Unmanaged development management
OK, this is pretty amazing. I'm going to give you the following quote, edited out only so that the product in question is not obvious:
The full ChangeLog ended up missing, because I only have the history from TESTVERSION-X in my SOURCECONTROLSYSTEM archives, but if you want to, you can puzzle it together by taking the RELEASEVERSION changelog and merging it with the TESTVERSION-A and TESTVERSION-B logs in the testing directory. The file that says "ChangeLog-RELEASEVERSION" only contains the stuff from -B onward.
You may already know what this is referring to. If you don't, let's just leave it at "major Open Source product." Ask yourself - is this quality development? "I can't tell you what's changed, but you can probably work it out by piecing together these three files... I won't bother doing that, though." I don't think so.
P. S. If I wanted this to be a slam, I'd outright tell you the product. It's more just an FYI.
