. Not
+  applicable scroll buttons are hidden. (PR #211; issue #40)
+- TabbedPane: Support specifying default tab layout policy for all tabbed panes
+  in the application via UI value `TabbedPane.tabLayoutPolicy`. E.g. invoke
+  `UIManager.put( "TabbedPane.tabLayoutPolicy", "scroll" );` to use scroll
+  layout.
+- TabbedPane: Support tab scrolling with mouse wheel (in scroll tab layout). (PR
+  #187; issue #40)
+- TabbedPane: Repeat scrolling as long as scroll arrow buttons are pressed. (PR
+  #187; issue #40)
+- TabbedPane: Support adding custom components to left and right sides of tab
+  area. (set client property `JTabbedPane.leadingComponent` or
+  `JTabbedPane.trailingComponent` to a `java.awt.Component`) (PR #192; issue
+  #40)
+- TabbedPane: Support closable tabs. (PR #193; issues #31 and #40)
+- TabbedPane: Support minimum or maximum tab widths. (set client property
+  `JTabbedPane.minimumTabWidth` or `JTabbedPane.maximumTabWidth` to an integer)
+  (PR #199)
+- TabbedPane: Support alignment of tab area. (set client property
+  `JTabbedPane.tabAreaAlignment` to `"leading"`, `"trailing"`, `"center"` or
+  `"fill"`) (PR #199)
+- TabbedPane: Support horizontal alignment of tab title and icon. (set client
+  property `JTabbedPane.tabAlignment` to `SwingConstants.LEADING`,
+  `SwingConstants.TRAILING` or `SwingConstants.CENTER`)
+- TabbedPane: Support equal and compact tab width modes. (set client property
+  `JTabbedPane.tabWidthMode` to `"preferred"`, `"equal"` or `"compact"`) (PR
+  #199)
+- TabbedPane: Support left, right, top and bottom tab icon placement. (set
+  client property `JTabbedPane.tabIconPlacement` to `SwingConstants.LEADING`,
+  `SwingConstants.TRAILING`, `SwingConstants.TOP` or `SwingConstants.BOTTOM`)
+  (PR #199)
+- Support painting separator line between window title and content (use UI value
+  `TitlePane.borderColor`). (issue #184)
+- Extras: `FlatSVGIcon` now allows specifying icon width and height in
+  constructors. (issue #196)
+- SplitPane: Hide not applicable expand/collapse buttons. Added tooltips to
+  expand/collapse buttons. (issue #198)
+- SplitPane: Added grip to divider. Can be disabled with `UIManager.put(
+  "SplitPaneDivider.style", "plain" )`. (issue #179)
+
+
+#### Fixed bugs
+
+- Custom window decorations: Not visible menu bar is now ignored in layout.
+- Popups using `JToolTip` components did not respect their location. (issue
+  #188; regression in 0.42 in fix for #164)
+- IntelliJ Themes: Added suffix "(Material)" to names of all Material UI Lite
+  themes to avoid duplicate theme names. (issue #201)
+- Extras: `FlatSVGIcon` icons were not painted in disabled labels and disabled
+  tabs. (issue #205)
+
+
+## 0.43
+
+#### New features and improvements
+
+- TabbedPane: Made tabs separator color lighter in dark themes so that it is
+  easier to recognize the tabbed pane.
+- TabbedPane: Added top and bottom tab insets to avoid that large tab icons are
+  painted over active tab underline.
+- TabbedPane: Support hiding separator between tabs and content area (set client
+  property `JTabbedPane.showContentSeparator` to `false`).
+- CheckBoxMenuItem and RadioButtonMenuItem: Improved checkmark background colors
+  of selected menu items that have also an icon. This makes it is easier to
+  recognize selected menu items.
+- Windows: Made scaling compatible with Windows OS scaling, which distinguish
+  between "screen scaling" and "text scaling". (issue #175)
+
+#### Fixed bugs
+
+- ComboBox: If using own `JTextField` as editor, default text field border is
+  now removed to avoid duplicate border.
+- ComboBox: Limit popup width to screen width for very long items. (issue #182)
+- FileChooser: Fixed localizing special Windows folders (e.g. "Documents") and
+  enabled hiding known file extensions (if enabled in Windows Explorer). (issue
+  #178)
+- Spinner: Fixed `NullPointerException` in case that arrow buttons were removed
+  to create button-less spinner. (issue #181)
+
+
+## 0.42
+
+#### New features and improvements
+
+- Demo: Improved "SplitPane & Tabs" and "Data Components" tabs.
+- Demo: Menu items "File > Open" and "File > Save As" now show file choosers.
+- InternalFrame: Support draggable border for resizing frame inside of the
+  visible frame border. (issue #121)
+- `FlatUIDefaultsInspector` added (see [FlatLaf Extras](flatlaf-extras)). A
+  simple UI defaults inspector that shows a window with all UI defaults used in
+  current theme (look and feel).
+- Made disabled text color slightly lighter in dark themes for better
+  readability. (issue #174)
+- PasswordField: Support disabling Caps Lock warning icon. (issue #172)
+
+#### Fixed bugs
+
+- TextComponents: Fixed text color of disabled text components in dark themes.
+- Custom window decorations: Fixed wrong window placement when moving window to
+  another screen with different scaling factor. (issue #166)
+- Custom window decorations: Fixed wrong window bounds when resizing window to
+  another screen with different scaling factor. (issue #166)
+- Fixed occasional wrong positioning of heavy weight popups when using multiple
+  screens with different scaling factors. (issue #166)
+- ToolTip: Avoid that tooltip hides owner component. (issue #164)
+
+
+## 0.41
+
+#### New features and improvements
+
+- Added API to register packages or folders where FlatLaf searches for
+  application specific properties files with custom UI defaults (see
+  `FlatLaf.registerCustomDefaultsSource(...)` methods).
+- Demo: Show hint popups to guide users to some features of the FlatLaf Demo
+  application.
+- Extras: `FlatSVGIcon` now allows specifying `ClassLoader` that is used to load
+  SVG file. (issue #163)
+- Smoother transition from old to new theme, independent of UI complexity, when
+  using animated theme change (see [FlatLaf Extras](flatlaf-extras)).
+
+#### Fixed bugs
+
+- Button: "selected" state was not shown. (issue #161)
+- TextArea: Update background color property if enabled or editable state
+  changes in the same way as Swing does it for all other text components. (issue
+  #147)
+- Demo: Fixed restoring last used theme on startup. (regression in 0.39)
+- Custom window decorations: Fixed iconify, maximize and close icon colors if
+  window is inactive.
+- Custom window decorations: Fixed title pane background color in IntelliJ
+  themes if window is inactive.
+- Fixed sub-pixel text rendering in animated theme change (see
+  [FlatLaf Extras](flatlaf-extras)).
+
+#### Other Changes
+
+- Extras: Updated dependency
+  [svgSalamander](https://github.com/JFormDesigner/svgSalamander) to version
+  1.1.2.3.

+### UI Inspector
+
+A simple UI inspector that shows information about UI component at mouse
+location in a tooltip, which may be useful while developing an application.
+Should not be installed in released applications.
+
+Once installed with following code (e.g. in method `main`), it can be activated
+for the active window with the given keystroke:
+
+~~~java
+FlatInspector.install( "ctrl shift alt X" );
+~~~
+
+![UI inspector](../images/extras-FlatInspector.png)
+
+When the UI inspector is active some additional keys are available:
+
+- press <kbd>Esc</kbd> key to disable UI inspector
+- press <kbd>Ctrl</kbd> key to increase inspection level, which shows
+  information about parent of UI component at mouse location
+- press <kbd>Shift</kbd> key to decrease inspection level
+
+
+### UI Defaults Inspector
+
+A simple UI defaults inspector that shows a window with all UI defaults used in
+current theme (look and feel), which may be useful while developing an
+application. Should be not installed in released applications.
