Less than a week after 8.0, we have our first point release for concrete5 version 8. 8.0.1 fixes a number of bugs, a couple security issues and incorrect settings. 18.104.22.168 fixes some PHP version incompatibilities, security issues. Both are highly recommended; if you're running 5.7, grab 22.214.171.124 straight away. If you're on version 8, 8.0.1 is what you want.
