Magento 2.1.18 is the final 2.1.x release. After June 2019, Magento 2.1.x will no longer receive security patches, quality fixes, or documentation updates.
To maintain your site's performance, security, and PCI compliance, upgrade to the latest version of Magento.

Updater application

This topic is obsolete. Magento no longer has a separate updater application.

If you are a contributing developer who installed the Magento application by cloning the GitHub repository, see instead Update the Magento application.
