`langchain-core` and a few other packages under `libs/` build their PyPI
sdists without a LICENSE file, so downstream redistributors have to
supply their own copy (the conda-forge `langchain-core` feedstock, for
example, keeps a manual `recipe/LICENSE` as a workaround).
Packages like `langchain-classic` and `langchain-anthropic` already ship
the license correctly because they have a `LICENSE` file in the package
directory that hatchling picks up by default. This brings the remaining
packages in line with that pattern by copying the repo-root MIT
`LICENSE` (verified byte-identical to the existing
`libs/langchain/LICENSE`) into the four package directories that lacked
one:
- `langchain-core`
- `langchain-model-profiles`
- `langchain-tests` (standard-tests)
- `langchain-text-splitters`
No `pyproject.toml` or build-config changes were needed — hatchling
includes a root-level `LICENSE` in the sdist automatically once the file
exists. All other package dirs (both `langchain` packages and every
`libs/partners/*`) already have one and were left untouched.
Verified by building each sdist with `uv build --sdist` and confirming
the file is in the tarball:
- `langchain_core-1.5.3.tar.gz` → `langchain_core-1.5.3/LICENSE`
- `langchain_model_profiles-0.0.6.tar.gz` →
`langchain_model_profiles-0.0.6/LICENSE`
- `langchain_tests-1.1.9.tar.gz` → `langchain_tests-1.1.9/LICENSE`
- `langchain_text_splitters-1.1.2.tar.gz` →
`langchain_text_splitters-1.1.2/LICENSE`
## Release note
The PyPI sdists for `langchain-core`, `langchain-model-profiles`,
`langchain-tests`, and `langchain-text-splitters` now include the MIT
`LICENSE` file.
