The 2015 version of the paper was removed for revision. It was revised and the current revision (Dec 2016) still has the same position on vegetarian diets.

>POSITION STATEMENT
It is the position of the Academy of Nutrition
and Dietetics that appropriately planned
vegetarian, including vegan, diets are
healthful, nutritionally adequate, and may
provide health benefits in the prevention
and treatment of certain diseases. These
diets are appropriate for all stages of the life
cycle, including pregnancy, lactation, infancy,
childhood, adolescence, older adulthood,
and for athletes. Plant-based diets are more
environmentally sustainable than diets rich
in animal products because they use fewer
natural resources and are associated with
much less environmental damage.
And it was never actually a big deal in the first place, because they have maintained more-or-less the same position for several decades, and the removal didn't actually change their position in a significant way.

>Following the release of the “Vegetarian Diets” position paper, the Academy Positions Committee received correspondence from respected experts in the area of vegetarian nutrition, including Academy members, expressing concern about what they cited as inaccuracies in the paper. Upon receipt of the memoranda, the APC sent the paper out for a secondary external blind, unbiased review. Based on the result of these reviews, as well as the received correspondence from experts in the field, the APC voted to remove the paper from the Journal with the goal to revise and publish at a future date. Until then, individuals should refer to the “Vegetarian Diets” position paper published in the July 2009 Journal (Volume 109, Issue 7, pages 1266-1282).
This is the 2009 version:
