Joomla 3.8.6 Security & Bug Fixes release!
The Joomla project team has released version 3.8.6, a security and bug fixes release.
This is an important maintenance release for Joomla 3.8.5 regression bugs and a recommended upgrade for all Joomla 3.x series sites. As always, before any Joomla upgrade on your live website, take a backup just in case anything goes wrong.
The security fix addresses a low level SQLi vulnerability in User Notes and the bug fixes address various Joomla 3.8.5 regressions (session management and cookies improvements), PHP 7.2 compatibility issues and other bugs.
