Atlassian Release Plugin for Managing Plugins
The Universal Plugin Manager (UPM) version 1.0 is out now.
UPM contains several modules that are implementations of the Atlassian REST plugin module type, and provides an interface for managing plugins. It allows users to perform tasks such as enabling and disabling plugins and plugin modules, installing new plugins and configuring plugin options. UPM also interfaces with the Atlassian Plugin Exchange, allowing the user to browse available plugins for a particular application, from inside that application.
