Auto-generated tagged releases, and release notes (from GitHub issues).

fastrelease provides two commands that you can run from your shell:

  • nbdev_changelog: creates a file from closed and labeled GitHub issues
  • nbdev_tag_release: tags and creates a release in GitHub for the current version.

Be sure to check out the full documentation at Here's a brief demonstration of how to use fastrelease. This demo first creates an issue using the gh command line tool, and then closes it using git; you can also use GitHub's web interface for both of these tasks.


fastrelease has only one small prerequisite (fastcore) and will run on Python 3.6 or later. You can install from pip:

pip install fastrelease

...or conda:

conda install -c fastai fastrelease

How to use

Set up

First, create a settings.ini file with the following contents (replacing the values as described below):

lib_name = fastrelease
user = fastai
version = 0.0.1

Set lib_name to the name of GitHub repo, user to the owner of that repo, and version to the version number of your library. (Note that if you use nbdev then you'll already have this information, so you don't need to do anything further to set it up.)

You'll need to get a GitHub personal access token if you haven't already. To do so, click here and enter "fastrelease" in the "Note" section, and click the repo checkbox.

Then click "Generate Token" at the bottom of the screen, and copy the token (the long string of letters and numbers shown). You can easily do that by clicking the little clipboard icon next to the token.

Copying your token
Copying your token

Paste that token into a file called token into the root of your repo. You can run the following in your terminal (cd to the root of your repo first) to create that file:

echo XXX > token

Replace XXX above with the token you copied. Also, ensure that this file isn't added to git, by running this in your terminal:

echo token >> .gitignore

Creating release notes

Now you're ready to create your release notes. These are created in a file called Here's an example of what it creates: nbdev CHANGELOG.

All issues with the label bug, enhancement, or breaking that have been closed in your repo since your last release will be added to the top of this file. If you haven't made any releases before, then all issues with those labels will be included.

Therefore, before you create or update, go to your GitHub issues page, remove is:open from the filter, and label any issues you want included with one of the labels above. When you've done that, you can create or update your release notes by running in your terminal:


The titles and bodies of each issue will be added. Open in your editor and make any edits that you want, and then commit the file to your repo (remember to git add it!)

Tagging a release

You should now tag a release. This will create a tag in GitHub with your current version number in settings.ini, and will then make it into a release, using your latest release notes as the description of the release:


After you run this, be sure to increment your version number in settings.ini. You can either edit it manually, or if you use nbdev it can be done for you by running:


Doing both (creating release notes, and tagging a release)

To complete both of the steps above, run:


See the screencast above for a demonstration of this.
