+- **Metadata Docker CLI**: For the past releases, we have been updating the documentation to point users to directly run the docker quickstart
+  with the docker compose files in the release page ([docs](quick-start/local-docker-deployment)). In this release, we're completely removing the support for `metadata docker`.
+- **Metadata Backup & Restore**: On the `metadata` CLI, we are deprecating the `backup` and `restore` commands, since users can now completely
+  rely on native database tools both for MySQL and PostgreSQL. Check the [docs](/deployment/backup-restore-metadata)
+  for more information
+- **bootstrap_storage.sh**: `bootstrap/bootstrap_storage.sh` now deprecated in favor of `bootstrap/openmetadata-ops.sh`, please refer to help docs of the new tool for any changes.

+### UI
 
-### Metadata Backup & Restore
+- **Activity Feed**: Activity is Improved, new Update specific cards will be showing critical information such as data quality test case updates, description, tag update or removal
+- **Lineage**: The `Expand All` button is removed. Instead, the new `Layers` button has been introduced to the bottom left corner. 
+  Please use Layers to add Column Level Lineage or Data Observability details to your Lineage view.
+- **View Definition**: View Definition is now renamed to Schema Definition
+- **Glossary**: Adding a Glossary Term view has improved. Now, we show glossary terms hierarchically,
+  enabling a better understanding how the terms are set up while adding it to a table or dashboard.
+- **Classifications**: Users can set a classification to be mutually exclusive **only** at the creation time. 
+  Once created, you cannot change it back to non-mutually exclusive or vice-versa. 
+  This is to prevent conflicts of adding multiple tags that belong to same classification and later turning the mutually exclusive flag back to true.
