The default tracebackmode will now skip frames that are marked with __tracebackhide__ = True and show how many traceback frames have been skipped. This can be toggled by using :magic:`xmode` with the --show or --hide attribute. It will have no effect on non verbose traceback modes.

The ipython debugger also now understand __tracebackhide__ as well and will skip hidden frames when displaying. Movement up and down the stack will skip the hidden frames and will show how many frames were hidden. Internal IPython frames are also now hidden by default. The behavior can be changed with the skip_hidden command and accepts "yes", "no", "true" and "false" case insensitive parameters.
