Yesterday, without warning, the SourceForge page for file and disk encryption package TrueCrypt popped up this message: “WARNING: Using TrueCrypt is not secure as it may contain unfixed security issues”. Discussions on reddit, Metafilter and other sites are full of speculation but nothing definitive. The only version available for download, v7.2, only allows for decrypting of existing archives.
TrueCrypt did a fund raiser for a security audit and the initial review found no backdoors (additional review was in progress).
I will update if I hear anything. I am a TrueCrypt user so this directly affects me.
