Release 3.2.1

[martin-springer]

Maintenance

• Migrated to pyproject.toml: Replaced setup.py/setup.cfg with pyproject.toml using setuptools as the build backend. (Domain change updates #488)
• Switched to setuptools-scm: Replaced versioneer with setuptools-scm for automatic version management from git tags. Removed legacy files: setup.py, setup.cfg, versioneer.py, MANIFEST.in, and rdtools/_version.py. (Domain change updates #488)
• Updated __init__.py: Now uses importlib.metadata for version retrieval instead of versioneer. (Domain change updates #488)
• Updated GitHub URLs: Migrated references from NREL/rdtools to NatLabRockies/rdtools and email addresses from @nrel.gov to @nlr.gov. (Change NREL to NLR #492)
• Adopted pixi: Introduced pixi for reproducible environment management, replacing requirements.txt, requirements-min.txt, and docs/notebook_requirements.txt with pixi environments and a lockfile. (Change NREL to NLR #492)
• Rewrote CI workflows: Updated pytest.yaml and nbval.yaml to use pixi via prefix-dev/setup-pixi; removed the requirements.yaml workflow. (Change NREL to NLR #492)
• Bumped minimum arch version from 5.0 to 5.6. (Change NREL to NLR #492)
• Added Python 3.14 to the test matrix and package classifiers. (Change NREL to NLR #492)
• Simplified pixi environments: core (bare), default (notebooks), dev (notebooks + test, alias for dev-py313), dev-py310–dev-py314 (full dev per Python version), and dev-min (minimum dependency versions). All shared environments pin Python 3.13. (Change NREL to NLR #492)
• Added composable pip extras: [notebooks], [test], [dev], [doc], and [all]. (Change NREL to NLR #492)
• Updated documentation: README, Sphinx index, developer notes, and example notebook setup cells updated for pixi and pip extras. (Change NREL to NLR #492)

Bug Fixes

• Fixed broken link to TrendAnalysis example in Sphinx index page. (Change NREL to NLR #492)

Requirements

• Added llvm-openmp as a platform-specific conda dependency for macOS (osx-64 and osx-arm64) to fix XGBoost installation issues — users no longer need to install libomp via Homebrew. (Adopt pixi for environment management and modernize CI #493)
• Bumped minimum xgboost from 1.6.0 to 1.7.0 to fix pkg_resources import error in environments without setuptools. (Adopt pixi for environment management and modernize CI #493)
• Bumped minimum pvlib from 0.12.0 to 0.13.1 to include the detect_clearsky() bug fix (pvlib GH2550). (Adopt pixi for environment management and modernize CI #493)
