Typer 0.21.0 drops support for Python 3.8 ⚰️ This includes a lot of work from YuriiMotov to modernize the syntax for all the examples in the docs ✨ typer.tiangolo.com

And here's SQLModel 0.0.29, more bug fixes 🎄 sqlmodel.tiangolo.com

SQLModel 0.0.28, a small bug fix 🎁 sqlmodel.tiangolo.com

Pics from a keynote I gave at @es.pycon.org, in Spanish, in October 🇪🇸💃

FastAPI 0.127.0 raises a deprecation warning if you use pydantic.v1 🔊 Support for pydantic.v1 will be fully dropped next ☕️ You should (and probably are) using @pydantic.dev v2 ✨

Only supporting @pydantic.dev v2 in @fastapi.tiangolo.com will enable so many cool features and performance improvements, while solving bugs in edge cases. I'm excited. ⚡️

ty is awesome ✨ I'm amazed at Astral's technical excellence and developer experience focus. Ty is not only crazy fast, it improves what's possible with Python (check their Type System docs). And the editor support, chef kiss 🤩 docs.astral.sh/ty/ ty @crmarsh.com

I gave a keynote at PyCon Japan some months ago 🏯 First time I gave a talk that was live translated (by humans) to the audience 🎧️

Typer 0.20.1 🎁 With a bunch of bug fixes and improvements. 🚀 Special thanks to @oxykodit.bsky.social for all the help! 🙌 typer.tiangolo.com

Now I can finally use list[int], typing.Annotated, and friends, in the internals of FastAPI, so happy 🤩

Some pics from my keynote at @pycontw.bsky.social a couple of months ago 🐍

Dropping support for Python 3.8 in @fastapi.tiangolo.com will help with several things. And then dropping support for @pydantic.dev v1 right after will unlock a bunch of improvements that can be done only with Pydantic v2. 🤩

A couple of bug-fix releases, FastAPI 0.124.1 and 0.124.2 🐛 github.com/fastapi/fast...

The new frontend baseline template for your next app with @fastapi.tiangolo.com is looking so nice ✨ Another big frontend migration from alejsdev, thank you! 🙌

Some pics from my @europython.eu keynote earlier this year 😁🇪🇺🐍 I talked about the ideas behind @fastapi.tiangolo.com and friends, Typer, Asyncer, SQLModel... And how to apply those ideas to products as well, including a bit of how they are applied in FastAPI Cloud too.

Here's @savannah.dev's first feature in @fastapi.tiangolo.com! 🚀

Here's FastAPI 0.123.10 ☕️ A couple of bugs handled, confirmed, and fixed by YuriiMotov 🙌🐛 github.com/fastapi/fast...

Another FastAPI bug-fix release, 0.123.9 🐛 This fixes more edge cases around OpenAPI and OAuth2 scopes 🔒️ It required a considerable internal refactor, so now the code is more robust and less error-prone. 😎 github.com/fastapi/fast...

💅 we’re out here building the best Python cloud you’ve ever seen, y’all!

It's liveee! 🤩 The folks from @cultrepo.bsky.social made a mini documentary about @fastapi.tiangolo.com ! 🚀🎉 📺️ www.youtube.com/watch?v=mpR8...

Mooore releases! FastAPI 0.123.8 🥞 🐛 Fix a bug in the OpenAPI schema generated for security schemes using OAuth 2 scopes, when using different scopes at the router or path operation level github.com/fastapi/fast...

FastAPI will drop support for Python 3.8 in the next days 🔥

Now FastAPI 0.123.7 ☕️ 🐛 Fix corner cases in stringified annotations in Python 3.10+ (a.k.a. from __future__ import annotations)

This was a hard one ☕️ Now there are hyper-comprehensive tests for all the combinations and the implementation to ensure they are covered 😎

We added support for the pylock.toml standard to FastAPI Cloud (via uv, @nucleonjohn.bsky.social did it 🙌) just to be able to tag @snarky.ca ...and because *standards* too. But tagging Brett is important. 😎 fastapicloud.com/docs/builds-...

Today I'll break the record for releases in a day. 😎

Beyond a certain size of a project, ANY change can break someone's app, because the probability that someone is doing something strange increases. Granular releases help with that. 🌾

I'm trying to make a few @fastapi.tiangolo.com releases with bug fixes before dropping support for Python 3.8 and Pydantic v1, and soon also drop support for Python 3.9. 🔥

Tiny bug fix release, Asyncer 0.0.11 🐛 github.com/fastapi/asyn...

Here's a @fastapi.tiangolo.com bug fix release to start December. 🍫

This would be a good moment to join the FastAPI Cloud waiting list 🤫 fastapicloud.com

This was requested in @fastapi.tiangolo.com for a long while. 🎉 It required some thorough research to stay compliant with the specs, as there are a couple of nuances that not everyone is aware of: 401 errors MUST have a WWW-Authenticate header with a valid value. 🤓 Great job YuriiMotov! 🙌

Small refactor release, FastAPI 0.121.3 ☕️ github.com/fastapi/fast...

Quick bug fix release, FastAPI 0.121.2 🍰 🐛 Fix handling of JSON Schema attributes named "$ref" github.com/fastapi/fast...

A basic @fastapi.tiangolo.com app, just one command away. 🎁 First FastAPI thing from @savannah.dev ! 🙌 Also, @crmarsh.com 's uv is awesome, use it. 😎

Less typing when using @fastapi.tiangolo.com 🚀

This is heart warming 😊 www.herodevs.com/blog-posts/a...

Here's a smol bug-fix release for the weekend, FastAPI 0.121.1 🐛 luzzodev just fixed Depends(func, scope="function") when used in the router, at the top level. 😎 github.com/fastapi/fast...

I have the coolest team ever, for @fastapi.tiangolo.com and FastAPI Cloud 🤩 We had a great time together at an offsite in Seville last month. ...a sneak peek/pic below. (@marco.ooo, @nucleonjohn.bsky.social, @savannah.dev, @patrick.wtf, @oxykodit.bsky.social)

Here's FastAPI 0.121.0 🍰 In case you needed to exit early from dependencies with yield, you can now opt in with: Depends(some_func, scope="function") fastapi.tiangolo.com/tutorial/dep...

It's so cool to be able to have someone like Yurii constantly watching issues and discussions like a hawk. 🦅 This way, we can quickly discover important things and bugs happening on the repos, despite the continuous massive amounts of communications and questions. 🕵️🐛

I had a fun chat with @clytaemnestra.bsky.social at EuroPython 😁

Here's FastAPI 0.120.2 ☕️ Fixing a bug when generating schemas for multiple nested models 🐛 github.com/fastapi/fast...

All in Python, with Typer and Rich!

🔥 The most popular Python framework, with 4+ million downloads a day. Why did @fastapi.tiangolo.com grow so quickly? What’s next for it? And why FastAPI Cloud? I had the chance to chat with its creator, @tiangolo.com about all these and more. Full episode next week! www.youtube.com/watch?v=UpqT...

Here's @savannah.dev's first feature in Typer 😎 Suggest commands on error 🙋 Available in Typer 0.20.0 just released 🎉 Read the new docs: typer.tiangolo.com/tutorial/com...

Asyncer 0.0.10 with support for Python 3.14 🐍🔄 github.com/fastapi/asyn...

Quick fix release, 0.119.1 🍫 This fixes compatibility (warnings) with @pydantic.dev 2.12.1 on Python 3.14 🐍 Nothing changed for the final users, but still a lot of work underneath to get it done. 😅 Thanks @oxykodit.bsky.social! 🙌 github.com/fastapi/fast...

There's something satisfying in finishing the @es.pycon.org keynote, in Spain, about Python, @fastapi.tiangolo.com and friends, with this slide.

This is the most black magic I've done since adding support for @pydantic.dev v2 (or v1) to @fastapi.tiangolo.com... 🧙‍♂️ Now it has support for both Pydantic v2 AND v1 ✨ So much work just so you can migrate that old (or big) FastAPI app to Pydantic v2, please make it worth it, migrate to v2 ☕️
