i think that the release list desperately needs an improvement.
the problem is simple: in the last year there have been so many shoujo - yaou - doujinshi - one shot and small chapter - releases that keeping track with new mangas has become totally impossible at least for me and for those like me that don't have much time.
the problem is worst thinking that most people usually like only few genres (for me, i like seinen and very few shounen, not other things).
now the genres division is inefficient, since there are too many mangas, most of which have been abandoned since long ago.. (i've lost days trying to search between "genres" for new series i could try cause trying to check the "new releases" gave me on 99% yaoi or ecchi or shoujo (things i didn't like) and it was so frustrating you can't imagine since most of the series where abandoned!).
so here is my suggestion:
you should insert in the "new releases page" a "genres" division, with a small icon appearing before the name of the series, and a possibility to choose only some "genres" to be shown. something like tokyotosho does.
an icon for shounen, an icon for shoujo, an icon for seinen and so on, and the possibility (clicking on them) to see only that kind of releases.
could you realize something like that?
