 FlatLaf Change Log
 ==================
 
+## 0.34
+
+- Menus: New menu item renderer brings stable left margins, right aligned
+  accelerators and larger gap between text and accelerator. This makes menus
+  look more modern and more similar to native platform menus.
+- New underline menu selection style that displays selected menu items similar
+  to tabs (to enable use `UIManager.put( "MenuItem.selectionType", "underline"
+  );`).
+- Menus: Fixed text color of selected menu items that use HTML. (issue #87)
+- Menus: On Windows, pressing <kbd>F10</kbd> now activates the menu bar without
+  showing a menu popup (as usual on Windows platform). On other platforms the
+  first menu popup is shown.
+- Menus: On Windows, releasing <kbd>Alt</kbd> key now activates the menu bar (as
+  usual on Windows platform). (issue #43)
+- Menus: Fixed inconsistent left padding in menu items. (issue #3)
+- Menus: Fixed: Setting `iconTextGap` property on a menu item did increase left
+  and right margins. (issue #54)
+- Hide mnemonics if window is deactivated (e.g. <kbd>Alt+Tab</kbd> to another
+  window). (issue #43)
+- macOS: Enabled drop shadows for popup menus and combobox popups. (issue #94)
+- macOS: Fixed NPE if using `JMenuBar` in `JInternalFrame` and macOS screen menu
+  bar is enabled (with `-Dapple.laf.useScreenMenuBar=true`). (issue #90)
+
+
+## 0.33
+
+- Improved creation of disabled grayscale icons used in disabled buttons, labels
+  and tabs. They now have more contrast and are lighter in light themes and
+  darker in dark themes. (issue #70)
+- IntelliJ Themes: Fixed ComboBox size and Spinner border in all Material UI
+  Lite themes and limit tree row height in all Material UI Lite themes and some
+  other themes.
+- IntelliJ Themes: Material UI Lite themes did not work when using
+  [IntelliJ Themes Pack](flatlaf-intellij-themes) addon. (PR #88, issue #89)
+- IntelliJ Themes: Added Java 9 module descriptor to
+  `flatlaf-intellij-themes-<version>.jar`.
+
+
+## 0.32
+
+- New [IntelliJ Themes Pack](flatlaf-intellij-themes) addon bundles many popular
+  open-source 3rd party themes from JetBrains Plugins Repository into a JAR and
+  provides Java classes to use them.
+- IntelliJ Themes: Fixed button and toggle button colors. (issue #86)
+- Updated IntelliJ Themes in demo to the latest versions.
+- ToggleButton: Compute selected background color based on current component
+  background. (issue #32)
+
+
+## 0.31
+
+- Focus indication border (or background) no longer hidden when temporary
+  loosing focus (e.g. showing a popup menu).
+- List, Table and Tree: Item selection color of focused components no longer
+  change from blue to gray when temporary loosing focus (e.g. showing a popup
+  menu).
+
+
+## 0.30
+
+- Windows: Fixed rendering of Unicode characters. Previously not all Unicode
+  characters were rendered on Windows. (issue #81)
+
+
+## 0.29
+
+- Linux: Fixed scaling if `GDK_SCALE` environment variable is set or if running
+  on JetBrains Runtime. (issue #69)
+- Tree: Fixed repainting wide selection on focus gained/lost.
+- ComboBox: No longer ignore `JComboBox.prototypeDisplayValue` when computing
+  popup width. (issue #80)
+- Support changing default font used for all components with automatic scaling
+  UI if using larger font. Use `UIManager.put( "defaultFont", myFont );`
+- No longer use system property `sun.java2d.uiScale`. (Java 8 only)
+- Support specifying custom scale factor in system property `flatlaf.uiScale`
+  also for Java 9 and later.
+- Demo: Support using own FlatLaf themes (`.properties` files) that are located
+  in working directory of Demo application. Shown in the "Themes" list under
+  category "Current Directory".
+
+
