nbgrader v0.4.0

[Jessica B. Hamrick]

Hi all,

I am happy to announce that nbgrader v0.4.0 has officially been released! You can install it with:

pip install -U nbgrader

(The conda version of nbgrader is currently being built and will be available in the next day or so.)

nbgrader version 0.4.0 is a substantial release with lots of changes and several new features. The highlights include:

• Addition of a command to modify students and assignments in the database (nbgrader db)
• Validation of nbgrader metadata, and a command to automatically upgrade said metadata from the previous version (nbgrader update)
• Support for native Jupyter nbextension and serverextension installation, and deprecation of the nbgrader nbextension command
• Buttons to reveal students' names in the formgrader
• Better reporting of errors and invalid submissions in the "Assignment List" extension
• Addition of a menu to change between different courses in the "Assignment List" extension
• Support to run the formgrader as an official JupyterHub service
• More flexible code and text stubs when creating assignments
• More thorough documentations

Important: Users updating from 0.3.x to 0.4.0 should be aware that they will need to update the metadata in their assignments using nbgrader update and will need to reinstall the nbgrader extensions (see http://nbgrader.readthedocs.io/en/stable/user_guide/installation.html#nbgrader-extensions). Additionally, the configuration necessary to use the formgrader with JupyterHub has changed, though it is now much less brittle (see http://nbgrader.readthedocs.io/en/stable/configuration/jupyterhub_config.html).
