+## [0.3.0]
+This is the version used for presentation at SciPy 2019
+### Added
+- functionality in `utils.results_csv` that computes d prime and adds it
+  to the .csv, as well as accuracy across both target present and target
+  absent conditions (i.e. what most people would call just "accuracy")
+- single-source version
+- summary results files and files with paths to training/validation/test
+  data are part of repository

+### Changed

+  conditions (instead of always separating out target present and target
+  absent conditions into two lines)
