Seq 2021.3 previews now available

The first 2021.3 preview builds are now live on and Docker Hub. Along with some other improvements, they include the very first pieces of clustered Seq: disaster recovery (DR) and zero-downtime upgrades through asynchronous replication.

Cluster-aware functionality is behind a feature flag and will ship with "preview" status in the 2021.3 release, but, you can check out the setup guide now and give it a try - we'd love to hear your thoughts and first impressions! Contact us via if you'd like to schedule some time for us to walk you through it.

The full release contents are being tracked in this GitHub milestone, and we'll keep posting updates over there. 👋
