• [Breaking] Bumped implicit from 0.4.4 to ^0.7.1
• [Breaking] Moved nmslib and lightfm to extras. Renamed nn extra to torch
• [Breaking] Improved TimeRangeSplitter interface: no need for pre-computing fold borders any more
• New metrics:MRR, F1Beta, MCC
• New splitters for cross-validation:RandomSplitter, LastNSplitter
• Significantly optimized inference speed for latent factors models (iALS, LightFM, PureSVD)
• Python 3.10 support 🎉
