ipythonapi的稳定性

在ipython4中使用pymc3时，我发现一些与ipython的api有关的错误：

ShimWarning: The `IPython.html` package has been deprecated. You should 
import from `notebook` instead. `IPython.html.widgets` has moved to
`ipywidgets`. "`IPython.html.widgets` has moved to `ipywidgets`.", ShimWarning)
./lib/python3.4/site-packages/IPython/utils/traitlets.py:5: UserWarning: IPython.utils.traitlets 
has moved to a top-level traitlets package.
warn("IPython.utils.traitlets has moved to a top-level traitlets package."

api的这一部分是否足够稳定，值得我尝试稳定其上的代码，还是仍在进行大量开发？

这是IPython api的一个问题。有一个正在等待合并的拉取请求消除了此警告
