FastAPI 0.141.1

OK FASTAPI 0.141.1 JUST DROPPED ☕️ And it's a quick follow-up to yesterday's 0.141.0, because the team saw a gap and closed it FAST period.

The Big Fix: app.frontend() Gets Its Wings

Background tasks and headers from dependencies were getting dropped inside app.frontend() period. Not anymore. PR #16105 by Tiangolo himself patches the whole flow so your dependency-injected headers and background jobs actually survive the frontend route handler period.

FASTAPI_ENV Is Now Documented

You've been setting FASTAPI_ENV in your terminal for months without docs period. The CLI guide finally covers it — what it does, when to set it, why your fastapi dev workflow cares period. Documentation gap: closed period.

Should You Upgrade?

If you're on 0.141.0 and use app.frontend() with dependencies — yes, upgrade NOW period. If you're on anything older, this patch release is tiny, safe, and worth grabbing on your next deploy period.

pip install --upgrade fastapi and move on with your life 🔗
