From the presser around the the 21 minute mark, from Dan Hartman, There were major modifications to the Dragon between SpaceX 3 and SpaceX 4
Note than Hans walked that statement back later in the Q&A. Most of the modifications were payload-related, major to NASA but not "major" from SpaceX perspective.

Yes, he specified hardware upgrades on the avionics side and some hardware was moved from the pressure vessel to to outside, he categorized them as refinments and improvements. Not grand changes

Interesting that most of these are "range" rules and not related to the rocket itself.

Even with lower pressure stimulating rain, during the day convection is always adding to precipitation and by 2AM local time, that effect is gone. That's the only aspect giving today launch a shot.
KCOF TAF decode for launch window:
BECMG 2003/2004 05010KT 8000 -RA BKN030 OVC100 QNH2991INS
Becoming around 11PM-midnight local time
Winds 050@10 knots
Light rain
Broken 3000
Overcast 10000
Would a solid overcast @ 10 thousand feet or light rain be a problem ?
Both don't sound bad even for a light cessna to fly IFR (into the clouds).
NASA mission gets lots of NASA rules. I wouldn't be surprised if NASA doesn't allow CRS launches unless the board is all green, regardless of F9R being able to take it anyhow.
