[Changelog] python-steem 0.3.0

python-steem 0.3.0

This release constitutes a major update with refactored code from
piston.

Refactoring

A major changes had been happened under the hood, namely, most libraries have been moved from piston into python-steem. This allows to use Steem() with as little code as this:

from steem import Steem()

In order to not break compatibility with your existing code, you can still load Steem() and all the other classes from piston.steem, however, you will see a depracation error.

In general, developers can replace all appearances of:

from piston.XXXXXXX import YYYYYYY

from steem.XXXXXXX import YYYYYYY

Furthermore, the steemexchange is now more closesly integrated into Steem and can be used like this:

from steem.steem import Steem
from steem.dex import Dex

dex = Dex(Steem())

This will also load your local wallet that you can manage through python, or piston. Note that the format of some calls are now different by unified.
