ContextualTabGroups have disappeared?

[lilhoser]

In the latest release, the contextual tab groups that previously worked have disappeared. The tabs that I assign to contextual groups do show, but the header and coloring do not. Has something changed?

[batzen]

Yes, the default for HideContextTabs changed.
From the changelog:

• RibbonTitleBar
  - Changed default HideContextTabs from false to true

[lilhoser]

Can you tell me how to add a RibbonTitleBar to a RibbonWindow? I don't see a code example

[batzen]

You don't have to explicitly add it.
You can get the current window's instance from Ribbon.TitleBar or from RibbonWindow.TitleBar.
