Change effective on 16 December 2014
Instead of performing a
composer self-update on each deploy (a measure taken to ensure recently introduced features are available), PHP applications will now always use Composer version 1.0.0-alpha9 (the first new release in almost a year).
To prevent wrapping of message lines on standard 80-character wide terminals, all messages during build have been adjusted to cater for the decreased horizontal space available during HTTPS Git pushes due to the
remote: prefix for each message line that’s present on that Git transport.
PHP extensions required in
composer.lock that are already enabled by default are now no longer explicitly listed during the extension installation step on deploy.
