When this setting is set to "Block", iThemes Security will block brute force login attacks against XML-RPC as described by Sucuri in this blog post: https://blog.sucuri.net/2015/10/brute-force-amplification-attacks-against-wordpress-xmlrpc.html Enhancement: Updated text describing the XML-RPC setting in the WordPress Tweaks section to better explain what the setting is for and which setting is recommended.

Bug Fix: Modifications to the wp-config.php file added by W3 Total Cache now have their Windows-style newlines preserved when iThemes Security updates the file. 6.3.0 - 2017-07-06 - Chris Jean & Timothy Jacobs Important: The way that Hide Backend functions changes in this release. Previously, if your Hide Backend Login Slug was wplogin, going to example.com/wplogin would result in the URL remaining example.com/wplogin. The new implementation of this feature results in a redirect to a URL that looks as follows: example.com/wp-login.php?itsec-hb-token=wplogin. While this may not be desireable for some users, this change was necessary to fix longstanding compatibility issues with other plugins. Once you access the login page using the Login Slug page, a cookie is set with an expiration time of one hour. As long as the cookie remains, you can access example.com/wp-login.php without having to access the Hide Backend Login Slug first. If you wish to confirm that Hide Backend is working properly on your site, opening up a private browsing window is a quick way to test without having to log out and clear cookies.

This will not affect existing sites. Enhancement: Hide Backend functions purely in PHP code now rather than relying half on PHP code and half on .htaccess and nginx.conf modifications. This allows Hide Backend to function on web servers and server configurations that it was previously not compatible with. Misc: Updated or added phpDoc to many functions. Misc: Updated Disable File Locking description. 6.4.0 - 2017-07-24 - Chris Jean & Timothy Jacobs Enhancement: Replaced file locking with database locking. This method of locking is compatible with all systems as it does not require the ability to write files. It also allows for locking to work on sites that have multiple front-end servers with a shared database. Since file locking is no longer used, the Global Settings > Disable File Locking setting was removed. Enhancement: Add "Copy to Clipboard" functionality for server and wp-config rules. Bug Fix: Prevent 404s when following links in email notifications on a site with Hide Backend enabled. Bug Fix: Ensure uninstall process is not run when another version of iThemes Security is still active. Bug Fix: Fixed method of working around Hide Backend.

Bug Fix: Error when searching for modules preventing modules from appearing. Bug Fix: Use the wp_options table when acquiring locks in Multisite. Bug Fix: Prevent duplicate daily digest emails on sites with high load. Misc: Added Magic Links, a new Pro-only feature, to be activated by Security Check. Misc: Rearranged modules to be listed alphabetically. 6.6.1 - 2017-09-21 - Chris Jean & Timothy Jacobs Bug Fix: Fixed SQL query bug that resulted in the "Minutes to Remember Bad Login (check period)" setting being ignored.
