Highlights since 350-e#

Breaking changes#

This release includes no breaking changes since the 355-e release. However like 354-e and all future SEP releases, it is based on Trino. It is therefore the first LTS release based on Trino.

All breaking changes from 354-e and the tips from the migration guide apply. It is important that you review these if you are upgrading from 350-e or an earlier release.
