loadJSON does not support parsing HTML.
Nor should it need to, since UC URLs are supposed to be to the JSONP file.
The .html extension is added automatically by downloadService when postBack is supported.

@kohsuke prefers that the option to disable signature checks not even be presented unless -Dhudson.model.DownloadService.noSignatureCheck is used.
(cherry picked from commit 54c85007)

Be a bit paranoid and ensure the admin has CONFIGURE_UPDATECENTER before turning off signature checks.

This is already handled by ListView.Listener (other kinds of views are now responsible for their own listeners).
And handled better—if there are no actual changes
(because you have no such views, or they do not mention this job), there is no need to save.
Also moving the actual saving in those remaining cases out of the lock on the ListView itself, just in case.

[JENKINS-21984] Disabling cert check on updateDirectlyWithJson since the certificate is now expired, and it is no good to have a test which is known to start failing at a particular time in the future!

Introduce VirtualFile.run method to batch together commands.
This should restore pre-ArtifactManager performance for workspace browsing.

[FIXED JENKINS-21780] Revised fix to make cache work properly without introducing a new remote call to find hash codes.

[FIXED JENKINS-21855] Add preview for parameter descriptions

[FIXED JENKINS-21958] FilePath.copyRecursiveTo given a scanner including a symlink but not any regular file in the same directory would neglect to create the parent directory on the destination and thus not copy the link.
(Util.createSymlink is partly to blame for not throwing a descriptive IOException when it fails to create a link,
but this is its historical behavior needed for compatibility.
copyRecursiveTo also continues to suppress error text from this method because there is nowhere for it to go.
Perhaps need a new variant of createSymlink that is guaranteed to either have created the link or throw an exception.)

Seems to work in 8.0 at least for some functional tests.
Developers can always disable it privately if they run into issues.
