 FlatLaf Change Log
 ==================
 
+## 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)
+
+
+## 2.5
+
+#### New features and improvements
+
+- Linux: Use X11 window manager events to move window and to show window menu
+  (right-click on window title bar), if custom window decorations are enabled.
+  This gives FlatLaf windows a more "native" feeling. (issue #482)
+- MenuBar: Support different menu selection style UI defaults for `MenuBar` and
+  `MenuItem`. (issue #587)
+- MenuBar: Top level menus now use `MenuBar.font` instead of `Menu.font`. (issue
+  #589)
+- PasswordField: Reveal button is now hidden (and turned off) if password field
+  is disabled. (issue #501)
+- TabbedPane: New option to disable tab run rotation in wrap layout. Set UI
+  value `TabbedPane.rotateTabRuns` to `false`. (issue #574)
+- Window decorations:
+  - Added client property to mark components in embedded menu bar as "caption"
+    (allow moving window). (issue #569)
+  - Option to show window icon only in frames, but not in dialogs. Set UI value
+    `TitlePane.showIconInDialogs` to `false`. (issue #589)
+  - Added UI value `TitlePane.font` to customize window title font. (issue #589)
+- Added system property `flatlaf.updateUIOnSystemFontChange` to allow disabling
+  automatic UI update when system font changes. (issue #580)
+
+#### Fixed bugs
+
+- Fixed missing UI value `MenuItem.acceleratorDelimiter` on macOS. (was `null`,
+  is now an empty string)
+- Fixed possible exception in `FlatUIUtils.resetRenderingHints()`. (issue #575)
+- Fixed AWT components on macOS, which use Swing components internally. (issue
+  #583)
+- SwingX: Fixed missing highlighting of "today" in `JXMonthView` and
+  `JXDatePicker`.
