MariaDB 5.5.44 released since Jun 11 but I never see it update in Custombuild 2.0. (Just check again today) Below is release notes :
MariaDB 5.5.44 is a maintenance release. It includes several bugfixes and updates, including from MySQL 5.5.44. Notable updates include:
XtraDB updated to 5.5.42-37.2
TokuDB updated to version 7.5.7
Client command line option --ssl-verify-server-cert (and MYSQL_OPT_SSL_VERIFY_SERVER_CERT option of the client API) when used together with --ssl will ensure that the established connection is SSL-encrypted and the MariaDB server has a valid certificate. This fixes CVE-2015-3152.
A full list of all changes is in the changelog.
Thanks, and enjoy MariaDB!
