☑ Titanium grid fins for unlimited re-uses.
☑ New landing legs with the ability to be retracted by the ground crew instead of having to be removed after landing. These legs will also be black instead of white.
☑ Changes to the turbopumps to prevent turbine wheel microfractures. This was never considered a risk by SpaceX but NASA asked SpaceX to fix the issue and from all reports they have.
☑ Replace paint with thermal protection barrier coating for the purposes of re-use.
☑ Improved heat shielding around the engines to improve re-usability.
☑ The octaweb (structure that holds the engines) will be bolted instead of welded, to reduce time for inspection/repair/refurbishment and to allow easy change from F9 to FH side booster.
☑ The interstage will be black instead of white - likely unpainted carbon fiber (saves time and weight).
☑ Upgraded fairing, Fairing 2.0, which is very slightly larger and has changes to allow for recovery and re-use. It is also easier to make and lighter than the previous fairings.
☑ SpaceX's upgraded COPVs (dubbed COPV 2.0) will fly on Block V. This is an upgrade to further reduce the potential for an incident like Amos-6.
☑ Another improvement in thrust for the Merlin 1D engines (roughly 10%).
☑ The rocket will be man-rated, meaning it will be certified to carry crew. NASA has set the bar at 7 successful flights of the rocket for certification.
☑ Upgrades to active components such as valves, as well as many other parts to allow for many re-uses.
☑ Improved flight control, angle-of-attack, and control authority which should allow for landings with less fuel (and therefore the ability to land after lofting heavier payloads).
