Development version

This document describes in-flight development work.

The CodeMirror js library has been updated fron 2.23 to 2.32 this might induce a few changes in behavior of keymaps in the notebook, especially intenting/deindenting blocks that is now bound to Ctrl+] and ctr+[

• Exception types can now be displayed with a custom traceback, by defining a _render_traceback_() method which returns a list of strings, each containing one line of the traceback.

Backwards incompatible changes

• Calling InteractiveShell.prefilter() will no longer perform static transformations - the processing of escaped commands such as %magic and !system, and stripping input prompts from code blocks. This functionality was duplicated in IPython.core.inputsplitter, and the latter version was already what IPython relied on. A new API to transform input will be ready before release.
