    "\n",
    "#### List of bug fixes and enhancements\n",
    "* Clarifies that the classifier will learn to classify regions as either red or blue.\n",
    "* compute_cost function fixes np.squeeze by casting it as a float.\n",
    "* compute_cost instructions clarify the purpose of np.squeeze.\n",
    "* compute_cost clarifies that \"parameters\" parameter is not needed, but is kept in the function definition until the auto-grader is also updated.\n",
    "* nn_model removes extraction of parameter values, as the entire parameter dictionary is passed to the invoked functions."
