I noticed that a Plugin update (Friends Plugin) had a problem (missing constant) and it looks like the Problem is that I have updated the Plugin but not the Core.
I was under the impression that Plugins can state minimum versions (at least in the store it is listed as 1.7.5 and I had 1.7.4), but it was still offered as an update. Is this expected and can it be improved? (plugin.xml seems to have no such entry for the friends plugin).
I think it is quite common that people update plugins more often than the core (given it needs more testing and merging custom code changes).
