• Updated the base images used in all Dockerfile from bionic to focal.
• Added Mosquitto (MQTT client) Ubuntu ppa repository to install the latest version and fixed ownership issue when accessing Let's Encrypt certs.

Release of MCCI Production Code

This is a full release with many changes and improvements.

• improved documentation
• support for MQTTS
• use of NGINX rather than Apache
• Improved in-built email support

We have found that updating an existing (pre v1.0.0) install to v1.0.0 is straightfoward, having updated multiple systems. Still, we always suggest people be sure that they have adequate backups, as upgrades are notoriously hard to test.

Initial release

As used in production by MCCI for over a year.
