are they still dropping ?
have you seen any of them drop ?
FYI the relevant drops are:
Assassin's Blade
Black Malice
Duskbringer
Face Smasher
Guillotine Axe
Night Reaver
Shadowfang
Witching Stave
Gloomshroud Armor
Mindthrust Bracers
Necrology Robes
PS. on a side note the Deathsworn Captain still spawns meaning you can get two chances at his drops in a single run as they also drop from the new bosses
