I was installing a Koha site from source and got a syntax error from the "Order" directive since I am using Apache 2.4 and koha-http.conf is designed for Apache 2.2. It's an easy enough change to use "Require all denied" instead of "Order deny,allow\n Deny from all", but I wonder if we should update the file to use Apache 2.4 just to keep non-package installs more in-line with package installs (although I suppose there are quite a few differences between the Apache configuration files anyway). I was planning to submit a patch using mod_version, but that's an extension module, so I think it might be a bit much to expect people to install that just to run Koha out of the box. I notice openSUSE doesn't even have mod_version in the 42.2 repositories, so I'm just going to update my file to 2.4 sytnax, but thought I'd raise it here in any case.
