[oslo] Feature freeze is apporching

Hi there,

Just a friendly reminder that oslo's feature freeze[1] will happen. Oslo observes a feature freeze that is earlier than other projects. And it's coming up soon. Aug. 15th is the Oslo feature freeze date for this cycle. That leaves about one week for features to be merged in Oslo libraries. After that, any features to be merged will require a feature freeze exception, which can be requested on the list. Feel free to ping us on IRC if you need code review.
