Yes - The F-35s software is still being worked on and improved. They probably still have some conservative profiles established in the software while they are going through shake down. The tests from earlier this year indicated that there is room for growth (they can raise limits\adjust the system to allow for more stressful maneuvers.)
Incremental changes as they go through the validation process.
Just to clarify,
The software in place set a profile that allowed for decent margin in departure testing among other things. This will have a significant impact on maneuvers typical in balls out testing. The results of the tests this year is that they can relax some of settings a bit.

test pilots say the aircraft can be cleared for greater agility as a growth option.
U.S. Air Force and
Lockheed Martin test pilots say the availability of potential margin for additional maneuverability is a testament to the aircrafts recently proven overall handling qualities and basic flying performance. The door is open to provide a little more maneuverability,
Work is underway as part of efforts to clear the final system development and demonstration (SDD) maneuvering envelopes on the way to initial operational capability (IOC).
When we did the first dogfight in January, they said, you have no limits, says Nelson. It was loads monitoring, so they could tell if we ever broke something. It was a confidence builder for the rest of the fleet because there is no real difference structurally between AF-2 and the rest of the airplanes.
The operational maneuver tests were conducted to see how it would look like against an F-16 in the airspace, says Col. Rod Trash Cregier, F-35 program director. It was an early look at any control laws that may need to be tweaked to enable it to fly better in future. You can definitely tweak itthats the option.
Pilots really like maneuverability, and the fact that the aircraft recovers so well from a departure allows us to say [to the designers of the flight control system laws], you dont have to clamp down so tight,
