Panel Updates

Updates are fixes that enhance Panel security and stability. There are four types of updates:

• Security updates.
  These updates address security vulnerabilities. Such vulnerabilities may be exploited by hackers attempting to get access to your server. We strongly recommend that you apply security updates as soon as possible. Panel always warns you about missed security updates on the Home page.

  Note: Some security updates that Parallels considers to be mandatory are applied automatically regardless of your update policy.

• Important updates.
  These are updates that significantly improve Panel reliability. We strongly recommend that you apply such updates once they become available.
• Recommended updates.
  Recommended updates improve the overall stability or introduce enhancements developed after the Panel release.
• Optional updates.
  These are minor fixes and enhancements, which do not have any serious impact on your work in Panel and do not require immediate installation.

Updates are distinguished by types only for your convenience: Update type just indicates the urgency of applying an update. For example, a security update should be applied as soon as possible, while an optional update can be installed at any convenient time.

Applying Panel Updates

Updates can be applied only to a current Panel version. Thus, Panel does not change its version after an update: Information about the applied update is just added to the product version name, e.g. Panel 10.3.0 Update #12. Updates are free of charge and available to all Panel installations regardless of their license key.

You can update Panel in two ways:

• Manually from the System Overview group of the Home page. This page contains the information about the latest available update including its type and a link for applying the update.
• Automatically (recommended). If you activate automatic updates at Tools & Settings > Update and Upgrade Settings, Panel will check for updates once a week. If updates are available, Panel automatically downloads and installs them.

Note: Panel updates are applied sequentially. Therefore, you cannot install only a specific update or skip one of the updates.
