LIVE UPDATING OF A SHARED PLUGIN REGISTRY WITH NO SERVICE LOSS FOR ACTIVE USERS

Embodiments can enable the uploading of a newer version of a plugin package to a plugin service without affecting an existing user session that is using an older version of the plugin package. When a new user session begins, the plugin service can monitor one or more plugin packages and the versions used during the new user session. Throughout the user session, the plugin service continues to make the plugin packages available to the user regardless of newer versions being uploaded to the plugin service. In the meantime, multiple clients with different user sessions may be using different and possibly newer versions of the plugin packages at the same time. The plugin service can remove an older version of a plugin package when it determines that there are no longer any active user sessions utilizing the older version of the plugin package.
