+# monocle3 0.1.3
+
+### Changes
+* Added bootstrap bars to plot_percent_cells_positive().
+* Added a UMI cutoff for load_cellranger_data().
+* Added clear_cds_slots() to clear slots from a cds.
+* Added cell_stroke parameter to plot_cells.
+
+### Bug fixes
+* Fixed #154, which actually resulted from a problem in how ncenter was calculated for each partition.
+* Fixed an issue that prevents plotting cells by pseudotime when root_cells are passed to order_cells().
+* Fixed #167 - NAs from plot_genes_by_group.
