[note to me] I should submit news more frequently [/note to me]
I believe 0.2 was a small step for men, but a giant leap for mankind! This release uses classes which is more efficient and safer. This release no longer uses the $GLOBALS variable, so they're all back to the developer. Besides, by using classes you can work on several Zipfiles at the same time, just define a new class.
Coming for the next version (which I don't have much time for, just be patient please): memory saving by using the filesystem as swap space when nessecary (I believe archives can't get any larger then the maximum memory reserved for PHP, which is usually set to no more then 8MB, which is way too small), and in the far future, reading zipfiles.
