Heads up, Hosts!
The WordPress 5.8.1 Security and Maintenance update has been released. WP 5.8.1 contains 60 bugfixes both in core and in the block editor, all of which remedy data, XSS and other vulnerabilities.
Because of this, the Hosting Team is recommending that all Hosts test and push this update through to customers and users as soon as possible.
A list of fixes and files changed can be located here.
As always, the PHP Test Runner and Reporter can be used by Hosts to report errors to the WordPress Organization. In addition, Hosts are welcome to comment in the #hosting-community Slack channel and create Trac tickets for any bugs or concerns found during testing and implementation.
Testing on the part of Hosts is incredibly valuable for the maintenance and improvement of the WordPress software. Thank you to all Hosts and contributors who participate in testing! You are appreciated!
