PHP runtimes and extensions update

Change effective on 03 August 2017

The following new runtime versions are now available for PHP applications:

  • PHP 5.6.31
  • PHP 7.0.22
  • PHP 7.1.8

The following PHP extensions have been added or updated:

  • ext-amqp, version 1.9.1
  • ext-blackfire, version 1.17.3
  • ext-mongodb, version 1.2.9
  • ext-newrelic, version
  • ext-phalcon, version 3.2.1
  • ext-pq, version 2.1.2
  • ext-rdkafka, version 3.0.3
  • ext-redis, version 3.1.3

The version of Composer that is used during builds and available at runtime is now 1.4.2.

The newrelic and blackfire extensions will no longer be automatically enabled during Heroku CI builds.

An issue has been fixed that prevented applications which use the PHP buildpack as a require-dev Composer dependency to build on Heroku CI.
