 ## [Unreleased]
 
+### Added

+- Trino support through a downloadable native Swift driver. Connect over the HTTP client protocol with a username and password or a JWT token, browse catalogs, schemas, tables, materialized views, and columns, run SQL and EXPLAIN, edit rows, and create or alter tables. TLS supports Verify CA and Verify Identity with a custom CA certificate, and client certificates for mutual TLS. Large exports stream page by page. (#1906)
