Hi,
we have noticed that the "all updates" list displayed right after login differs from one user to another, although they are members of the same groups and have the same rights. To me, the most recent updates are from Aug 29th, whereas my colleague sees updates from today and yesterday (not only own updates, in both cases).
Confluence V6.7.1 on Linux server - in V6.2.1 on another server we get both the same list.
