They have deprecated php 5.6 and 7.0
"Deprecated and removed itemsDeprecation of PHP versions 5.6 and 7.0
We have deprecated PHP 5.6 and PHP 7.0 and will remove support for them in a future version."
This means just as it says that starting on their next version (most likely) you wont even have the option for php 5.6 or 7.0 on your cPanel account.
So be sure "if" you install Oxwall 1.8.4 on a server that has cPanel 84, that before their next version release, that you do one of the following:
1. Make arrangments to skip further updates of cPanel either with your host or on your dedi/vps machine(not recommended).
2. Update your version of Oxwall to run on php versions "greater than 7.0" because you wont even have those options anymore going forward.
3. Move to a new shared host that runs "cPanel 84 or below" and does not plan to upgrade.
Im sure there will be alot of people throwing a fit when this happens so be ahead of the game and make plans now folks so that you dont get caught in putting out fires at the last moment.
