Hello!

We will be upgrading Presto to version 0.273.3 on Wednesday July 6th. This will require a restart of the Presto cluster. Any running queries may be interrupted, but we don't expect any issues aside from that.

If you notice any new problems with Superset dashboards that use Presto, after we do this upgrade, please let us know. Rolling back is relatively easy.

We will announce again here once the upgrade is complete. You can follow along at https://phabricator.wikimedia.org/T311525
