We are using the JobConfigHistory plugin (2.6) and have recently realized that no config changes have been saved to disk for many weeks. When clicking on the "Job Config History" link of a job, a list of changes appears, but the newest one is very old.

We therefore upgraded to version 2.10, but that did not really help:

• now the history seems to be working but is only available on the main page (global history of all changes)
• the new problem is that there are no more "Job Config History" links in the jobs, so it's hard to navigate to the interesting changes.

When moving back to 2.6:

• the links appear again in the jobs
• some recent changes (done while 2.10 was installed) appear!
• but the problem is again that new configuration changes are not stored (only old content and changes performed while 2.10 was installed)

Are these known issues?
We still use Jenkins 1.532.3, could that be the problem?
