Description
The minimum version of MySQL required to run WordPress has sat at 5.0 since 2011 (see [17523]).
MySQL 5.0 was initially made generally available in 2005 and reached its end of life (EOL) in January of 2012, making it unsupported and insecure for over 12 years. This is extremely old and this requirement is being raised.
Currently, only 0.4% of all WordPress sites are running either version 5.0 or 5.1 of MySQL.
Usage for MySQL 5.5 sits at just under 15%, making it the logical landing point. Of all sites running 5.5.x, 100% of them are running 5.5.5 or higher. utf8mb4
support was introduced in 5.5.3, and InnoDB
was made the default storage engine over MyISAM
in 5.5.5, making it worthwhile to use the 5.5.5 point release instead of any 5.5.x version (utf8mb4
is the preferred default character set).
Raises the minimum version of MySQL required to run WordPress to 5.5.5.
