## Generating the Changelog
We use [github-changelog-generator](https://github.com/github-changelog-generator/github-changelog-generator) to 
generate release Changelogs. To be consistent with previous Changelogs, the following flags should be passed to the 
command:

```
--user vulcanize
--project vulcanizedb
--token {YOUR_GITHUB_TOKEN}
--no-issues
--usernames-as-github-logins
--since-tag {PREVIOUS_RELEASE_TAG}
```

More information on why your github token is needed, and how to generate it here:https://github
