The 'may be flaws' can just be a caution saying that since they are not coding anymore they won't find any if there are some. Hopefully the community will pick it back up and re-start or start a new project.

It just let me see that I have a single point of failure in my preps. If LibreOffice were to stop development today I can use Apache OpenOffice or KDEOffice. If Firefox or Thunderbird stops today I can use Chromium or Konqueror and Kmail. If Slackware stops today I can use Unbuntu or Deadrat or whatever. But if Truecrypt dies I realized I haven't installed or tested any other programs. I suppose I could still decrypt on my tablet and have them unencrypted but I could just do that today with TrueCrypt, it doesn't future proof me.
