-Version: 1.0.2
+Version: 1.0.3
 Authors@R: c(person("Peter", "Kharchenko", email = "[email protected]", role = c("aut")), person("Viktor", "Petukhov", email = "[email protected]", role = c("aut")), person("Dirk", "Eddelbuettel", email="[email protected]", role=c("ctb")), person("Evan", "Biederstedt", email = "[email protected]", role=c("cre", "aut")))
 Description: Implements methods to perform fast approximate K-nearest neighbor search on input matrix. Algorithm based on the 'N2' implementation of an approximate nearest neighbor search using hierarchical  Navigable Small World (NSW) graphs. The original algorithm is described in "Efficient and Robust Approximate Nearest Neighbor Search Using Hierarchical Navigable Small World Graphs", Y. Malkov and D. Yashunin, <doi:10.1109/TPAMI.2018.2889473>, <arXiv:1603.09320>.
