Today Joomla is 18 years old. It is also 2 years since the release of Joomla! 4, and the end of official support from the Joomla Volunteer Community for Joomla! 3
A huge debate of gratitude is owed to everyone who worked on the Joomla 3 series. Many businesses owe their success to Joomla 3, and it has been a long and productive journey.
If you still have a joomla 3 site, you will have a notice in the administrator section, which reads.
"Support has ended for your version of Joomla 3.10. Migrate to Joomla 4 as soon as possible."
We encourage everyone with a Joomla 3 site to migrate to Joomla 4, as this is where the communities focus lies. In a few months, Joomla 5 will bring even more stability, speed, security and functionality to your sites.
