124 * Added support for configurable user-supplied `Jinja
125 <http://jinja.pocoo.org/>`_ HTML templates for the notebook. Paths to
126 directories containing template files can be specified via
127 ``NotebookApp.extra_template_paths``. User-supplied template directories
128 searched first by the notebook, making it possible to replace existing
129 templates with your own files.
130
131 For example, to replace the notebook's built-in ``error.html`` with your own,
132 create a directory like ``/home/my_templates`` and put your override template
133 at ``/home/my_templates/error.html``. To start the notebook with your custom
134 error page enabled, you would run::
135
136 ipython notebook '--extra_template_paths=["/home/my_templates/"]'
137
138 It's also possible to override a template while also `inheriting
139 <http://jinja.pocoo.org/docs/dev/templates/#template-inheritance>`_ from that
140 template, by prepending ``templates/`` to the ``{% extends %}`` target of
141 your child template. This is useful when you only want to override a
142 specific block of a template. For example, to add additional CSS to the
143 built-in ``error.html``, you might create an override that looks like::
144
145 {% extends "templates/error.html" %}
146
147 {% block stylesheet %}
148 {{super()}}
149 <style type="text/css">
150 /* My Awesome CSS */
151 </style>
152 {% endblock %}

154 * Added a widget persistence API. This allows you to persist your notebooks interactive widgets.
155 Two levels of control are provided:
156 1. Higher level- ``WidgetManager.set_state_callbacks`` allows you to register callbacks for loading and saving widget state. The callbacks you register are automatically called when necessary.
157 2. Lower level- the ``WidgetManager`` Javascript class now has ``get_state`` and ``set_state`` methods that allow you to get and set the state of the widget runtime.
158
159 Example code for persisting your widget state to session data::
160
161 %%javascript
162 require(['widgets/js/manager'], function(manager) {
163 manager.WidgetManager.set_state_callbacks(function() { // Load
164 return JSON.parse(sessionStorage.widgets_state || '{}');
165 }, function(state) { // Save
166 sessionStorage.widgets_state = JSON.stringify(state);
167 });
168 });
169
170 * Enhanced support for :magic:`env` magic. As before, :magic:`env` with no
171 arguments displays all environment variables and values. Additionally,
172 :magic:`env` can be used to get or set individual environment variables. To
173 display an individual value, use the `%env var` syntax. To set a value, use
174 `env var val` or `env var=val`. Python value expansion using `$` works as usual.

233 * The notebook now uses a single websocket at `/kernels/<kernel-id>/channels` instead of separate
234 `/kernels/<kernel-id>/{shell|iopub|stdin}` channels. Messages on each channel are identified by a
235 `channel` key in the message dict, for both send and recv.
