Hi, I'd like to bump our libxml2 minimum version requirement from 2.6.11 (released July 2004) to 2.7.6 (released Oct 2009). I've picked this specific version because it is provided by RHEL 6, which means it's so prehistoric that any reasonable system should have it.
Increasing the minimum version requirement allows us to drop many version checks in the source code and most importantly avoids a number of conditionally available methods in DOM. It's a bad state of things if you can run a recent version of PHP, but some methods are not available because the libxml2 version is too old. PR at https://github.com/php/php-src/pull/3524. If there are no objections, I'll merge this next week. Regards, Nikita
