+## [v0.2.3] - 2021-01-13
+
+**Major** upgrades to EBM in this release. Automatic interaction detection is now
+included by default. This will increase accuracy substantially in most cases.
+Numerous optimizations to support this, especially around binary classification.
+Expect similar or slightly slower training times due to interactions.
+
+### Fixed
+- Automated interaction detection uses low-resolution binning
+  for both FAST and pairwise training.
+### Changed
+- EBM argument has been reduced from `outer_bags=16` to `outer_bags=8`.
+- EBM now includes interactions by default from `interactions=0` to `interactions=10`.
+- Algorithm `treeinterpreter` is now unstable due to upstream dependencies.
+- Automated interaction detection now operates from two-pass to one-pass.
+- Numeric approximations used in boosting (i.e. approx log / exp).
+- Some arguments have been re-ordered for EBM initialization.
