PC/OS OpenServer 8.4L will have many improvements involved as well. It will be more geared towards more applications and deployment roles. OpenServer 8.4 will also contain the new Remastersys and all of its improvements. This will be the last incremental release after this release maintenance packs will be issued for PC/OS OpenServer 8.4 until the next LTS.
Feedback was taken from OpenServer customers and the new roles are based on that feedback. Open64 will be based on Ubuntu 8.04 LTS until such time that Open64 Workstation 10.1 wich will be based on possibly Jaunty, once again feedback will be taken and the release will be well tested as always.
