Thanks, it looks like the documentation has been updated after the 
attempt to work out the new way of customzing prompts:
<http://ipython.readthedocs.io/en/latest/config/details.html#MyPrompt
s>

So this is what I came up with:
"""
config = get_config()
TIS = config.TerminalInteractiveShell

from IPython.terminal.prompts import Prompts, Token

class CustomPrompts(Prompts):

    def in_prompt_tokens(self, cli = None):
        return [(Token.Prompt, '>>> ')]

    def out_prompt_tokens(self):
        return [(Token.OutPrompt, '')]

    def continuation_prompt_tokens(self, cli = None, width = None):
        return [(Token.Prompt, '...')]

TIS.prompts_class = CustomPrompts
"""

Unfortunately setting color (like `'{color.LightCyan}>>> '` seems not 
to be supported anymore.

In all, a substantial loss of ease of configuration for IPython 
users. "pretty low lever" as the developer said.
