PHP versions 5.5.28, 5.6.12, 7.0.0RC1 available; new composer.lock requirements
Change effective on 21 August 2015
The following new PHP runtime versions are now available on Heroku:
- PHP 5.5.28
- PHP 5.6.12
- PHP 7.0.0RC1 (on cedar-14 only)
newrelic PHP extension has been updated to version 188.8.131.52.
composer.lock is now required if a
composer.json lists any dependencies in
require, even if none of these dependencies are user-land packages. It was previously possible to use a
composer.json only if the requirements consisted only of PHP versions and/or extensions, but more recent versions of Composer now generate a
composer.lock in that situation, too. As documented, the command
composer update --ignore-platform-reqs can be used to work around problems with missing local platform packages.
A warning will now be displayed if a
composer.json contains a
minimum-stability setting, advising developers to use stability flags instead.
