Release notes for 10.10.94

The 10.10.94 hotfix release merges two unrelated pull requests for bug fixes. The first, prevents draft emails from coming into a published state when changing settings (thanks to Niall O'Doherty for the fix). The second, fixes an issue with front-end sub-menus hiding pages when the parent page is excluded from the sub-menu (thanks to Vivien Wong for the fix).
