While we are not even up to the alpha release yet of Fedora 24, there’s a call to already push back the entire schedule by up to a few weeks.
The current schedule puts the alpha freeze / software string freeze / change checkpoint on 16 February, Fedora 24 Alpha on 1 March, Fedora 24 Beta on 12 April, and the final release on 17 May. However, a proposal being pushed to the Fedora Engineering and Steering Committee would end up pushing back all of the F24 milestones by a few weeks: up to three or four weeks.
