+## dbt-postgres 1.9.0 - December 09, 2024
+
+### Breaking Changes
+
+- Drop support for Python 3.8 ([#161](https://github.com/dbt-labs/dbt-postgres/issues/161))
+
+### Features
+
+- Add tests for cross-database `cast` macro ([#76](https://github.com/dbt-labs/dbt-postgres/issues/76))
+- Cross-database `date` macro ([#82](https://github.com/dbt-labs/dbt-postgres/issues/82))
+- Add support for Python 3.12 ([#17](https://github.com/dbt-labs/dbt-postgres/issues/17))
+- Allow configuring snapshot column names ([#144](https://github.com/dbt-labs/dbt-postgres/issues/144))
+- Microbatch incremental strategy implementation: merge ([#149](https://github.com/dbt-labs/dbt-postgres/issues/149))
+- Enable setting current value of dbt_valid_to ([#151](https://github.com/dbt-labs/dbt-postgres/issues/151))
+
+### Fixes
+
+- Fix the semicolon semantics for indexes while respecting other bug fix ([#85](https://github.com/dbt-labs/dbt-postgres/issues/85))
+- Default to psycopg2-binary and allow overriding to psycopg2 via DBT_PSYCOPG2_NAME (restores previous behavior) ([#96](https://github.com/dbt-labs/dbt-postgres/issues/96))
+- Fix `persist_docs` for `materialized_view` materializations. Previously, using this configuration with materialized view models would lead to an error. ([#120](https://github.com/dbt-labs/dbt-postgres/issues/120))
+
+### Under the Hood
+
+- Add support for experimental record/replay testing. ([#123](https://github.com/dbt-labs/dbt-postgres/issues/123))
+- Updating changie.yaml to add contributors and PR links ([#109](https://github.com/dbt-labs/dbt-postgres/issues/109))
