Focus of Development
IPython is now developed on GitHub, please go to:
The main branch of development for IPython. Stable releases are made from this branch, it is the equivalent of a trunk in a traditional SVN-style setting.
As of August 4 2009 (when version 0.10 was released), the trunk is undergoing significant changes and API stability is NOT guaranteed. This will result in a significantly refactored IPython, and will be released as 0.11 (and later) once ready.
So unless you are actively following our development and are aware of the potential compatibility issues, do not update regularly from trunk in your production environment. We will update this notice when the API stabilizes again.
