I do not anymore, but did it decreased?
VeraCrypt is one of the main forks that has picked up popularity, and has addressed some of the minor concerns of the audit.
The hidden volume hasn't had a high degree of success when it comes to deniability [1]. Some leaks closed, probably not all. With the design, it may not actually be possible to close all the leaks. (Especially as "Stoned" can break the full-disk encryption).
TrueCrypt doesn't use the TPM (and nor does VeraCrypt), because the authors didn't believe it added any security whatsoever (as it can't defend against a hardware keylogger, despite making coldboot attacks harder).
TrueCrypt is vulnerable to coldboot, evil maid and the "Stoned" bootkit. Depending on your security concerns, that might be fine, it might not. Other solutions may be better when dealing with those attacks.

Edit: Ahh, read up a but. I wasn't aware "veracrypt hidden volumes" are already pretty stealthy. Would probably require some work to make it plausible though...like recent faked web browsing history.
Exactly. One of my favourite vids is Don't Talk To The Police, it's the right thing to (not) do.
