Hi all.

I have recently upgraded my doxygen version and recognized, that collaboration diagrams are not calculated correctly anymore since the update. I have tracked this issue down to come from a change between doxygen 1.7.4 and 1.7.5. Since then collaboration graphs often look just identical to inheritance graphs, although they have not done so before.

Of course I have made sure to test with different doxygen versions on an identical project setup with identical source code, to be absolutely sure, that this really solely caused by difference between 1.7.4 and older on the one and 1.7.5 and newer on the other side.

I think, example collaboration diagrams are giving the best explanation of what I am talking about:

1.7.4 output:

1.7.5 output for the same class in the same codebase with same settings:

Is this a known issue?

Is it intended?

If not, then is there a way to get the old behavior with current doxygen versions?

Thanks,

Stefan.
