On April 22, the staff of the New York city Charter Revision Commission recommended that the charter be amended to provide for Ranked Choice Voting.  See the report here.  The part about election changes begins on page eight.

The staff didn’t recommend that ranked choice voting be used specifically for primaries, or for general elections, or both.  But it stresses the value of using ranked choice voting for primaries because it would eliminate the need for runoff primaries.  Thanks to Michael Drucker for the link.
