Changelog

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Break: Removed support for lock files created before 2012-09-15 due to their outdated unusable format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 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 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 discard-changes config option to control the default behavior when updating "dirty" dependencies
Added use-include-path config option to make the autoloader look for files in the include path too
Added cache-ttl, cache-files-ttl and cache-files-maxsize config option
Added cache-dir, cache-files-dir, cache-repo-dir and cache-vcs-dir config option
Added support for using http(s) authentication to non-github repos
Added support for using multiple autoloaders at once (e.g. PHPUnit + application both using Composer autoloader)
Added support for .inc files for classmap autoloading (legacy support, do not do this on new projects!)

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
