nbgrader v0.5.0 released

[Jessica B. Hamrick]

Hi all,

I am excited to announce that the nbgrader v0.5.0 has been released! You can install it via pip:

    pip install -U nbgrader

And very shortly the conda package will be available on conda-forge as well.

nbgrader version 0.5.0 is another very large release with some very exciting new features! The highlights include:

• The formgrader is now an extension to the notebook, rather than a standalone service.
• The formgrader also includes functionality for running `nbgrader assign`, `nbgrader release`, `nbgrader collect`, and `nbgrader autograde` directly from the browser.
• A new command `nbgrader zip_collect`, which helps with collecting assignment files downloaded from a LMS.
• Hidden test cases are now supported.
• A lot of functionality has moved into standalone objects that can be called directly from Python, as well as a high-level Python API in `nbgrader.apps.NbGraderAPI` (see http://nbgrader.readthedocs.io/en/latest/api/high_level_api.html ).
• A new **Validate** notebook extension, which allows students to validate an assignment notebook from the notebook itself (this is equivalent functionality to the "Validate" button in the Assignment List extension, but without requiring students to be using the Assignment List).
• A new command `nbgrader db upgrade`, which allows you to migrate your nbgrader database to the latest version without having to manually execute SQL commands.
• New cells when using the Create Assignment extension will automatically given randomly generated ids, so you don't have to set them yourself.

- You can assign extra credit when using the formgrader.

**Important**: Users updating from 0.4.x to 0.5.0 should be aware that they will need to update their nbgrader database using `nbgrader db upgrade` and will need to reinstall the nbgrader extensions (see http://nbgrader.readthedocs.io/en/latest/user_guide/installation.html ). Additionally, the configuration necessary to use the formgrader with JupyterHub has changed, though it is now much more straightforward (see http://nbgrader.readthedocs.io/en/latest/configuration/jupyterhub_config.html ).
