• Added workaround for xdebug performance impact by restarting PHP without xdebug automatically in case it is enabled
• Added --minor-only to the outdated command to only show updates to minor versions and ignore new major versions
• Added --apcu-autoloader to the update/install commands and --apcu to dump-autoload to enable an APCu-caching autoloader, which can be more efficient than --classmap-authoritative if you attempt to autoload many classes that do not exist, or if you can not use authoritative classmaps for some reason
• Added summary of operations to be executed before they run, and made execution output more compact
• Added php-debug and php-zts virtual platform packages
• Added gitlab-token auth config for GitLab private tokens
• Added --strict to the outdated command to return a non-zero exit code when there are outdated packages
• Added ability to call php scripts using the current php interpreter (instead of finding php in PATH by default) in script handlers via @php ...
• Added COMPOSER_ALLOW_XDEBUG env var to circumvent the xdebug-disabling behavior
• Added COMPOSER_MIRROR_PATH_REPOS env var to force mirroring of path repositories vs symlinking
• Added COMPOSER_DEV_MODE env var that is set by Composer to forward the dev mode to script handlers
• Fixed handling of annotated git tags vs lightweight tags leading to useless updates sometimes
• Fixed case insensitivity of remove command
• Fixed support for git 2.11
• Fixed output from zip and rar leaking out when an error occured
• Removed hash from composer.lock, only content-hash is now used which should reduce conflicts
• Minor fixes and performance improvements
