Don't remove old versions of pytx from pypi about threatexchange

Hmm. Not sure how that works but we never released pytx on PyPi before 0.1.2 was accepted.

I agree though that it should keep all of the versions as they go forward! Thanks for pointing this out I might not have noticed :)

That's odd - there was a 0.1.0 release on pypi at some point. Oh well.

I consider this sufficiently addressed :).

there's an odd issue in PyPi that doesn't let you replace versions, I had accidentally uploaded a broken version and couldn't replace it, so now it's gone.

I'm trying to plug pypi with travis to make sure only valid commits gets uploaded to pip, stay tuned :)
