: One I can recall from The Fall of Reach is the explicit mention of the
: dropship containing the 75 Spartan recruits for the forest exercise being
: changed to an Albatross from a Pelican (presumably because we didn't know
: of any dropship other than a Pelican in Halo 1 and learned when the game
: came out that it wouldn't hold 75 kids. This was later reinforced in The
: Fall of Reach comic from Marvel.

: They corrected the date discrepancy in Fhahad's Slipspace paper (although
: they missed correcting his Spartan number).

: The other books have similar minor corrections, but I don't have an extensive
: list.

: I actually provided them some of the corrections from my own notes from the
: original novels.

They removed the mention of the Elites fought in orbit around Reach being humanity's (or the Spartans') first encounter with the species, IIRC.
