72 Release Notes


Upgrade blockers New features New Standardized Hooks In cPanel & WHM version 72, we added a Standardized Hook that triggers events before and after the installation or changes to SSL certificates via WHM’s Install an SSL Certificate on a Domain interface (WHM >> Home >> SSL/TLS >> Install an SSL Certificate on a Domain) or WHM API 1’s installssl function.

We also added a separate Standardized Hook for AutoSSL certificate installation.

Enable strict SSH host key checking In cPanel & WHM version 72, we added the Enable strict SSH host key checking option to the Security tab in WHM’s Tweak Settings interface (WHM >> Home >> Server Configuration >> Tweak Settings). This setting configures the server to require that the server verifies the host key of remote systems for outgoing SSH connections, such as rsync and SFTP backup, Transfer Tool, and Remote MySQL connections. This will help defend the server against main-in-the-middle (MITM) attacks.

For more information about this setting, read our Tweak Settings documentation.

New Gitâ„¢ Version Control feature cPanel & WHM version 72 introduces cPanel’s Git Version Control interface (cPanel >> Home >> Files >> Gitâ„¢ Version Control). This interface allows cPanel users to easily create and manage Git repositories. We disable this feature by default.

We ship this feature with Git’s Gitweb interface. Gitweb allows you to browse your repositories, view file contents, and review log, commit, and other information. For more information, read our Gitweb documentation. This feature includes restrictions on cPanel-hosted repositories and updates to Git’s default configuration. For more information and troubleshooting steps, read our Guide to Git documentation.

Added Contact Information to Feature Manager We added the Contact Information feature to WHM’s Feature Manager interface (WHM >> Home >> Packages >> Feature Manager) in cPanel & WHM versions 72 and 70. This feature allows hosting providers to control whether their users can access cPanel’s Contact Information interface (cPanel >> Home >> Preferences >> Contact Information).

The in-browser terminal application cPanel & WHM’s new in-browser terminal application provides direct command-line access within a cPanel & WHM session. This faster and easier successor replaces the Java-powered SSHTerm application that we removed in cPanel & WHM version 11.50.

WHM users can access this feature in WHM’s Terminal interface (WHM >> Home >> Server Configuration >> Terminal). cPanel users can access this feature in cPanel’s Terminal interface (cPanel >> Home >> Advanced >> Terminal). Server administrators can enable the terminal application for cPanel users with the SSH Access & Terminal setting in WHM’s Feature Manager interface (WHM >> Home >> Packages >> Feature Manager). Server administrators can create the /var/cpanel/disable_whm_terminal_ui touch file to disable the terminal application for WHM users. This includes both resellers with root access and the root user. The system does not create this file by default. Updated features Site software interface updates In cPanel & WHM version 72, we added a tabbed layout to cPanel’s Site Software interface (cPanel >> Home >> Software >> Site Software). Users who navigate to this interface will notice a more streamlined experience.

The File and Directory Restoration interface (formerly File Restoration) We added functionality to the File Restoration interface in cPanel & WHM so that users can restore directories as well as files from their backups. We updated the interface’s strings and renamed the interface File and Directory Restoration to reflect this change.

WHM users can restore files and directories for cPanel user accounts through the File and Directory Restoration interface (WHM >> Home >> Backup >> File and Directory Restoration). cPanel users can restore individual files through the File and Directory Restoration interface (cPanel >> Home >> Files >> File and Directory Restoration). Note:

For these restoration features to work appropriately in cPanel & WHM, system administrators must enable account file backups through WHM’s Backup Configuration interface (WHM >> Home >> Backup >> Backup Configuration).

Free unused metadata table space with the backups_create_metadata script We added the new argument –vacuum to the backups_create_metadata script. The –vacuum argument defragments the metadata SQLite database and frees unused space. Use this argument to free space if your metadata SQLite database holds a large amount of data. For more information, read the The backups_create_metadata Script documentation.

Updated PHP-FPM conversion look and feel in WHM’s MultiPHP Manager interface WHM’s MultiPHP Manager interface (WHM >> Home >> Software >> MultiPHP Manager) now indicates whether the system’s process to convert all of WHM’s accounts to use PHP-FPM is in progress.

Graceful restarts for PHP-FPM In cPanel & WHM version 72, we added the ability to restart PHP-FPM without service interruptions to clients that request PHP resources. During the PHP-FPM graceful restart, the system stops and restarts the PHP-FPM pool processes. As a result, the system temporarily holds the Apache process requests. When the PHP-FPM pool processes begin again, Apache passes the queued process requests on to the PHP-FPM pool processes and the workflow continues as normal.

Updated phpMyAdmin version In cPanel & WHM version 66 and later, we updated the version of phpMyAdmin that the system provides from 4.7.3 to 4.7.7. For more information about this phpMyAdmin version, read phpMyAdmin’s version 4.7.7 Release Notes documentation.

For more information about previous major versions of phpMyAdmin, read the following documents:

This setting specifies the number of emails sent by any email account in one hour that will cause the system to send an alert notification. In earlier versions, we configured this setting to a value of 500.

We also added the Monitor the number of unique recipients per hour to detect potential spammers. option, which allows you to enable or disable the check for the above option.
