nbgrader version 0.5.1 is a bugfix release mainly fixing an issue with the formgrader. The following PRs were merged:

• PR #792: Make sure relative paths to source and release dirs are correct
• PR #791: Use the correct version number in the docs

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 ).

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).
