 FlatLaf Change Log
 ==================
 
+## 0.18
+
+- TextField and TextArea: Do not apply minimum width if `columns` property is
+  greater than zero.
+- TabbedPane: In scroll-tab-layout, the separator line now spans the whole width
+  and is no longer interrupted by the scroll buttons.
+- TabbedPane: Content pane is no longer opaque. Use antialiasing for painting
+  separator and content border.
+- ToolTip: Use anti-aliasing to render multi-line tooltips.
+- JIDE Common Layer: Support `JideTabbedPane`.
+
+
+## 0.17
+
+- CheckBox: Support painting a third state (set client property
+  "JButton.selectedState" to "indeterminate").
+- `TriStateCheckBox` component added (see [FlatLaf Extras](flatlaf-extras)).
+- Made `JComboBox`, `JProgressBar`, `JSpinner` and `JXDatePicker` non-opaque.
+  `JPasswordField`, `JScrollPane` and `JTextField` are non-opaque if they have
+  an outside focus border (e.g. IntelliJ and Darcula themes). (issues #20 and
+  #17)
+- Button: Hover and pressed background colors are now derived from actual button
+  background color. (issue #21)
+- Table: Fixed missing upper right corner (e.g. in SwingX JXTable with column
+  control visible).
+
+
+## 0.16
+
+- Made some fixes for right-to-left support in ComboBox, Slider and ToolTip.
+  (issue #18)
+- Fixed Java 9 module descriptor (broken since 0.14).
+- Made `JButton`, `JCheckBox`, `JRadioButton`, `JToggleButton` and `JSlider`
+  non-opaque. (issue #20)
+
+
+## 0.15
+
+- ToolTip: Improved styling of dark tooltips (darker background, no border).
+- ToolTip: Fixed colors in tooltips of disabled components. (issue #15)
+- ComboBox: Fixed NPE in combobox with custom renderer after switching to
+  FlatLaf. (issue #16; regression in 0.14)
+
+
+## 0.14
+
+- ComboBox: Use small border if used as table editor.
+- ToolBar: Disable focusability of buttons in toolbar.
+- OptionPane: Fixed rendering of longer HTML text. (issue #12)
+- EditorPane and TextPane: Fixed font and text color when using HTML content.
+  (issue #9)
+- ComboBox: Fixed `StackOverflowError` when switching LaF. (issue #14)
+- SwingX: Support `JXBusyLabel`, `JXDatePicker`, `JXHeader`, `JXHyperlink`,
+  `JXMonthView`, `JXTaskPaneContainer` and `JXTaskPane`. (issue #8)
+
+
 ## 0.13

+FlatLaf addon for JIDE Common Layer
+===================================
+
+This addon for FlatLaf adds support for **some**
+[JIDE Common Layer](https://github.com/jidesoft/jide-oss) components.
+
+Following JIDE Common Layer components are currently supported by this addon:
+
+- `JideTabbedPane`
+
+
+**Note**: We have currently no plans to support additional components. If you're
+a paid customer of JFormDesigner and need support for other components, email to
+JFormDesigner support and ask for it. Otherwise, try to implement it yourself
+and create a pull request.
+
+
+Download
+--------
+
+FlatLaf for JIDE Common Layer binaries are available on **JCenter** and **Maven
+Central**.
+
+If you use Maven or Gradle, add a dependency with following coordinates to your
+build script:
+
+    groupId:     com.formdev
+    artifactId:  flatlaf-jide-oss
+    version:     0.18

+FlatLaf addon for SwingX
+========================
+
+This addon for FlatLaf adds support for **some** widely used SwingX components.
+
+Many SwingX components that do not use UI delegates (e.g. `JXButton`, `JXLabel`,
+`JXList`, etc) work with FlatLaf without adaptation.
+
+Following SwingX components, which use UI delegates, are currently supported by
+this addon:
+
+- `JXBusyLabel`
+- `JXDatePicker`
+- `JXHeader`
+- `JXHyperlink`
+- `JXMonthView`
+- `JXTaskPaneContainer`
+- `JXTaskPane`
+
+![Flat Light SwingX Demo](../images/FlatLightSwingXTest.png)
+
+![Flat Dark SwingX Demo](../images/FlatDarkSwingXTest.png)
+
+
+Download
+--------
+
+FlatLaf for SwingX binaries are available on **JCenter** and **Maven Central**.
+
+If you use Maven or Gradle, add a dependency with following coordinates to your
+build script:
+
+    groupId:     com.formdev
+    artifactId:  flatlaf-swingx
+    version:     0.18
+
+Otherwise download `flatlaf-swingx-<version>.jar` here:
+
+[![Download](https://api.bintray.com/packages/jformdesigner/flatlaf/flatlaf-swingx/images/download.svg)](https://bintray.com/jformdesigner/flatlaf/flatlaf-swingx/_latestVersion)
+
+You also need `flatlaf-<version>.jar`, which you can download here:
+
+[![Download](https://api.bintray.com/packages/jformdesigner/flatlaf/flatlaf/images/download.svg)](https://bintray.com/jformdesigner/flatlaf/flatlaf/_latestVersion)
