+## 1.1 (Unreleased)
+
+This release adds functionality around identifying outliers.
+
+* the Statistex struct comes with more keys: `:lower_outlier_bound`, `:upper_outlier_bound` & `:outliers`,
+along with the new public functions `:outliers/2` and `:outlier_bounds/2`.
+* `statistics/2` now also accepts `exclude_outliers: true` to exclude the outliers from the calculation
+of statistics.
+* some functions have also been updated to accept more optional arguments such as `:sorted?` to avoid unnecessary extra work.
+
+Huge thanks for these changes go to [@NickNeck](https://github.com/NickNeck)!
