+  * Added support for bitbucket-oauth configuration
+  * Added warning when running composer as super user, set COMPOSER_ALLOW_SUPERUSER=1 to hide the warning if you really must
+  * Added PluginManager::getGlobalComposer getter to retrieve the global instance (which can be null!)
+  * Fixed dependency solver error reporting in many cases it now shows you proper errors instead of just saying a package does not exist
+  * Fixed output of failed downloads appearing as 100% done instead of Failed
+  * Fixed handling of empty directories when archiving, they are not skipped anymore
+  * Fixed installation of broken plugins corrupting the vendor state when combined with symlinked path repositories

 ### [1.0.0-beta2] - 2016-03-27
