Security and Maintenance Release from WordPress as Version 5.1.1

There is a new WordPress version 5.1.1 available for community.  This security and maintenance release introduces 10 fixes and enhancements, including changes designed to help hosts prepare users for the minimum PHP version bump coming in 5.2.

Highlights of this release include:

  • 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.
  • A pair of security fixes that handle how comments are filtered and then stored in the database. With a maliciously crafted comment, a WordPress post was vulnerable to cross-site scripting.
  • Several minor bug fixes.

WordPress 5.1.1 was a short-cycle maintenance release. Version 5.1.2 is expected to follow a similar two week release cadence.

You can download WordPress 5.1.1 or visit Dashboard → Updates and click Update Now. Sites that support automatic background updates have already started to update automatically.
