+there seems a huge inefficiency in RailsDataExplorer#build_exploration_from_data_series_specs
+where we iterate over the entire data collection for every exploration.
+
+
+### 0.2.3
+
+* Don't show all explorations by default. Takes too long when having 100
+  explorations to render. Instead show univariate explorations by default
+  and bivariate explorations on demand.

 ### 0.2.2
 
 * Fixed file inclusion bug that prevented loading of Gem
