+

+
+.NET 11 Preview 6 does not introduce new Windows Forms feature additions.
+
+## Bug fixes
+
+**`System.Windows.Forms.PropertyGrid`**
+* `SelectedObjects` now displays typed arrays correctly when `PropertySort` is set to `NoSort`
+(dotnet/winforms #14190).
+• `SelectedTab` now changes correctly when a new `SelectedObject` is assigned
+(dotnet/winforms #14438).
+• The cursor editor now caches its scaled icon size, preventing GDI resource exhaustion when it is resized
+(dotnet/winforms #14123).
+
+**`System.Windows.Forms.ToolStrip`**
+* `ToolStripDropDown` now preserves modal menu tracking during focus changes. This lets SmartTag and dropdown UI close normally when users switch tab
+pages or otherwise move focus 
+(dotnet/winforms #14606).
+* `ToolStrip` controls now update their layout correctly after a DPI change 
+(dotnet/winforms #14454).
+
+**`System.Windows.Forms.ProgressBar`**
+* `ProgressBar` now applies a default color in Dark Mode to improve visual contrast
+(dotnet/winforms #14339).
+
+**`System.Windows.Forms.Clipboard`**
+* `GetText(TextDataFormat.Rtf)` now retrieves RTF data that does not include a null-terminating character, and restores the previous behavior (dotnet/winforms #14461).
+* `GetDataObject().GetImage()` now returns bitmap images correctly 
+(dotnet/winforms #14427).
+
+**`System.Windows.Forms.Control`**
+* `AnchorLayoutV2` now initializes deferred anchor information correctly when anchored controls are replaced while layout is suspended
+(dotnet/winforms #14505).
+
+**`System.Windows.Forms.CheckBox` and `System.Windows.Forms.RadioButton`**
+* `CheckBox` and `RadioButton` controls now return to their normal appearance when the `Appearance` property is changed in Dark Mode 
+(dotnet/winforms #14194).
+
+**`System.Windows.Forms.StatusStrip`**
+* `StatusStrip` now calculates its default padding and grip width consistently, preventing spring-enabled `ToolStripStatusLabel` controls from disappearing
+(dotnet/winforms #14068).
