Release Announcement: Jubatus 0.9.4

[Kenichi Maehashi]

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/>.
