I know that people have the custom (I don't know how universal it is), to keep a lot of the restrictions of the nine days until Chatzos on Yud Av, such as not eating meat or doing laundry.

This year Tishah B'Av falls out on Shaboss, which causes the fast to be postponed to Sunday (which is Yud). My question is do the above mentioned customs apply this year on Yud-Aleph or not at all?
