New Board Chair Paul Sagan

You can find Governor Baker's press release regarding this appointment here.
Fascinatingly, what doesn't get mentioned is Mr. Sagan's role as Chair of the Massachusetts Business Leaders' Alliance for Charter Public Schools; you can see a sample of that work here. He also was (at some point) an advisor to MATCH charter schools (read to the bottom).

I don't think that there's much more to say here.
