Joseph K. Bradley commented on SPARK-9671:
------------------------------------------
Non-breaking changes to behavior:
* RegressionMetrics.explainedVariance returns different value. This was
arguably a bug fix and does not break APIs, but it does change behavior.
[SPARK-9005]
* NaiveBayesModel.labels will now be in sorted order. That will not affect
predictions, but will affect the order of model data in labels, pi, and theta.
[SPARK-8600]
