Updating Josetta to a new version
Josetta has been discontinued as of January 20, 2017. It is not developed any longer, and unsupported. This documentation is left available as a reference for past users.
When a new version is available, you should update as quickly as possible, to fix existing issues, including possibly security ones.
Download the new version from our site
The download area is on this page. You can then install it through Joomla! installer, just like you installed the first time.
You don't need to, and should not, remove a previous version before installing a new one.
