 By default, every package with a changeset will be released. If you only want to target a smaller subset of packages for release, you can consider clearing out the `.changesets` directory to replace all existing changesets with a single changeset of only the packages that you want to release. Just be sure not to commit or push this to `main`, since it will destroy existing changesets that you will still want to eventually release.

 ### Releasing `astro@next` (aka "prerelease mode")
 
 Sometimes, the repo will enter into "prerelease mode". In prerelease mode, our normal release process will publish npm versions under the `next` dist-tag, instead of the default `latest` tag. We do this from time-to-time to test large features before sharing them with the larger Astro audience.
