From the [WordPress 5.1.1 release post](https://wordpress.org/news/2019/03/wordpress-5-1-1-security-and-maintenance-release/),
this release contains bug fixes, enhancements, and security fixes. These changes
include:

 * A pair of security fixes that handle how comments are filtered and then stored
   in the database.
 * Hosts can now offer a button for their users to update PHP.
 * The recommended PHP version used by the “Update PHP” notice can now be filtered.
 * Several minor bug fixes.

For a full list of changes, please consult the [list of tickets on Trac](https://core.trac.wordpress.org/query?status=closed&resolution=fixed&milestone=5.1.1&order=priority).

Props to Simon Scannell of RIPS Technologies who discovered the security flaw independent
of some work that was being done by members of the core security team.
