+# Tribuo v4.3.1 Release Notes
+
+Small patch release to bump some dependencies and pull in minor fixes. The most
+notable fix allows CART trees to generate pure nodes, which previously they had
+been prevented from doing. This will likely improve the classification tree
+performance both for single trees and when used in an ensemble like
+RandomForests.
+
+- FeatureHasher should have an option to not hash the values, and TokenPipeline should default to not hashing the values ([#309](https://github.com/oracle/tribuo/pull/309)).
+- Improving the documentation for loading multi-label data with CSVLoader ([#306](https://github.com/oracle/tribuo/pull/306)).
+- Allows Example.densify to add arbitrary features ([#304](https://github.com/oracle/tribuo/pull/304)). 
+- Adds accessors to ClassifierChainModel and IndependentMultiLabelModel so the individual models can be accessed ([#302](https://github.com/oracle/tribuo/pull/302)).
+- Allows CART trees to create pure leaves ([#303](https://github.com/oracle/tribuo/pull/303)).
+- Bumping jackson-core to 2.14.1, jackson-databind to 2.14.1, OpenCSV to 5.7.1 (pulling in the fixed commons-text 1.10.0).
