Pope Francis' 12-year papacy was dedicated to highlighting equality in the Catholic Church and informing on the state of climate change in the world.

The leader of the world’s 1 billion Roman Catholics addressed past scandals and embraced migrants, the poor and gay and lesbian faithful. Some wished he’d gone further.

A new pope does not swoop in and openly set about undoing the legacy of another. But a lot can change as far as style, emphasis, guidance and law.
