Joomla is now at version 3.7.3, which was released on July 4th. You can tell this is a truly international commuinty, as they didn't think twice about making all us US-based System Administrators work on the 4th to upgrade software.
The other software is the version of the PHP programming language in which Joomla is written. We were on the 5.6 version, we've now upgraded to version 7.0.12. (Don't ask "What happened to version 6?" It's a sad tale).
Hope you're all well.
