The warning is actually that if you upgrade to 1.4 you *may* have data loss if you try to downgrade again.
There are two kinds of warning on the screen: the first and most common is that it needs a newer version of Jenkins. The second is that it is not backwards compatible. The latest versions of Credentials, ssh credentials and ssh-slaves will all work on Jenkins 1.466+ without issue... Just there is a data format change in credentials and ssh-slaves so once you upgrade the data is migrated to the new format, so you will loose data if you subsequently downgrade the plugins (hence the warning) On Wednesday, 9 October 2013, Jon Schewe wrote: > Thanks, that got me going again. > > > On Wed, Oct 9, 2013 at 1:55 PM, William Soula < > william.so...@drillinginfo.com <javascript:_e({}, 'cvml', > 'william.so...@drillinginfo.com');>> wrote: > >> https://updates.jenkins-ci.org/download/plugins/ >> >> Will >> >> ------------------------------ >> *From:* jenkinsci-users@googlegroups.com <javascript:_e({}, 'cvml', >> 'jenkinsci-users@googlegroups.com');> >> [jenkinsci-users@googlegroups.com<javascript:_e({}, 'cvml', >> 'jenkinsci-users@googlegroups.com');>] >> on behalf of Jon Schewe [jpsch...@mtu.net <javascript:_e({}, 'cvml', >> 'jpsch...@mtu.net');>] >> *Sent:* Wednesday, October 09, 2013 1:44 PM >> *To:* jenkinsci-users >> *Subject:* How to get particular version of a plugin >> >> I just upgraded to LTS version 1.509.2 and found that I'm sing the SSH >> Credentials Plugin version 0.2 that has this bug[1].
