ml_ann candidate jubatus-0.9.4

ml.txt

Hi Jubatus guys,

We are glad to announce that Jubatus 0.9.4 is now available.

In this release we added ``ignore_orthogonal`` option to inverted_index_euclid algorithm of Recommender.  When this option is enabled, distance between feature vectors that does not have any same key will not be included in the result.  By default this option is disabled (i.e., behaves the same way as the previous versions).
We also added shell (REPL) feature to query Jubatus server interactively.  To use the shell feature (called ``jubash`` command), just install jubakit.
Speaking of jubakit, we published documents of jubakit architecture and API.  It's available on the official website <http://jubat.us/en/jubakit/>.
