I received replacement 10-30 and 14-30 adapters, for the recall, on 23 Mar 2017 -- some months after the initial notification. According to the enclosed paperwork, here are the 5 parts subject to recall (note the old 14-50 was long ago recalled separately):
NEMA 6-50: 1016021-00-A and 1016021-00-B
NEMA 10-30: 1016174-00-B
NEMA 14-30: 1018243-00-A and 1018243-00-B
If they have a gray plastic cap (rather than black), they are the new versions.
