Any core Joomla upgrade will be run within 72 hours of release. We do testing of new releases on a test site first to ensure there are no bugs in them.
We also upgrade all 3rd party extensions on your site. As part of maintenance, we install several additional tools on your site like JCE Editor, Akeeba Backup, AdminTools, JW All Videos, and the many of the NoNumbers extensions.
Every month you will receive an emailed rollup of all software on your site that has been upgraded during that month.
