I've just installed the latest LTS into a dev environment I am using to verify our upgrade to OpenJDK 11 from OpenJDK 8.

I installed our plugins, one of which is SAML. The 2.333.vc81e525974a_c version installed happily enough, but the latest seems to be unavailable for the LTS:

``` 
SAMLVersion4.372.v89f13e4c9e97]
 The new version of this plugin is marked as incompatible with the installed version. This is usually the case because its behavior changed, or because it uses a different settings format than the installed version. Jobs using this plugin may need to be reconfigured, and/or you may not be able to cleanly revert to the prior version without manually restoring old settings. Consult the plugin release notes for details.
```

Is this intended? Is there any documentation anywhere as to why the latest SAML doesn't work in the latest LTS?
