- LookML source will only emit views that are reachable from explores while scanning your git repo. Previous behavior can be achieved by setting `emit_reachable_views_only` to False.
- LookML source will always lowercase urns for lineage edges from views to upstream tables. There is no fallback provided to previous behavior because it was inconsistent in application of lower-casing earlier.
- dbt config `node_type_pattern` which was previously deprecated has been removed. Use `entities_enabled` instead to control whether to emit metadata for sources, models, seeds, tests, etc.
- The DataHub Airflow lineage backend and plugin no longer support Airflow 1.x. You can still run DataHub ingestion in Airflow 1.x using the [PythonVirtualenvOperator](https://airflow.apache.org/docs/apache-airflow/1.10.15/_api/airflow/operators/python_operator/index.html?highlight=pythonvirtualenvoperator#airflow.operators.python_operator.PythonVirtualenvOperator).
- For any of the GraphQL search queries, the input no longer supports value but instead now accepts a list of values. These values represent an OR relationship where the field value must match any of the values.
- The dbt ingestion source's `disable_dbt_node_creation` and `load_schema` options have been removed. They were no longer necessary due to the recently added sibling entities functionality.
- The `snowflake` source now uses newer faster implementation (earlier `snowflake-beta`). Config properties `provision_role` and `check_role_grants` are not supported. Older `snowflake` and `snowflake-usage` are available as `snowflake-legacy` and `snowflake-usage-legacy` sources respectively.
-#5451`GMS_HOST` and `GMS_PORT` environment variables deprecated in `v0.8.39` have been removed. Use `DATAHUB_GMS_HOST` and `DATAHUB_GMS_PORT` instead.
-#5478 DataHub CLI `delete` command when used with `--hard` option will delete soft-deleted entities which match the other filters given.
-#5471 Looker now populates `userEmail` in dashboard user usage stats. This version of looker connnector will not work with older version of **datahub-gms** if you have `extract_usage_history` looker config enabled.
- The `should_overwrite` flag in `csv-enricher` has been replaced with `write_semantics` to match the format used for other sources. See the [documentation](https://datahubproject.io/docs/generated/ingestion/sources/csv/) for more details
- Closing an authorization hole in creating tags adding a Platform Privilege called `Create Tags` for creating tags. This is assigned to `datahub` root user, along
with default All Users policy. Notice: You may need to add this privilege (or `Manage Tags`) to existing users that need the ability to create tags on the platform.
- Refactored the `health` field of the `Dataset` GraphQL Type to be of type **list of HealthStatus** (was type **HealthStatus**). See [this PR](https://github.com/datahub-project/datahub/pull/5222/files) for more details.
-#4875 Lookml view file contents will no longer be populated in custom_properties, instead view definitions will be always available in the View Definitions tab.
-#5208`GMS_HOST` and `GMS_PORT` environment variables being set in various containers are deprecated in favour of `DATAHUB_GMS_HOST` and `DATAHUB_GMS_PORT`.
-`KAFKA_TOPIC_NAME` environment variable in **datahub-mae-consumer** and **datahub-gms** is now deprecated. Use `METADATA_AUDIT_EVENT_NAME` instead.
-`KAFKA_MCE_TOPIC_NAME` environment variable in **datahub-mce-consumer** and **datahub-gms** is now deprecated. Use `METADATA_CHANGE_EVENT_NAME` instead.
-`KAFKA_FMCE_TOPIC_NAME` environment variable in **datahub-mce-consumer** and **datahub-gms** is now deprecated. Use `FAILED_METADATA_CHANGE_EVENT_NAME` instead.
-#5132 Profile tables in `snowflake` source only if they have been updated since configured (default: `1`) number of day(s). Update the config `profiling.profile_if_updated_since_days` as per your profiling schedule or set it to `None` if you want older behaviour.
- In this release we introduce a brand new Business Glossary experience. With this new experience comes some new ways of indexing data in order to make viewing and traversing the different levels of your Glossary possible. Therefore, you will have to [restore your indices](https://datahubproject.io/docs/how/restore-indices/) in order for the new Glossary experience to work for users that already have existing Glossaries. If this is your first time using DataHub Glossaries, you're all set!
-#4961 Dropped profiling is not reported by default as that caused a lot of spurious logging in some cases. Set `profiling.report_dropped_profiles` to `True` if you want older behaviour.
-#4875 Lookml view file contents will no longer be populated in custom_properties, instead view definitions will be always available in the View Definitions tab.
-#4760`check_role_grants` option was added in `snowflake` to disable checking roles in `snowflake` as some people were reporting long run times when checking roles.
