===== About upgrading =====
Whenever upgrading from a previous version of OAR, please mind having a look at the configuration file, especially with regard to the need to [[harden oarsub oarsh vs openssh options]]. Fresh installs or OAR 2.5.9 will come with a default configuration file that integrates the hardening.
