I found an error in the DRAFT I-129F form already. If you look at instruction #10 (for Spousal K-3), it still says to include documents in instruction steps 3, 4, and 6 (omitting 5). However, due to the additional IMBRA instructions, these numbers should have changed to 5, 6, and 8 (omitting 7) respectively.
Not sure if this can be brought to USCIS's attention... I'd hate for them to release a final version just to recall it a few days (or weeks) later.
