if you take a look at Monzo’s mentions on Twitter after each release, you’ll see a lot of people sharing these notes. That’s marketing which = growth which = funding which = more developers to add features to the app.
And you’re right, there haven’t been any major releases in a while because the team’s been building the current accounts.
