If the developers left this "message" that 7.2 might be compromised, what kind of guarantee is there that 7.1 isn't also compromised
The only kind of guarantee there is: an open, publically funded audit of the code. That's the point of this exercise, even before people realized that blindly trusting the TrueCrypt code was a mistake, and that an audit by non-government researchers was needed.
You're assuming the binary is actually compiled from the source being audited. Once the source audit is complete, AND a recompiled version FROM THAT SOURCE is available, then I might consider using TC again...
