- Removes Codespell from deps, docs, and `Makefile`s
- Python version requirements in all `pyproject.toml` files now use the
`~=` (compatible release) specifier
- All dependency groups and main dependencies now use explicit lower and
upper bounds, reducing potential for breaking changes
Update `langchain-core` dependency min from `>=0.3.63` to `>=0.3.75`.
### Motivation
- We located the `langchain-core` package locally in the monorepo and
need to align `langchain-tests` with the new minimum version.
### Overview
Preparing the `1.0.0a1` release of `langchain-tests` to align with
`langchain-core` version `1.0.0a1`.
### Changes
- Bump package version to `1.0.0a1`
- Relax `langchain-core` requirement from `<1.0.0,>=0.3.63` to
`<2.0.0,>=0.3.63`
### Motivation
All main LangChain packages are now publishing `1.0.0a` prereleases.
`langchain-tests` needs a matching prerelease so downstreams can install
tests alongside the 1.0 series without conflicts.
### Tests
- Verified installation and tests against both `0.3.75` and `1.0.0a1`.
Follow up to https://github.com/langchain-ai/langsmith-sdk/pull/1696,
I've bumped the `langsmith` version where applicable in `uv.lock`.
Type checking problems here because deps have been updated in
`pyproject.toml` and `uv lock` hasn't been run - we should enforce that
in the future - goes with the other dependabot todos :).
Generally, this PR is CI performance focused + aims to clean up some
dependencies at the same time.
1. Unpins upper bounds for `numpy` in all `pyproject.toml` files where
`numpy` is specified
2. Requires `numpy >= 2.1.0` for Python 3.13 and `numpy > v1.26.0` for
Python 3.12, plus a `numpy` min version bump for `chroma`
3. Speeds up CI by minutes - linting on Python 3.13, installing `numpy <
2.1.0` was taking [~3
minutes](https://github.com/langchain-ai/langchain/actions/runs/14316342925/job/40123305868?pr=30713),
now the entire env setup takes a few seconds
4. Deleted the `numpy` test dependency from partners where that was not
used, specifically `huggingface`, `voyageai`, `xai`, and `nomic`.
It's a bit unfortunate that `langchain-community` depends on `numpy`, we
might want to try to fix that in the future...
