+## dbt-core 1.3.0-rc1 - September 28, 2022
+
+### Breaking Changes
+
+- Renaming Metric Spec Attributes ([#5774](https://github.com/dbt-labs/dbt-core/issues/5774), [#5775](https://github.com/dbt-labs/dbt-core/pull/5775))
+
+### Features
+
+- merge_exclude_columns for incremental materialization ([#5260](https://github.com/dbt-labs/dbt-core/issues/5260), [#5457](https://github.com/dbt-labs/dbt-core/pull/5457))
+- Search current working directory for `profiles.yml` ([#5411](https://github.com/dbt-labs/dbt-core/issues/5411), [#5717](https://github.com/dbt-labs/dbt-core/pull/5717))
+- Adding the `window` parameter to the metric spec. ([#5721](https://github.com/dbt-labs/dbt-core/issues/5721), [#5722](https://github.com/dbt-labs/dbt-core/pull/5722))
+- Add invocation args dict to ProviderContext class ([#5524](https://github.com/dbt-labs/dbt-core/issues/5524), [#5782](https://github.com/dbt-labs/dbt-core/pull/5782))
+- Adds new cli framework ([#5526](https://github.com/dbt-labs/dbt-core/issues/5526), [#5647](https://github.com/dbt-labs/dbt-core/pull/5647))
+- Flags work with new Click CLI ([#5529](https://github.com/dbt-labs/dbt-core/issues/5529), [#5790](https://github.com/dbt-labs/dbt-core/pull/5790))
+- Add metadata env method to ProviderContext class ([#5522](https://github.com/dbt-labs/dbt-core/issues/5522), [#5794](https://github.com/dbt-labs/dbt-core/pull/5794))
+- Array macros ([#5520](https://github.com/dbt-labs/dbt-core/issues/5520), [#5823](https://github.com/dbt-labs/dbt-core/pull/5823))
+- Add enabled config to exposures and metrics ([#5422](https://github.com/dbt-labs/dbt-core/issues/5422), [#5815](https://github.com/dbt-labs/dbt-core/pull/5815))
+- add -fr flag shorthand ([#5878](https://github.com/dbt-labs/dbt-core/issues/5878), [#5879](https://github.com/dbt-labs/dbt-core/pull/5879))

+- This conditionally no-ops warehouse connection at compile depending on an env var, disabling introspection/queries during compilation only. This is a temporary solution to more complex permissions requirements for the semantic layer. ([#5936](https://github.com/dbt-labs/dbt-core/issues/5936), [#5926](https://github.com/dbt-labs/dbt-core/pull/5926))
+

+- ConfigSelectorMethod should check for bools ([#5890](https://github.com/dbt-labs/dbt-core/issues/5890), [#5889](https://github.com/dbt-labs/dbt-core/pull/5889))

+## dbt-core 1.3.0-rc1 - September 28, 2022
+
+### Breaking Changes
+
+- Renaming Metric Spec Attributes ([#5774](https://github.com/dbt-labs/dbt-core/issues/5774), [#5775](https://github.com/dbt-labs/dbt-core/pull/5775))
+
+### Features
+
+- merge_exclude_columns for incremental materialization ([#5260](https://github.com/dbt-labs/dbt-core/issues/5260), [#5457](https://github.com/dbt-labs/dbt-core/pull/5457))
+- Search current working directory for `profiles.yml` ([#5411](https://github.com/dbt-labs/dbt-core/issues/5411), [#5717](https://github.com/dbt-labs/dbt-core/pull/5717))
+- Adding the `window` parameter to the metric spec. ([#5721](https://github.com/dbt-labs/dbt-core/issues/5721), [#5722](https://github.com/dbt-labs/dbt-core/pull/5722))
+- Add invocation args dict to ProviderContext class ([#5524](https://github.com/dbt-labs/dbt-core/issues/5524), [#5782](https://github.com/dbt-labs/dbt-core/pull/5782))
+- Adds new cli framework ([#5526](https://github.com/dbt-labs/dbt-core/issues/5526), [#5647](https://github.com/dbt-labs/dbt-core/pull/5647))
+- Flags work with new Click CLI ([#5529](https://github.com/dbt-labs/dbt-core/issues/5529), [#5790](https://github.com/dbt-labs/dbt-core/pull/5790))
+- Add metadata env method to ProviderContext class ([#5522](https://github.com/dbt-labs/dbt-core/issues/5522), [#5794](https://github.com/dbt-labs/dbt-core/pull/5794))
+- Array macros ([#5520](https://github.com/dbt-labs/dbt-core/issues/5520), [#5823](https://github.com/dbt-labs/dbt-core/pull/5823))
+- Add enabled config to exposures and metrics ([#5422](https://github.com/dbt-labs/dbt-core/issues/5422), [#5815](https://github.com/dbt-labs/dbt-core/pull/5815))
+- add -fr flag shorthand ([#5878](https://github.com/dbt-labs/dbt-core/issues/5878), [#5879](https://github.com/dbt-labs/dbt-core/pull/5879))
+- add type_boolean as a data type macro ([#5739](https://github.com/dbt-labs/dbt-core/issues/5739), [#5875](https://github.com/dbt-labs/dbt-core/pull/5875))
+- Support .dbtignore in project root to ignore certain files being read by dbt ([#5733](https://github.com/dbt-labs/dbt-core/issues/5733), [#5897](https://github.com/dbt-labs/dbt-core/pull/5897))
+- This conditionally no-ops warehouse connection at compile depending on an env var, disabling introspection/queries during compilation only. This is a temporary solution to more complex permissions requirements for the semantic layer. ([#5936](https://github.com/dbt-labs/dbt-core/issues/5936), [#5926](https://github.com/dbt-labs/dbt-core/pull/5926))
+

+- ConfigSelectorMethod should check for bools ([#5890](https://github.com/dbt-labs/dbt-core/issues/5890), [#5889](https://github.com/dbt-labs/dbt-core/pull/5889))

+
+### Under the Hood
+
+- Migrate integration test 014 but also fix the snapshot hard delete test's timezone logic and force all integration tests to run flags.set_from_args to force environment variables are accessible to all integration test threads.
