This morning I checked for plugin updates and was surprised to see the 2.12.1 release of the Pipeline Job and 2.6 release of Pipeline SCM Step plugins show up, given that I'm not running Jenkins 2.60, as they require. The warning it showed ("Warning: This plugin is built for Jenkins 2.60 or newer. Jenkins will refuse to load this plugin if installed.") was definitely helpful, as I now know not to upgrade these until I'm running 2.60+, but I was surprised to see them show up in the LTS feed at all.
Shouldn't the plugin page only show updates that are applicable to the LTS version currently being run?
EDIT: When I originally logged this, I was midway through an upgrade from 2.11 to 2.11.1 – I'd installed it, but hadn't bounced the service yet – so was seeing the 2.12.1 upgrade as being an option for the 2.11 version I was running at the time. Post-bounce, I now see the 2.12.1 upgrade as an option against the 2.11.1 version I'm running. Same result, just without the gray background from earlier.
