+### Deprecations
+
+ - **MLlib**

+
+### Changes of behavior
+
+ - **MLlib**

+ - **SparkR**
+ - SPARK-19291: This added log-likelihood for SparkR Gaussian Mixture Models, but doing so introduced a SparkR model persistence incompatibility: Gaussian Mixture Models saved from SparkR 2.1 may not be loaded into SparkR 2.2. We plan to put in place backwards compatibility guarantees for SparkR in the future.
