nbgrader v0.4.0 pre-release

[Jessica B. Hamrick]

Hi all,

I am happy to announce that we are coming down the home stretch to release the next major version of nbgrader! nbgrader version 0.4.0 is a substantial release with lots of changes and several new features. As such, we are creating a pre-release version first to catch any remaining issues before the official release. To install the prerelease, run:

pip install -U nbgrader --pre

And please report any issues that you run into here: https://github.com/jupyter/nbgrader/issues/new

Importantly, users updating from 0.3.x to 0.4.0 should be aware that:

• You will need to update the metadata in your assignments using `nbgrader update`
• You will need to reinstall the nbgrader extensions (see http://nbgrader.readthedocs.io/en/0.4.x/user_guide/installation.html)
• The configuration necessary to use the formgrader with JupyterHub has changed, though it is now much less brittle (see http://nbgrader.readthedocs.io/en/0.4.x/configuration/jupyterhub_config.html).
  

 The highlights of 0.4.0 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 documentation

Cheers,

Jess
