Release LIB 2019.2.603 (06/03/2019)
When the IsHidden property of a RadPane within a ToolWindow is set to True and then to false in quick succession, the ToolWindow is not shown. 

As a workaround, you can disable the animation of the ToolWindow:
<Style TargetType="telerik:ToolWindow">
<Setter Property="telerik:AnimationManager.IsAnimationEnabled" Value="False" />
</Style>

The above style need to be placed in the resources of the App.xaml in order to take effect on the ToolWindows, since they are displayed in a separated visual tree.

Release LIB 2019.1.422 (04/22/2019)

When the RadDocking Items are reordered during runtime and new RadSplitContainers/RadPaneGroups are generated, the save/load behavior is sometimes incorrect.

Release LIB 2019.1.422 (04/22/2019)

Dynamically adding RadPane to PaneGroup, the header of the pane does not appear on the second added pane.

To workaround this the OnApplyTemplate() method can be called after the RadPane is added to the RadPaneGroup.

The close button in the document host is not higlighted (hovered-button-state-doc-host.png) as opposed to panes outside the DocumentHost area (hovered-button-state.png).

The workaround is to update the MouseOver visual state of the RadButtonDocumentCloseControlTemplate:

             <ControlTemplate x:Key="RadButtonDocumentCloseControlTemplate" TargetType="telerik:RadButton">
                <Grid x:Name="LayoutRoot" Background="Transparent" Width="18" Height="18">

workaround:
add the following visual state to the DocumentHostTemplate of the RadPaneGroup:

<VisualStateManager.VisualStateGroups>
    <VisualStateGroup x:Name="DropDownDisplayStates">
        <VisualState x:Name="DropDownButtonCollapsed" />
        <VisualState x:Name="DropDownButtonVisible">
            <Storyboard>
                <ObjectAnimationUsingKeyFrames Storyboard.TargetName="DropDownButtonElement" Storyboard.TargetProperty="Visibility">
                    <DiscreteObjectKeyFrame KeyTime="0">
                        <DiscreteObjectKeyFrame.Value>
                            <Visibility>Visible</Visibility>
                        </DiscreteObjectKeyFrame.Value>
                    </DiscreteObjectKeyFrame>
                </ObjectAnimationUsingKeyFrames>
            </Storyboard>
        </VisualState>
    </VisualStateGroup>
</VisualStateManager.VisualStateGroups>

and remove the trigger targeting the drop down button.
