3.1.0: 2013-11-29
-----------------

Improvements
============

  * Reduced build failure by automatically Groonga
    build. [Reported by SHIMADA Koji]

  * Added groonga-database-inspect command that inspects
    passed database. [Suggested by Genki Takiuchi]
  * Groonga::Database#tables ignores missing objects rather
    than raising an exception. Because the method is
    interested in only existing tables.

Fixes
=====

  * Fixed a bug that Groonga::Expression#parse doesn’t
    accept all mode and operators.
