• Break: The install command now turns into an update command automatically if you have no composer.lock. This was done only half-way before which caused inconsistencies
• Break: By default the remove command now removes dependencies as well, and --update-with-dependencies is deprecated. Use --no-update-with-dependencies to get old behavior
• Added support for update channels in self-update. All users will now update to stable builds by default. Run self-update with --snapshot, --preview or --stable to switch between update channels.
• Added support for SSL_CERT_DIR env var and openssl.capath ini value
• Added some conflict detection in why-not command
• Added suggestion of root package's suggests in create-project command
• Fixed create-project ignoring --ignore-platform-reqs when choosing a version of the package
• Fixed search command in a directory without composer.json
• Fixed path repository handling of symlinks on windows
• Fixed PEAR repo handling to prefer HTTPS mirrors over HTTP ones
• Fixed handling of Path env var on Windows, only PATH was accepted before
