HHVM ending support for PHP

The HHVM project has announcedthat the Hack language and PHP will truly be going separate ways. The HHVMv3.30 release, due by the end of the year, will be the last to support codewritten in PHP. "Ultimately, we recommend that projects eithermigrate entirely to the Hack language, or entirely to PHP7 and the PHPruntime." HHVM was first announcedin 2011 as a compiler for the PHP language.
