1.0.0rc1 (February 23, 2026)

We're ready! I'm thrilled to announce the first release candidate for Starlette 1.0.

Starlette was created in June 2018 by Tom Christie, and has been on ZeroVer for years. Today, it's downloaded almost 10 million times a day, serves as the foundation for FastAPI, and has inspired many other frameworks. In the age of AI, Starlette continues to play an important role as a dependency of the Python MCP SDK.

This release focuses on removing deprecated features that were marked for removal in 1.0.0, along with some last minute bug fixes. It's a release candidate, so we can gather feedback from the community before the final 1.0.0 release soon.

A huge thank you to all the contributors who have helped make Starlette what it is today. In particular, I'd like to recognize:

• Kim Christie - The original creator of Starlette, Uvicorn, and MkDocs, and the current maintainer of HTTPX. Kim's work helped lay the foundation for the modern async Python ecosystem.
• Adrian Garcia Badaracco - One of the smartest people I know, whom I have the pleasure of working with at Pydantic.
• Thomas Grainger - My async teacher, always ready to help with questions.
• Alex Grönholm - Another async mentor, always prompt to help with questions.
• Florimond Manca - Always present in the early days of both Starlette and Uvicorn, and helped a lot in the ecosystem.
• Amin Alaee - Contributed a lot with file-related PRs.
• Sebastián Ramírez - Maintains FastAPI upstream, and always in contact to help with upstream issues.
• Alex Oleshkevich - Helped a lot on templates and many discussions.
• abersheeran - My go-to person when I need help on many subjects.

I'd also like to thank my sponsors for their support. A special thanks to @​tiangolo, @​huggingface, and @​elevenlabs for their generous sponsorship, and to all my other sponsors:
