Only slightly. The enanthiornithes are now considered as being a higher
rank than ordinal. Also, most current cladograms show the
hesperonthiforms and relatives clearly outside of the enantiornithines.
[I doubt many peopel would still use "Odontognathae" as the name for
this group, however].
The peace of God be with you.
