Upped Versions
I’m an Emacs girl myself, but many mac users prefer BBEdit, now up to BBEdit 8.0. Daring Fireball explains the appeal of BBEdit.
Quicksilver is up to β29.
DivX is up to 5.2.
Bookpedia is up to version 1.1.3. If you’d rather not pay for software, there’s a free program that does the same thing (cataloging books), more or less: Books for MacOS X.
