The problem with httpx as a dependency is that it's currently working towards a 1.0 release which will be full of breaking changes.
The httpx2 project is essentially a fork that promises not to break the existing API, which makes it a more stable dependency to build against.
I wrote a pretty long comment about my concerns for the breaking 1.0 version last year - https://github.com/encode/httpx/discussions/3344#discussionc... - in that comment I recommended the HTTPX project release their 1.0 as a package called httpx2 instead, but a year later we now have an httpx2 (released by a different maintainer) that keeps the old API.
HTTPX stable hasn't had a release since December 2024, but there have been two dev releases of the 1.0 branch this month (after a gap since September 2025.)
Unfortunately that 1.0 work is happening in a private repository.

That’s even more reason to consider it non-viable.
There is no reason to encourage or support this type of behavior in a project. It is their right to do with it as they please, but I’m not interested in a project that functions like this. The forks are continuing to operate like true community projects.
people think other people are 'toxic' for the silliest of things most times; and this person is saying some maintainer is toxic to put it out there but provides no information as to why.. so i figured my context is as good as theirs
We started this fork because there was no activity on HTTPX, a very popular Python HTTP library.
A few weeks later, Pydantic started their own fork called HTTPX2. We decided to embrace this and support HTTPX2. We're upstreaming our fixes to HTTPX2 and in our opinion it should be the "blessed" fork. Pydantic can make this more successful than we ever can.

I mean, obviously Python 2.7 is newer than Python 3.1
I remember swearing I would never migrate to python3 but here we are, I migrated without even feeling it or realizing when (But I do remember django played a big role).
There are a lot of large projects where X.1 is newer than Y.0. You release a new major version for breaking changes, but you backport security changes to previous major releases as well.
Minors and hotfixes allow you to release a new version for an older release (like if you released 3.7 but you found a bug present in 3.4, you can release 3.4.1 which would be newer than 3.7), making it possible to have multiple supported versions at the same time.
The requests packages fundamental API is good enough and is now maintained by the PSF. I don't understand why OpenAI and Anthropic don't just throw some $$$ to the PSF for focused improvements and expansion of it.
The maintainers of requests have made it pretty clear that they consider that package feature complete, and have not showed interest in adding native async support to the core.

The httpx maintainer closed off access to issues and discussions on the repo, has been ignoring PRs, and hasn’t updated it in a half a year.
I don’t think there is any reason to consider httpx as a viable project any more. The Pydantic httpx fork has taken its place.

They also effectively killed off MkDocs: https://github.com/mkdocs/mkdocs/discussions/3677

Thanks for all your support!

But seriously, migrating between different libs should be ~free for both Anthropic and OpenAI.
wtf is going on

Happens with the Linux kernel as well.

You shouldn’t assume anything about relative date of 2.7 and 3.1.
But what are the upsides of this change?

Not that there is anything wrong with QUIC, at least its built by someone who knows what they are doing, unlike HTTP2
