Technical notice⚠️ In the next release, we will stop publishing CatBoost artifacts for Python 2.7 & 3.5 versions. If you still need CatBoost built for 2.7 or 3.5 - you can build it from sources.
If you have any questions - contact us here, in telegram or via GitHub issues!😺

🚀🎇1.0.0😺🥳
It's not only CatBoost's 100₂ anniversary but also a first major release! We upgraded the major version because CatBoost looks solid: by the last four years, CatBoost began to play a crucial role in Yandex, CERN, and many other companies.

New paper: we tested how different ML methods perform on predicting administrative errors in US unemployment insurance data. Turns out: @CatBoostML is more accurate, along several measures, than every deep learning model tested. (open access for two weeks) dl.acm.org/doi/10.1145/34636…
