Given the previous Galileo launch expended the booster (B1060), I have a strong feeling another booster will be expended for this launch too.

Seeing as this launch is only 2 million euros cheaper, it seems like a safe bet.

Still targeting September.

To this date, the Galileo constellation has 30 First Generation satellites in orbit and an additional eight are ready to be launched, two in September this year and six more starting in 2025. Second Generation launches will begin before the end of this decade.

If I were to guess, a launch vehicle change.

I think its more likely they will try to land the booster on the dronship!

That was my initial guess when I saw the phrase "interesting changes".

But if my guess is right, then the Galileo sats may be placed into an elliptical orbit, them having to circularize that orbit afterwards. That's performance penalty from the fuel reserves after MECO.
i dont think galileo has apogee kick motors and so has to be placed directly into MEO
if it can launch them w booster reusable odds are it cant be put in a very eliptical orbit

I was using logic based on the GPS-III launches when the first launch expended the booster and inserted the satellite into an elliptical orbit with the perigee at 1,200 kilometers. When SpaceX began recovering the booster starting with GPS-III 3, the perigee was 800 kilometers lower (400 kilometers).
GPS-3 has an apogee propulsion system, Galileo does not have one, so this is not an option here.

If I remember correctly, a Galileo FOC satellite have 8(?) MOOG 1N thrusters and about 70 kg of fuel.
That is plenty for maneuvers and a very long satellite life, but not enough to circularize a transfer orbit.
