 # Changelog
 
+## [1.0.0](https://github.com/forcedotcom/datacloud-jdbc/compare/v0.42.2...v1.0.0) (2026-05-22)
+
+
+### ⚠ BREAKING CHANGES
+
+* `DataCloudResultSet` is now a class instead of an interface; `StreamingResultSet`, `DataCloudMetadataResultSet`, `SimpleResultSet`, `ColumnAccessor` are removed; metadata int-column `getDate`/`getTime`/`getTimestamp` throw `SQLException` (was `UnsupportedOperationException`); `getTypeInfo()` boolean columns are typed `BOOLEAN` instead of `VARCHAR` (`getObject` returns `Boolean`, not `String`); `getColumnTypeName` on metadata result sets returns the JDBC type name (`VARCHAR`/`SMALLINT`/`INTEGER`/`BOOLEAN`) instead of the prior Hyper-flavored labels (`TEXT`/`SHORT`/`INTEGER`/`BOOL`); `ps.setObject` with `Types.VARCHAR` rejects non-String/byte[] payloads; integer-family and DECIMAL setters reject out-of-range values instead of silently narrowing.
+
