 FlatLaf Change Log
 ==================
 
+## 2.3
+
+#### New features and improvements
+
+- FileChooser: Added (optional) shortcuts panel. On Windows it contains "Recent
+  Items", "Desktop", "Documents", "This PC" and "Network". On macOS and Linux it
+  is empty/hidden. (issue #100)
+- Button and ToggleButton: Added missing foreground colors for hover, pressed,
+  focused and selected states. (issue #535)
+- Table: Optionally paint alternating rows below table if table is smaller than
+  scroll pane. Set UI value `Table.paintOutsideAlternateRows` to `true`.
+  Requires that `Table.alternateRowColor` is set to a color. (issue #504)
+- ToggleButton: Made the underline placement of tab-style toggle buttons
+  configurable. (PR #530; issue #529)
+- Added spanish translation. (PR #525)
+
+#### Fixed bugs
+
+- IntelliJ Themes: Fixed `TitledBorder` text color in "Monokai Pro" theme.
+  (issue #524)
+
+
+## 2.2
+
+#### New features and improvements
+
+- SplitPane: Allow limiting one-touch expanding to a single side (set client
+  property `JSplitPane.expandableSide` to `"left"` or `"right"`). (issue #355)
+- TabbedPane: Selected tab underline color now changes depending on whether the
+  focus is within the tab content. (issue #398)
+- IntelliJ Themes:
+  - Added "Monokai Pro" and "Xcode-Dark" themes.
+  - TabbedPane now use different background color for selected tabs in all "Arc"
+    themes, in "Hiberbee Dark" and in all "Material UI Lite" themes.
+
+#### Fixed bugs
+
+- Native window decorations (Windows 10/11 only): Fixed wrong window title
+  character encoding used in Windows taskbar. (issue #502)
+- Button: Fixed icon layout and preferred width of default buttons that use bold
+  font. (issue #506)
+- FileChooser: Enabled full row selection for details view to fix alternate row
+  coloring. (issue #512)
+- SplitPane: Fixed `StackOverflowError` caused by layout loop that may occur
+  under special circumstances. (issue #513)
+- Table: Slightly changed grid colors to make grid better recognizable. (issue
+  #514)
+- ToolBar: Fixed endless loop in focus navigation that may occur under special
+  circumstances. (issue #505)
+- IntelliJ Themes: `Component.accentColor` UI property now has useful theme
+  specific values. (issue #507)
+
+
+## 2.1
+
+#### New features and improvements
+
+- Menus: Improved usability of submenus. (PR #490; issue #247)
+- Menus: Scroll large menus using mouse wheel or up/down arrows. (issue #225)
+- Linux: Support using custom window decorations. Enable with
+  `JFrame.setDefaultLookAndFeelDecorated(true)` and
+  `JDialog.setDefaultLookAndFeelDecorated(true)` before creating a window.
+  (issue #482)
+- ScrollBar: Added UI value `ScrollBar.minimumButtonSize` to specify minimum
+  scroll arrow button size (if shown). (issue #493)
+
+#### Fixed bugs
+
+- PasswordField: Fixed reveal button appearance in IntelliJ themes. (issue #494)
+- ScrollBar: Center and scale arrows in scroll up/down buttons (if shown).
+  (issue #493)
+- TextArea, TextPane and EditorPane: No longer select all text when component is
+  focused for the first time. (issue #498; regression in FlatLaf 2.0)
+- TabbedPane: Disable all items in "Show Hidden Tabs" popup menu if tabbed pane
+  is disabled.
+
+#### Incompatibilities
+
+- Method `FlatUIUtils.paintArrow()` (and class `FlatArrowButton`) now paints
+  arrows one pixel smaller than before. To fix this, increase parameter
+  `arrowSize` by one.
