What’s new

This release brings a redesigned Settings experience with tabbed navigation, a unified send flow with clearer payment options and Lightning support for more payment types, and new onboarding when you have no Lightning connections yet. Support and PIN flows are easier to follow, and we fixed several issues including payment precision, a settings-screen freeze, and stability when returning to Receive.
