no clear communication on exactly what the POS weakness is.
No one ever said there would be. They said this was going to be kept from the public out of respect for other coins. If you read this:
https://bt.irlbtc.com/view/637704.msg7723627#msg7723627you see:
"After extensive testing we believe we may have uncovered an underlying flaw that can affect the vast majority of PoS coins and for that reason and until we issue a patch in the next update, for the security of this coin and respect for other coins, we will refrain from making "the vulnerability" public knowledge."
It might be inferred now that the patch has released they may divulge information about it, but that was never explicitly stated.
