Software Versions and why they are important

PHP, Zen Cart and JavaScript library versions

Half the battle of security is simply ensuring your software is up to date. Software is versioned so that you can tell at a glance if you are running the current release.

Zen Cart version

The version information for Zen Cart, PHP and MySQL article explains how to determine your Zen Cart version.

If you are not running the current version, you should start planning your Zen Cart upgrade. An explanation of the importance of upgrading is provided in the article why should I upgrade?

PHP version

The version information for Zen Cart, PHP and MySQL article explains how to determine your PHP version.

PHP’s Version Support Policy will tell you if your PHP version is still supported. Remember: old versions are not PCI compliant, and are not deemed “secure” if they are out of the maintenance period.

JavaScript library versions

JavaScript libraries such as jQuery are updated as issues are found. It’s best to use the most current version of each library you use.

The easiest way to check if your JavaScript libraries are up to date is to use the Google Lighthouse tool.
