[oslo] Reminder: Feature Freeze is this Friday

This is your friendly neighborhood PTL reminding you that if you need a feature to merge in Oslo this cycle, it should be in by this Friday. We feature freeze earlier than other projects so they have a chance to make use of any features we add before their feature freeze. After Friday, any new features in Oslo will require an exception from me. I don't see much in the way of feature reviews open against Oslo right now (at least none that are mergeable), but if I missed anything let me know. Thanks. -Ben
