What happened to SharePoint workspaces in SharePoint 2013

SharePoint workspaces is depreciaded but not Dead! You can Continue using it to sync SharePoint libraries and lists, including content hosted on SharePoint 2013 servers.

SharePoint 2013 sites don't provide direct access to SharePoint Workspace. There's no Site Actions menu, or Sync to SharePoint Workspace buttons on the ribbon. As a result, to create a SharePoint workspace from one of these sites, you must start in the SharePoint Workspace Launchbar, and directly reference the URL of the document library.

Additionally, because of a design change in SharePoint Server 2013 libraries, you must also install a SharePoint Workspace 2010 Update in order to sync these libraries in a SharePoint workspace.
