# Changes v0.3

- Pinned Python package versions for Python 3.9/HPC compatibility.
- Updated `scripts/setup_env_login.sh` to unset compiler variables (`CC`, `CXX`, `FC`, `F77`, `F90`) because some HPC login environments export Intel `icc`, causing pandas source-build metadata generation to fail.
- Added `PIP_PREFER_BINARY=1` and `--prefer-binary` to reduce source builds.
