Release dates of Testcomplete patches are not available

Its a requirment when it comes to postmortem bugs.

Let me give you a simple example.

From last few month there were testcases that were failing but there were other that have priority and we were busy fixing them.Now when we have started investigation and looking at automation code and app code there isn't any change that lead to testcase failure .

Now we are trying to figure out what could be the possible reason.Oe of the possible cnadiadte is may be Testcomplete upgrade.

I know dates are available  but it would be more helpful ,if they are also listed on version history page.
