There is performance improvements and fixed memory leak issue related to fulltext search. We recommend upgrading to Mroonga 3.11.

Supported ORDER BY optimization for INT,DATETIME and TIME column

In this release, ORDER BY optimization for INT,DATETIME and TIME column are supported.

There is a case that searching database by combination with fulltext search (MATCH AGAINST …) and other type of column causes performance penalty if many records matches by fulltext search.

This issue is fixed by supporting ORDER BY optimazation for above type of columns. It also supports 'BETWEEN'. Note that Groonga 3.1.1 is required.

Here is the install documentation for Fedora 20

Dropped Debian 6.0(squeeze) and Ubuntu 10.04(lucid) support

As Groonga dropped support for above release, it affects also Mroonga. See following blog entry why squeeze and lucid are dropped.
