dira | A question to which I assume the answer is "Yes, in [an obvious location]."

Is there a reasonably concise summary anywhere of all the changes-of-membership TAI went through? Preferably with dates and estimated levels of acrimony? I, er, never cared quite enough to remember how the earlier one(s) went. And still do not actually care all THAT much, I just want to be sure I have the right general idea about it. For, you know. A thing. Which I am not at all writing.

[To be clear: An ENTIRELY DIFFERENT thing I am not writing than (or, if you prefer, to) last week's apocalypse-geography question. As of now I am pretty definitely genuinely not writing the apocalypse one.]
