 ## 3.7.1-SNAPSHOT
 
-- System File Chooser:
-  - Update current filter before invoking approve callback and after closing
-    dialog. (issue #1065)
-  - Added `PatternFilter` to support glob file filter (e.g. `*.tar.gz`) on
-    Windows and on Linux, but not on macOS. (issue #1076)
-  - Fixed: System and Swing file dialogs were shown at the same time if
-    application has no other displayable window. (issue #1078)
-  - On Linux: Check whether required GSettings schemas are installed to avoid
-    application crash (occurred on NixOS with Plasma/KDE desktop). (issue #1069)
 - ComboBox: Added UI property `ComboBox.buttonFocusedEditableBackground`. (issue
   #1068)
 - Popup: Fixed scrolling popup painting issue on Windows 10 when a glass pane is
   visible and frame is maximized. (issue #1071)
+- Slider: Styling `thumbSize` or `focusWidth` did not update slider size/layout.
+  (PR #1074)
+- ToolBar: Grip disappeared when switching between Look and Feels. (issue #1075)
+- Extras:
+  - UI defaults inspector: Fixed NPE if color of `FlatLineBorder` is null. Also
+    use `FlatLineBorder` line color as cell background color in "Value" column.
+    (PR #1080)
+  - `FlatDesktop`: Avoid unnecessary logging if desktop is not supported (e.g.
+    on NixOS with Plasma/KDE desktop).
