[Observium] RELEASE: Observium Community Edition 20.9

Hi Guys,

We've just released a new CE, version 20.9. The release covers 790 commits since the last release, and a very large number of changes!

The new release can be installed using the upgrade instructions in our documentation: https://docs.observium.org/updating/#upgrade-to-latest-major-release

Please make sure you meet these absolute minimum requirements beforehand:

MySQL 5.6.5 / MariaDB 10.0

PHP 5.6.26

Though we would recommend a PHP version above 7.1 and rrdtool versions above 1.7.

Thanks,

Adam.
