Jupyter-console

- When using a kernel that the console did not start, exiting with Ctrl-D now leaves it running [127](https://github.com/jupyter/jupyter_console/pull/127)
- Added Ctrl-\\ shortcut to quit the console [130](https://github.com/jupyter/jupyter_console/pull/130)
- Input prompt numbers are now updated when another frontend has executed code in the same kernel [119](https://github.com/jupyter/jupyter_console/pull/119)
- Fix setting next input with newer versions of prompt_toolkit [123](https://github.com/jupyter/jupyter_console/pull/123)
- Ensure history entries are unicode, not bytes, on Python 2 [122](https://github.com/jupyter/jupyter_console/pull/122)

- New `ZMQTerminalInteractiveShell.true_color` config option to use 24-bit colour
- New `ZMQTerminalInteractiveShell.confirm_exit` config option to turn off asking 'are you sure' on exit
- New `--simple-prompt` flag to explicitly use the fallback mode without prompt_toolkit
- Fixed executing an empty input
- Fixed formatting for code and outputs from other frontends executing code
- Avoid using functions which will be removed in IPython 6

Interactive Shell architecture

- Disinherit shell class from IPython Interactive Shell. This separates jupyter_console's `ZMQTerminalInteractiveShell` from IPython's `TerminalInteractiveShell` and `InteractiveShell` classes [68](https://github.com/jupyter/jupyter_console/pull/68)
- Update SIGINT handler to not use the old interactive API shell [80](https://github.com/jupyter/jupyter_console/pull/80)

Image Handling improvement

- use PIL as default image handler [79](https://github.com/jupyter/jupyter_console/pull/79)
- better indication of whether image data was handled [77](https://github.com/jupyter/jupyter_console/pull/77)

Prompts improvement

- use prompt_toolkit 1.0 [74](https://github.com/jupyter/jupyter_console/pull/74)
- don't use prompt_manager [75](https://github.com/jupyter/jupyter_console/pull/75)
- remove `colors_force` flag that have no effects [88](https://github.com/jupyter/jupyter_console/pull/88)

- fix for readline history
- don't confuse sys.path with virtualenvs
