 ### Version 1.1.0
 
-- Added `syndiffix.py` python wrapper for ML feature selection.
-- Lowered default thresholds for range and singularity nodes to 15 and 5.
+- Added Python wrapper for auto-detecting column types and main features for ML.
+- Lowered default thresholds for range and singularity nodes and raised default tree depth limit.
 - Improved clustering algorithm for main column.
 - Added `--output` (`-o`) CLI argument to directly save the CSV file to disk.
 - Added `--clustering-mainfeatures <features>` CLI argument to specify main column's ML features.
