After not having updated Jenkins for quite a while I thought I might as well go directly to version 2 for the supported platforms. So here it is: Jenkins 2.38 for ReadyNAS OS 6 (x86 and ARM platforms) and RAIDiator 4 (x86 only).
When upgrading from previous versions please be advised that Jenkins will now automatically secure the web interface if you haven’t already done so. This is done using basic authentication so you might be asked for a username and password on first login. The username to use is “admin”, the password can be found on the “Installed Add-ons” page on RAIDiator 4 or by entering the URL http://ip.of.your.nas/apps/jenkins/InitialPassword in your browser (ReadyNAS OS 6). Please allow some minutes of update work before trying.
