v2.6.0

Repository: microsoft/FLAML

Tag: v2.6.0

Published: 2026-04-28T02:02:26Z

Prerelease: no

Release notes: This release improves compatibility with the latest ecosystem packages, including scikit-learn 1.7+, Transformers 4.26+/5.0+, pandas 3.0, and recent setuptools changes. It strengthens packaging by unblocking editable installs and migrating metadata to PEP 621, fixes CatBoost and Optuna-related test issues, and adds timestamp generation for time series predictions without test data. It also includes website dependency updates, CI/deployment maintenance, and documentation updates for LightGBM quantile regression and supported Python versions.
