Hi,
I have just downloaded and installed a latest version of QT Wallet from bitcoin.org
The date of EXE is June 1, 2013.
I was under impression that there were some latest updates ti fix a security issue.
What is going on here?
The date is irrelevant. Look at the version number, if it's 0.9.1 then you are fine.
The devs probably didn't bother updating the date.
