With pydantic >= 2.12.0, just test-all → all pass, but we get some warnings:

Not clear how I even end up on line 48:

$ uv pip list | grep pydantic
pydantic           2.12.3
pydantic-core      2.41.4
$ uv run python -c "import pydantic; print(pydantic.VERSION.startswith('1.'))"
False

[daaain]

Thanks a lot for these investigations @cboos, seems upgrading pydantic and anthropic makes the library pass the tests for all Python versions between 3.10-3.14 on both Linux and Windows CI VMs.

Actually, I decided to bump all libraries, see PR: #40

[cboos]

Note that it no longer works "out of the box" on Windows, due to "jiter" needing cargo to build:

  help: `jiter` (v0.10.0) was included because `claude-code-log` (v0.8.0) depends on `anthropic` (v0.72.0) which
        depends on `jiter`

I suppose if I do a regular rust/cargo install this will work... Also, in a few days, the prebuild binary wheel may become available.

[daaain]

Oh, that's annoying! I didn't want to break it for you @cboos (and everyone else on Windows), this makes me think of 2 things:

1. Can we set up a post-install / sync step with uv somehow and install it? Though I guess maybe installing Rust + Cargo in the background might be a bit too much – maybe downgrading anthropic to whichever version doesn't need that breaking jiter would be a simpler fix?
2. Can we add a test so that issues like this get caught in CI? Ie actually trying to run the library? Oh, maybe the issue is that in CI we're not installing dev packages? But we must, to be able to run tests, I'm really confused how this hasn't got caught... Waaait, do you have win_amd64?
