 FlatLaf Change Log
 ==================
 
+## 3.1.1
+
+- IntelliJ Themes:
+  - Fixed too large menu item paddings and too large table/tree row heights (all
+    "Material Theme UI Lite" themes; issue #667; regression in FlatLaf 3.1).
+  - Fixed too large tree row height in "Carbon", "Dark Purple", "Gray",
+    "Material Design Dark", "Monokai Pro", "One Dark" and "Spacegray" themes.
+- Native libraries: Fixed `IllegalArgumentException: URI scheme is not "file"`
+  when using FlatLaf in WebStart. (issue #668; regression in FlatLaf 3.1)
+
+
+## 3.1
+
+#### New features and improvements
+
+- Windows 11: Popups (`JPopupMenu`, `JComboBox`, `JToolTip`, etc.) now use
+  native Windows 11 rounded borders and drop shadows. (PR #643)
+- Fonts:
+  - Added **Roboto Mono** (https://fonts.google.com/specimen/Roboto+Mono). (PR
+    #639, issue #638)
+  - Updated **JetBrains Mono** to
+    [v2.304](https://github.com/JetBrains/JetBrainsMono/releases/tag/v2.304).
+- Theme Editor: Support macOS light and dark themes.
+- TabbedPane: Support hover and focused tab foreground colors. (issue #627)
+- TabbedPane: `tabbedPane.getBackgroundAt(tabIndex)` now has higher priority
+  than `TabbedPane.focusColor` and `TabbedPane.selectedBackground`. If
+  `tabbedPane.setBackgroundAt(tabIndex)` is used to set a color for a single
+  tab, then this color is now used even if the tab is focused or selected.
+- TableHeader: Support column hover and pressed background and foreground
+  colors. (issue #636)
+- Native libraries: Made it easier to distribute FlatLaf native libraries
+  (Windows `.dll` and Linux `.so`) to avoid problems on operating systems with
+  enabled execution restrictions.
+  See https://www.formdev.com/flatlaf/native-libraries/ for more details. (issue #624)
+  - Published native libraries to Maven Central for easy using them as
+    dependencies in Gradle and Maven.
+  - If available, native libraries are now loaded from same location as
+    `flatlaf.jar`, otherwise they are extract from `flatlaf.jar` to temporary
+    folder and loaded from there.
+  - Windows DLLs are now digitally signed with FormDev Software GmbH
+    certificate.
+
+
+#### Fixed bugs
+
+- FlatLaf window decorations:
+  - Fixed inconsistent size of glass pane depending on whether FlatLaf window
+    decorations are used (e.g. Windows 10/11) or not (e.g. macOS). Now the glass
+    pane no longer overlaps the FlatLaf window title bar. (issue #630)
+  - Linux: Fixed broken window resizing on multi-screen setups. (issue #632)
+  - Linux: Fixed behavior of maximize/restore button when tiling window to left
+    or right half of screen. (issue #647)
+- IntelliJ Themes:
+  - Fixed default button hover background in "Solarized Light" theme. (issue
+    #628)
+  - Avoid that accent color affect some colors in some IntelliJ themes. (issue
+    #625)
+  - Updated "Hiberbee Dark" and "Material Theme UI Lite" themes.
+- Styling: Fixed resolving of UI variables in styles that use other variables.
+- MenuItem: Fixed horizontal alignment of icons. (issue #631)
+- Table: Fixed potential performance issue with paint cell focus indicator
+  border. (issue #654)
+- Tree: Fixed missing custom closed/opened/leaf icons of a custom
+  `DefaultTreeCellRenderer`. (issue #653; regression since implementing PR #609
+  in FlatLaf 3.0)
+- Tree: Fixed truncated node text and too small painted non-wide node background
+  if custom cell renderer sets icon, but not disabled icon, and tree is
+  disabled. (issue #640)
+- Fixed `HiDPIUtils.paintAtScale1x()`, which painted at wrong location if
+  graphics is rotated, is scaled and `x` or `y` parameters are not zero. (issue
+  #646)
+
+
+## 3.0
+
+#### New features and improvements
+
+- **macOS light and dark themes**: The two new themes `FlatMacLightLaf` and
+  `FlatMacDarkLaf` use macOS colors and look similar to native macOS controls.
+  (PRs #533, #612 and #607)
+- **Fonts**: Packaged some fonts into JARs and provide an easy way to use them
+  with FlatLaf. (PRs #545, #614 and #615) At the moment there are three fonts:
+  - **Inter** (https://rsms.me/inter/) - a typeface carefully crafted & designed
+    for computer screens
+  - **Roboto** (https://fonts.google.com/specimen/Roboto) - default font on
+    Android and recommended for Material Design
+  - **JetBrains Mono** (https://www.jetbrains.com/mono) - a monospaced typeface
+- **Rounded selection**: Optionally use rounded selection in:
+  - Menus (PR #536)
+  - ComboBox (PR #548)
+  - List (PR #547)
+  - Tree (PR #546)
+- Tree: Hide default closed/opened/leaf icons by default. Set UI value
+  `Tree.showDefaultIcons` to `true` to show them.
+- ToolBar: Hover effect for button groups. (PR #534)
+- Icons: New modern **rounded outlined icons** for `JFileChooser`,
+  `JOptionPane`, `JPasswordField` and `JTree`. (PR #577)
+
+#### Fixed bugs
+
+- FileChooser: Fixed layout of (optional) accessory component and fixed too
+  large right margin. (issue #604; regression since implementing PR #522 in
+  FlatLaf 2.3)
+- Tree:
+  - Fixed missing tree lines (if enabled) for wide-selected rows. (issue #598)
+  - Fixed scaling of tree lines and fixed alignment to expand/collapse arrows.
+  - Removed support for dashed tree lines. `Tree.lineTypeDashed` is now ignored.
+- SwingX: Fonts in `JXHeader`, `JXMonthView`, `JXTaskPane` and `JXTitledPanel`
+  were not updated when changing default font.
