v0.4.0

v0.4.0 — Debug/console output is opt-in

Changed (behavior)

A plain init() no longer prints spans to the console. Previously console output was auto-enabled in any non-production environment, so notebooks/scripts/CLIs saw unrequested span dumps. Console output is now off unless you pass debug=True.

Migration

init(service="my-app", debug=True)  # restore console spans in local dev

Based on user feedback that debug-on-by-default was a papercut — the first thing a new user saw was noise they didn't ask for.
