Hi,
New user with a quick note, it may be worth noting in your release notes that for *EL users upgrading from Frustrick to Grebo need an additional rpm, php-json otherwise you're presented with a blank screen. The tip for me was the following error on a clean grebo install:
[Wed Nov 28 15:07:18.942998 2018] [php7:error] [pid 15549] [client 161.50.17.173:54304] PHP Fatal error: Uncaught Error: Call to undefined
