Simultaneous Issue Editing

When editing a ticket, Redmine used to give an error if another user has edited the same ticket since you opened it.

Redmine doesn't seem to do this any more, resulting in the first edit being overwritten without warning.

I can't seem to find the change log entry for this change, anyone know if it was intentional?

Mentioning the word Concurrent in case that draws more attention :)

I've investigated this a little more and filed a bug: #5280
