Issues & Discussions

We are using GitHub discussions as the place for issue discussion and feature requests. As discussions mature into action items, we will add those items as issues. This helps us ensure that issues in the issue tracker are well-understood, deduplicated, and actionable. For these reasons, please do NOT open issues directly.

Contributing

We unfortunately don't have the bandwidth to support review of external contributions, and we don't want user PRs to languish, so we aren't accepting any external contributions right now.

If you have a great idea or pain point, we would love to hear about it on our discussions page - the preferred place for issue discussion and feature requests.
