0.7 - add batch index creation 'treeBatch', 'forestBatch', 'dataBatch' and corresponding unit tests (#5) 0.6 - add 'knnPQ' based on 'heaps', to be confirmed how efficient it is 0.5.1 - no need for 'microlens' and 'hspec' in the library 0.5 - fixed intermittent bug in 'knn', originally due to messing up the order of 'take' and 'sort'. 0.4 - add function to compute the forest construction parameters from the dataset dimensions (rpTreeCfg) - add type parameter to RPTree to label tree branching points 0.3.6 - relax lower dependency bounds to ensure it builds with GHC 8.6.5 (== stackage lts 14.27) as well 0.2 - fix 'candidates' such that 'knn' now does the right thing - now 'knn' accepts a distance function as parameter as well - add I/O functionality - some time benchmarks
