 ## Release Notes:
 
+- v4.1.1 - Bug fixes for multidimensional regression, reproducibility fixes for liblinear and libsvm, fixes for KMeans and KNN running with SecurityManager, and updated TF-Java to fix bugs in upstream TF.
 - v4.1.0 - Added TensorFlow training support, a BERT feature extractor, ExtraTrees, K-Means++, many linear model & CRF performance improvements, new tutorials on TF and document classification. Many bug fixes & documentation improvements.
 - v4.0.2 - Many bug fixes (CSVDataSource, JsonDataSource, RowProcessor, LibSVMTrainer, Evaluations, Regressor serialization). Improved javadoc and documentation. Added two new tutorials (columnar data and external models).
 - v4.0.1 - Bugfix for CSVReader to cope with blank lines, added IDXDataSource to allow loading of native MNIST format data.
