MariaDB 10.0.18 Overview and Highlights

MariaDB 10.0.18 was recently released, and is available for download here:

https://downloads.mariadb.org/mariadb/10.0.18/

This is the ninth GA release of MariaDB 10.0, and 19th overall release of MariaDB 10.0.

There were no major functionality changes, but there were some general improvements, several security fixes, plus a 10.0.18 mysql_upgrade caution, and quite a few bug fixes, so let me cover what I feel are the main items of note:

  • Security Fixes: Fixes for the following security vulnerabilities:
  • InnoDB upgraded to 5.6.24
  • XtraDB upgraded to 5.6.23-72.1
  • Spider upgraded to 3.2.21
  • mroonga upgraded to 5.02
  • Performance Schema upgraded to 5.6.24
  • Connect upgraded to 1.03.0006
  • Deprecation Notice: As per the MariaDB Deprecation Policy, this will be the final release of MariaDB 5.5 for Fedora 19 “Schrödinger’s Cat”, Ubuntu 10.04 LTS “Lucid”, and Mint 9 LTS “Isadora”. When the next version of MariaDB 5.5 is released, repositories for these distributions will go away.
  • Important mysql_upgrade Caution: The mysql_upgrade in this version introduced a serious bug which affects mysql_upgrade. If already running a MariaDB 5.5.x version, then you can safely skip running mysql_upgrade. However, if migrating from MySQL to MariaDB 5.5, then note this bug. For this specific bug, the problem appears if the targeted databases include data structures such as views with binary or text blobs. The malfunction is in the REPAIR VIEW statement which the script calls.
    • The fix will appear in MariaDB 5.5.44, which will be available soon (MariaDB 5.5.44 includes all MySQL 5.5.44 fixes, so it will be available very shortly after MySQL 5.5.44 is released).

Given the security fixes, if you are running a prior version of 10.0, I would recommend upgrading. However, due to the mysql_upgrade bug in this version, I recommend upgrading to
10.0.19 instead (as it contains the fix for this bug).
