 Please see the [MLlib Dependencies guide](mllib-guide.html#Dependencies) for more info.
 
 Spark ML also depends upon Spark SQL, but the relevant parts of Spark SQL do not bring additional dependencies.

-**Development plan**
-
-If all goes well, `spark.ml` will become the primary ML package at the time of the Spark 1.3 release.  Initially, simple wrappers will be used to port algorithms to `spark.ml`, but eventually, code will be moved to `spark.ml` and `spark.mllib` will be deprecated.
-
-**Advice to developers**
-
-During the next development cycle, new algorithms should be contributed to `spark.mllib`, but we welcome patches sent to either package.  If an algorithm is best expressed using the new API (e.g., feature transformers), we may ask for developers to use the new `spark.ml` API.
-Wrappers for old and new algorithms can be contributed to `spark.ml`.
-
-Users will be able to use algorithms from either of the two packages.  The main difficulty will be the differences in APIs between the two packages.
