Release notes for LensKit 0.0.2

The Git changelog and the list of closed tickets and pull requests provide more information on what has happened, including bugs that have been fixed.

This release contains a number of API changes to make the API cleaner and easier to move forward.

• Renamed BuildContext to RatingBuildContext to allow for a future BasketBuildContext.

• Added support for excluded items to recommendation API.

• Added AbstractRatingRecommender helper class to make implementing rating recommenders easier.

• Removed the RecommenderService class and several related classes to clean up the API. Client code should directly request RatingRecommender or RatingPredictor instances, and modules should scope them and their dependencies appropriately to avoid duplicating recommender models.

API Compatibility Notes

• Code dependent on BuildContext or PackedBuildContext must be updated to use RatingBuildContext and PackedRatingBuildContext instead.

• Code implementing RatingRecommender must be updated to implement the new API. We recommend using AbstractRatingRecommender to help with this.

• All code must be updated to directly receive injected RatingRecommender and/or RatingPredictor instances (or providers thereof).
