Yes still, though it was never mainstream. Even in Abelisaurus' original description, it was said to be closest to Ceratosaurus, Piatnitzkysaurus, Indosaurus and Indosuchus. Xenotarsosaurus was described as an abelisaurid (along with Abelisaurus and Carnotaurus) with Similarily, Carnotaurus was described as being closest to other abelisaurids (Abelisaurus, Xenotarsosaurus, Indosuchus), Noasaurus and Ceratosaurus. I actually can't recall anyone else who's suggested abelisaurids are closest to megalosaurids/torvosaurids, though relations to carcharodontosaurids and spinosaurids have been suggested.

Correcting a few characters...
"1 Is not totally clear in *Confuciusornis*."
It has the derived condition (25-30%) (Chiappe et al., 1999).
"15 *Archaeopteryx* has the famous constriction, but does someone know about,
Sinornis has very poorly preserved crania, but Cathayornis and the Spanish nestling have constricted roots.
"16 In *Yandangornis* the entire fused metatarsus is narrowed in the middle
and more proximally. Therefore I gave it 1, even though mt III is expanded
at its proximal end. Entire foot of Pygostylia coded after a very good photo
*Confuciusornis* (I haven't had a good look at a real specimen for months,
but that will come)."
I disagree. Yandangornis and Confuciusornis have broad proximal mtIII's and their metatarsi are not especially narrow proximally, even if that were the same character.
I also corrected characters 13 and 14 for ornithomimosaurs.
And the result is.....
160 MPT's of 78 steps each.
Yandangornis adds no data to the tree (so was deleted to minimize MPT's), but clades somewhere in the (Nomingia, Caenagnathidae ... Pygostylia) clade.
* CBL basically is the same as FABL
What do these abbreviations mean?
Crown basal length and fore aft basal length. Pretty much the mesiodistal length of the base of the tooth crown.
