PHP and HHVM runtime, extension and web server updates

Change effective on 06 June 2014

Heroku’s PHP support received several updates:

  1. PHP 5.5.13 is now available. For the time being, due to reported backwards compatibility breaks in libraries such as Doctrine, 5.5.12 will remain the default version.
  2. HHVM 3.1.0 is now available.
  3. PHP extension gettext is now available, and the mongo and newrelic extensions have been updated to their respective latest versions.
  4. The default rewrites that proxy requests for .php files to PHP-FPM in Apache have been optimized for better compatibility with various rewrite and .htaccess scenarios.
