[*] bug resolved and functionality improved


10.4.4

The following aggregated list contains changes that were introduced in 10.4.0 - 10.4.4 versions.

Parallels Plesk Panel 10.4.4

  1. [+]  Customizable PHP configuration. PHP settings are exposed to the Panel GUI and both administrators and resellers (if allowed) can adjust them individually for each hosting plan or subscription. Moreover, customers (if allowed) can adjust their PHP settings and preset them individually for each of their websites and subdomains. Supported settings include 16 common tunable parameters for performance, security, debugging, and also a free-text field for even more flexibility. The settings are transparently applied to both FastCGI and CGI mode. Previously made customizations (php.ini) remain intact. Learn more about custom PHP configuration in the section Customizing PHP Configuration.

  2. [+]  Quick preview of a website. Customers are able to preview their websites even if the associated domain names are not yet configured in DNS. The websites are available as subdomains under a hosting provider's domain name (say, <site-name>.hosting-provider-domain.com).

    Learn how to set up domain preview and use it.

  3. [+]  Customize the set of Apache modules. Administrators can decide which Apache modules they would like to switch off to achieve better performance and smaller RAM footprint (most relevant for VPS hosting providers). This tuning does not change any values in service plans, so be sure to align the module set changes with the hosting settings you offer to avoid offering features that are turned off.

    Learn more about the Apache modules customization.

  4. [+] (Only for Linux) Outgoing e-mails from a customer's exclusive IP. Outgoing e-mails are sent from a dedicated IP address owned by a customer, thus reducing the risk of blacklisting the whole server for spam. Subscriptions hosted on a single shared IP address will use this shared address for outgoing e-mail (instead of using the IP address occupied by Panel). The feature requires Postfix 2.7+ and is supported on the following operating systems:

    Learn more

  5. [+]  Quick search. Panel users can promptly find service plans, customer accounts, domain names, domain aliases, mailboxes, mailing lists, users, roles and also run operations from Tools & Settings, the left navigation menu of the Server Administration Panel, and the tabbed menu of Control Panel and by using tools on the Websites & Domains tab. The search feature is available in all views, including Power User View and Simple View, but is limited to tools available in a particular Panel. For more details about this feature and the Panel interface in general, see Becoming Familiar with Panel GUI.

  6. [+]  Optionally restrict users to access only one subscription. Customers can specify that a certain auxiliary user can log in only to a certain subscription if the customers have multiple subscriptions on the same hosting account. This feature also facilitates upgrade and migration from earlier Panel versions – former domain administrators are now restricted to only their subscription instead of being switched off (as before).

    Learn more in the (Advanced) Configuring Access to Hosting Account section.

  7. [+]  Hosting management from Server Administration Panel. A new interface option allows administrators to manage hosting services directly in the Server Administration Panel. Before that, administrators could manage hosting only from Control Panel that opened in a new window. The option is turned on automatically on upgrades from 9.5 and earlier versions.

    Read more about this option in Becoming Familiar with Panel GUI.

  8. [+]  Unified Tools & Settings page. It is easier for administrators to locate certain Panel tools or settings as all of them are now available from the single Tools & Settings page. In earlier versions, Panel settings and tools were located on separate pages (Settings and Tools & Utilities), which required more time to find what was needed.

  9. [+]  Simple view for customers. Shared hosting providers can offer customers a simpler interface by hiding unnecessary interface elements of Control Panel. Learn more

  10. [+]  Simple view for administrators. VPS and dedicated server providers can offer power users a simpler interface by hiding unnecessary elements in the user interface. Alternatively, Panel administrators themselves can voluntarily switch to Simple view and select the tools they would like to use. The view is activated in Settings > Interface Settings or in the initial configuration wizard. Learn more

  11. [+]  Usability improvements on the Domains page.

    Learn more about hosting services management in Managing Subscriptions.

  12. [+]  Mailbox size in the mailboxes list. Panel users can view the disk space occupied by each mailbox in the mailboxes list on the Mail tab in Control Panel.

  13. [+]  (Only for Linux) Native Postfix configuration. Panel configures Postfix in its native way instead of using the Qmail-compatible configuration.

  14. [+]  Download log files via FTP. Customers can download site logs through FTP in addition to downloading through Control Panel.

  15. [+]  IPv6 support for PTR. Panel users can create DNS zones for IPv6 as they did for IPv4.

  16. [+]  Administrators have no need to configure a domain name for SSO. Panel and Business Manager can work together, even if their IP addresses are not resolved to domain names (though this is a desired behavior).

  17. [+]  (Only for Linux) Availability of version-free EZ templates We offer one EZ template that can be upgraded to any other future version of Panel. This makes it easy to stay up-to-date.

    Learn more.

  18. [+]  (Only for Linux) Mailboxes do not accept new mail if the mailbox quota is exceeded. Both Qmail and Postfix will reject incoming mail when the target mailbox is over quota instead of bouncing it as before. The previous behavior was known as backscattering and might have caused the Plesk server to be included in anti-spam DNS blacklists.

  19. [+]  Improvements in working with subdomains. The concept of subdomains was revised to embody the following improvements:

  20. [+]  Update and upgrade availability control and indication. Panel introduces a number of features that make keeping Panel up-to-date even easier:

    Learn more about update and upgrade settings.

  21. [+]  Backup Manager improvements. We added a number of new features to the Backup Manager tool, which make it even handier:

    Additionally, Panel prevents backup failures caused by insufficient disk space in the following two ways:

    Learn more about configuring backup settings

  22. [+]  Migration tools refinement. Panel meets customer needs and introduces long-awaited features in migration tools:

    Learn more about Panel data migration in Migrating Data from Other Hosting Platforms.

  23. [+]  Reorganization of overuse options. In earlier versions, there were three overuse options:

    We rearranged the options to better indicate the actual outcome of each choice. For more information about resources overuse, see Resources.

  24. [+]  Adding files to archive in File Manager. Customers can add files and folders to an archive using the new Add to Archive button in the File Manager tool (in Control Panel, on the Websites & Domains tab).

    Learn more about working with File Manager.

  25. [+]  New supported operating systems. Panel can be installed on the following new operating systems:

  26. [+]  Improved themes structure. The structure of Panel themes is heavily refined from legacy code making it easier to customize the Panel look and feel.

  27. [+]  Support for new languages. The Brazilian Portuguese locale (pt-BR) is now supported.

  28. [+]  Two apps can share the same directory. Customers can install a website app to a directory occupied by another app. Practically this means that installing an app to docroot does not block further installations to docroot. Administrators can prohibit this feature in panel.ini. Learn more

  29. [+]  New site_* event handlers. The list of event handlers was expanded to support new operations of creating, updating, and deleting sites, domain aliases, and subdomains. Learn more about event handlers

  30. [+]  Parallels Plesk server monitoring and management from mobile devices. Administrators can view the information about Panel servers on their Android and BlackBerry devices using Parallels Plesk Server Monitor. Moreover, with Parallels Plesk Server Manager that will become available shortly, administrators can use their mobile devices to take control over various Panel functions. You can run the applications on the following devices:

  31. [*]  The user experience of working with phpMyAdmin is improved by removing a warning about the difference between the PHP MySQL library version and the MySQL server version.

  32. [*]  The list of a customer's subscriptions is now sorted by subscription's name.

  33. [*]  Administrators can refresh Parallels Health Monitor to let the tool detect hardware changes and update the statistics.

    Read more about Health Monitor.

  34. [*]  During Panel upgrade, Parallels Installer shows the notification that Panel 10 is not compatible with hMailServer and offers the ways to migrate to another mail server.

  35. [*]  Website apps that do not meet limitations of APS support are not shown to customers. More accurately, Panel does not show apps that use PVC, mail, and DNS aspects.

  36. [*]  A website administrator's e-mail was removed from default site pages to prevent e-mail stealing and spamming.

  37. [*]  Administrators can force Panel to restart the Apache web server gracefully. See http://kb.parallels.com/en/112020 for details.

  38. [*]  Customers can see a more informative error message when they encounter a problem with backing up additional domains.

  39. [*]  Panel now applies PHP settings to domains in the correct order: server-wide settings, then Panel-defined settings, then per-domain settings.

  6. [+]  New command-line utilities. A number of command-line utilities are now documented, namely:

  7. [*]  Administrators can set up the SSO service to identify servers by IP addresses (in addition to host names). The system of Business Manager and connected Panel servers will work even if the Business Manager's IP does not resolve to a domain name.

  8. [*]  Automatic orders processing provides the new option to accept all incoming orders automatically.

  1. [+]  Blog. The Blog module gives users the ability to add multiple blogs on their website. Users can post their thoughts, news and other interesting bits of information by creating blog posts in a blog module the same way they create a page.
