* Break: For forward compatibility, you should change your deployment scripts to run `composer install --no-dev`. The install command will install dev dependencies by default starting in the next release
* Break: The `update` command now has --dev enabled by default. --no-dev can be used to update without dev requirements, but it will create an incomplete lock file and is discouraged
* Break: Removed support for lock files created before 2012-09-15 due to their outdated unusable format
* Added `prefer-stable` flag to pick stable packages over unstable ones when possible
* Added `preferred-install` config option to always enable --prefer-source or --prefer-dist
* Added `diagnose` command to to system/network checks and find common problems
* Added wildcard support in the update whitelist, e.g. to update all packages of a vendor do `composer update vendor/*`
* Added `archive` command to archive the current directory or a given package
* Added `run-script` command to manually trigger scripts
* Added `proprietary` as valid license identifier for non-free code
* Added a `php-64bit` platform package that you can require to force a 64bit php
* Added a `lib-ICU` platform package
* Added a new official package type `project` for project-bootstrapping packages
* Added zip/dist local cache to speed up repetitive installations
* Added `post-autoload-dump` script event
* Added `Event::getDevMode` to let script handlers know if dev requirements are being installed

* Added -vv and -vvv flags to get more verbose output, can be useful to debug some issues
* Added COMPOSER_NO_INTERACTION env var to do the equivalent of --no-interaction (should be set on build boxes, CI, PaaS)
* Added PHP 5.2 compatibility to the autoloader configuration files so they can be used to configure another autoloader
