With this sync we've upgraded to the latest stable version of PHP, 5.6, for the first time likely since the release of PHP 5. There might be outstanding issues due to language differences between 5.6 and 5.4, so please open bug reports with details. In general, this version of PHP should offer significant performance improvements through the integration of an opcode cache, in addition to making it easier for us to keep software updated.
