 FlatLaf Change Log
 ==================
 
+## 0.46
+
+#### New features and improvements
+
+- Slider and JIDE RangeSlider: Clicking on track now immediately moves the thumb
+  to mouse location and starts dragging the thumb. Use `UIManager.put(
+  "Slider.scrollOnTrackClick", true )` to enable old behavior that scrolls the
+  thumb when clicking on track.
+- Slider: Snap to ticks is now done while dragging the thumb. Use
+  `UIManager.put( "Slider.snapToTicksOnReleased", true )` to enable old behavior
+  that snaps to ticks on mouse released.
+- Extras: Added standard component extension classes that provides easy access
+  to FlatLaf specific client properties (see package
+  `com.formdev.flatlaf.extras.components`).
+- Extras: Renamed tri-state check box class from
+  `com.formdev.flatlaf.extras.TriStateCheckBox` to
+  `com.formdev.flatlaf.extras.components.FlatTriStateCheckBox`. Also
+  changed/improved API and added javadoc.
+- Extras: Renamed SVG utility class from `com.formdev.flatlaf.extras.SVGUtils`
+  to `com.formdev.flatlaf.extras.FlatSVGUtils`.
+- IntelliJ Themes: Added flag whether a theme is dark to
+  `FlatAllIJThemes.INFOS`. (issue #221)
+- JIDE Common Layer: Support `TristateCheckBox`.
+
+
+#### Fixed bugs
+
+- Slider: Fixed painting of colored track if `JSlider.inverted` is `true`.
+- Table and TableHeader: Fixed missing right vertical grid line if using table
+  as row header in scroll pane. (issues #152 and #46)
+- TableHeader: Fixed position of column separators in right-to-left component
+  orientation.
+- ToolTip: Fixed drop shadow for wide tooltips on Windows and Java 9+. (issue
+  #224)
+- SwingX: Fixed striping background highlighting color (e.g. alternating table
+  rows) in dark themes.
+- Fixed: If text antialiasing is disabled (in OS system settings or via
+  `-Dawt.useSystemAAFontSettings=off`), then some components still did use
+  antialiasing to render text (not-editable ComboBox, ProgressBar, Slider,
+  TabbedPane and multiline ToolTip). (issue #227)
+
+
+## 0.45
+
+#### New features and improvements
+
+- Slider: New design, added hover and pressed feedback and improved customizing.
+  (PR #214)
+- JIDE Common Layer: Support `RangeSlider`. (PR #209)
+- IntelliJ Themes:
+  - Added "Gradianto Nature Green" theme.
+  - Updated "Arc Dark", "Cyan", "Dark purple", "Gradianto", "Gray", "Gruvbox"
+    and "One Dark" themes.
+- TabbedPane: Support hiding tab area if it contains only one tab. (set client
+  property `JTabbedPane.hideTabAreaWithOneTab` to `true`)
+- MenuBar: Support different underline menu selection style UI defaults for
+  `MenuBar` and `MenuItem`. (PR #217; issue #216)
+
+
+#### Fixed bugs
+
+- Table: Do not paint last vertical grid line if auto-resize mode is not off.
+  (issue #46)
+- Table: Fixed unstable grid line thickness when scaled on HiDPI screens. (issue
+  #152)
+- TabbedPane: No longer add (internal) tab close button component as child to
+  `JTabbedPane`. (issue #219)
+- Custom window decorations: Title bar was not hidden if window is in
+  full-screen mode. (issue #212)
+
+
