 FlatLaf Change Log
 ==================
 
+## 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.
+
+
+## 2.6
+
+#### New features and improvements
+
+- If value of system property `flatlaf.nativeLibraryPath` is `system`, then
+  `System.loadLibrary(String)` is used to load the native library.
+- TabbedPane: Switch and close tabs on left mouse click only. (PR #595)
+
+#### Fixed bugs
+
+- ComboBox and Spinner: Fixed missing arrow buttons if preferred height is zero.
+  Minimum width of arrow buttons is 3/4 of default width.
+- MenuBar: Fixed NPE in `FlatMenuItemRenderer.getTopLevelFont()` if menu item
+  does not have a parent. (issue #600; regression since implementing #589 in
+  FlatLaf 2.5)
+- ScrollBar: Show "pressed" feedback on track/thumb only for left mouse button.
+  If absolute positioning is enabled (the default), then also for middle mouse
+  button.
+- Arrow buttons in ComboBox, Spinner, ScrollBar and TabbedPane: Show "pressed"
+  feedback only for left mouse button.
+- ScaledImageIcon: Do not throw exceptions if image was has invalid size (e.g.
+  not found). Instead, paint a red rectangle (similar to `FlatSVGIcon`).
+- Fixed NPE in `FlatUIUtils.isCellEditor()`. (issue #601)
+
+
