Old website update 22.214.171.124 -> 5.6.4
Option to update not available in the system settings and legacy docs athttps://legacy-documentation.concrete5.org/developers/installation/u... don't reveal much.
Extract the archive into your 'root/updates' folder and visit your System & Settings > Update concrete5 page.
Only PHP 7.2 available here but seems snappier ;-)
I need to put all the files from that download ? Or only a part of them ?
