[arch-general] Update register/log

Is there a register or log that lists the history of package updates. I need to know what versions of encfs and openssl were updated and when. I am still unable to mount my 1.5 year old volume because of broken encfs and openssl update. (I did read all the bug reports associated with this, they recommend downgrading to openssl 0.9.8l, which I already tried) Manne
