• PR has an informative and human-readable title
  • PR titles are used to generate the change log in releases; good ones make that easier to scan.
  • PRs will be broadly categorized in the change log, but for even easier scanning, consider prefixing with a component name or other useful categorization, e.g., "BaseButton: fix layout bug", or "Storybook: Update dependencies".
• PR has been tagged with a SemVer label and a general category label, or skip-changelog.
  • These tags are used to do the aforementioned broad categorization in the change log and determine what the next release's version number should be.
  • Release Drafter will attempt to do the category labeling for you! Please double-check its work.
