Cluster Policy Improvement

In the past PowerFolder Server used a cluster policy that is defined in the external load balancer e.g. Nginx or Apache. PFS v15.0.100 contains a default cluster policy in that it is defined that the new users / folders are automatically registered to the server that contains the minimum number of folders so that the storage and the server capacity can be used and managed in smart way and the resources remained balanced. For more infos please visit: Clustering Information

PowerFolder Server v15.1 the MSI-Client x64 can be directly downloaded from the homepage under clients-tab. Server admin can set the link for that in the admin dashboard< preferences < customizations < download URLs < Windows MSI client URL < path.

Please read this complete Release Notes and instructions before upgrading.
Please follow the regular upgrade documentation for Windows or Linux
