- Add `test-docs` npm script in each module to check that every CSS class is documented (or at least mentioned) in the module's own markdown docs
## Changes
- Remove per-module configurations (`.gitignore`, `.postcss.json`, `.stylelintrc.json`) and `CHANGELOG.md` files in #284
- Replace most static `font-size`, `font-weight`, and `line-height` CSS property values with their [SCSS variable equivalents](https://github.com/primer/primer-css/blob/c9ea37316fbb73c4d9931c52b42bc197260c0bf6/modules/primer-support/lib/variables/typography.scss#L12-L33) in #252
- Refactor CI scripts to use Travis conditional deployment for release candidate and final release publish steps in #290
This release updates our [stylelint config](/primer/stylelint-config-primer) to [v2.0.0](https://github.com/primer/stylelint-config-primer/releases/tag/v2.0.0), and to stylelint v7.13.0. Each module also now has a `lint` npm script, and there are top-level `test` and `lint` scripts that you can use to lint and test all modules in one go.
This release also includes major improvements to our Travis build scripts to automatically publish PR builds, release candidates, and the "final" versions to npm.
