We first launched our WordPress AutoUpdater in 2012. Some tweaks were made to the system a year later, when the original AutoUpdate feature was included in the WordPress core, but we continued to rely primarily on our own system for our customers. The SiteGround AutoUpdater has been used successfully for the last 5 years and has kept a lot of our customers up-to-date and safe from hacks. Thanks to it, more than 70% of the WordPress installations on our servers have been constantly using the latest software version. However, we have been thinking for a while how to get this percentage even closer to 100. The recent security issues with WordPress REST API motivated us to introduce a change into the system that increased the upgrade rate to more than 90%.
