Apache HTTP Server 2.4.6 was released, which is for reverting a broken fix for PR54948 that was applied to 2.4.5 (which was not released) and found post-2.4.5 tagging. I heard Apache HTTP Server 2.4.5 broke vhost mapping.
I downloaded httpd-2.4.6-win32-VC9.zip (16 Jul) from the ApacheLounge for My WindowsXP server. The new httpd.conf has the next four additional lines which are all commented.
