In accordance with the plans announced at Upcoming changes to Aggregate, the core team is no longer updating Aggregate. We will not fix bugs, add features, review PRs, improve documentation, release new versions, or answer support questions.
Thanks to all that have contributed to Aggregate over the years. We couldn't have come this far without you!
P.S. If you'd like to stay up-to-date on other end of life announcements, watch the end-of-life tag.
