Spark R Interface

[Muttineni, Vinay]

Hi All,
Any news/updates on the Spark R interface?
I see from here 
(http://mail-archives.apache.org/mod_mbox/spark-user/201401.mbox/%3CCAGiTW48+otjXNgTJ=twg6fangkg-nu4bg31pxnmf7hlzvez...@mail.gmail.com%3E
 ) that an alpha version was to be released in January?
Thanks
Vinay
