Mroonga 5.01 has been released!

Topics

  • Supported Percona Server on CentOS 6/7
  • [Experimental] Start to support MySQL 5.7

Supported utf8_unicode_520_ci and utf8mb4_unicode_520_ci

You can specify utf8_unicode_520_ci or utf8mb4_unicode_520_ci to COLLATION. But the feature depends on groonga-normalizer-mysql 1.0.9 (the latest version).

utf8_unicode_520_ci and utf8mb4_unicode_520_ci are the UCA 5.2.0 version of utf8_unicode_ci and utf8mb4_unicode_ci. utf8_unicode_520_ci and utf8mb4_unicode_520_ci are not supported in groonga-normalizer-mysql of 1.0.8 and earlier versions so they were replacing with the default normalizer (NormalizerAuto). Since the latest version, MySQL compatible normalizer (NormalizerMySQLUnicode520CI) is used so the behavior is close to MySQL.

Please update Mroonga carefully if you use utf8_unicode_520_ci or utf8mb4_unicode_520_ci, because the behavior changes at using COLLATION by such as the database reconstruction and column addition.

The following link will help you to specify COLLATION:

Supported Percona Server on CentOS 6/7

We support Percona Server that is a MySQL compatible database server. We provide Mroonga with Percona Server packages for CentOS 6 and 7. Please see documentation for how to install.

[Experimental] Start to support MySQL 5.7

We start to support MySQL 5.7 but it is not official support because MySQL 5.7 is development stage. It may include updated InnoDB FTS feature from MySQL 5.6. We are happy if you tell us the result of evaluation of Mroonga and InnoDB FTS.

We welcome your feedback!
