# 9.1.0

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.

# 9.0.0 - Core dependency & repo urls

We discovered that `primer-core` specified and outdated version of `primer-base` in it's dependencies. The outdated version did not have `normalize.scss` included which could cause some issues. This has issue occurred during v7.0.0 when creating the new monorepo. Also fixes repo urls in `package.json` for individual packages.

See PR [#243](https://github.com/primer/primer/pull/243)

# 8.0.0 - Imports

Fixes issues with the ordering of imports in each of our meta-packages. See PR [#239](https://github.com/primer/primer/pull/239)


## Changes

### Primer Core v5.0.1
- Re-ordered imports in `index.scss` to ensure utilities come last in the cascade

### Primer Product v5.0.1
- Re-ordered imports in `index.scss` to move markdown import to end of list to match former setup in GitHub.com

### Primer Marketing v5.0.1
- Re-ordered imports in `index.scss` to ensure marketing utilities come last in the cascade

# 7.0.0 - Monorepo

In an effort to improve our publishing workflow we turned Primer into a monorepo, made this repo the source of truth for Primer by removing Primer modules from GitHub, and setup Lerna for managing multiple packages and maintaining independent versioning for all our modules.

This is exciting because:

- we can spend less time hunting down the cause of a broken build and more time focussing on making Primer more useful and robust for everyone to use
- we can be more confident that changes we publish won't cause unexpected problems on GitHub.com and many other GitHub websites that use Primer
- we no longer have files like package.json, scripts, and readme's in the GitHub app that don't really belong there
- **we can accept pull requests from external contributors** again!

See PR for more details on this change: https://github.com/primer/primer/pull/230
