+# 🧪 Mathesar 0.2.0-testing.1
+
+!!! danger "Not a stable release"
+    This is a testing build released with the goal of gathering feedback from our community. It has **[many known issues](https://github.com/mathesar-foundation/mathesar/issues?q=is%3Aissue+milestone%3Av0.2.0-testing.2+)** and is not recommended for production use.
+
+## Summary
+
+**Mathesar 0.2.0-testing.1** provides an early preview of improvements we plan to release in our beta version. We have a brand new access control system based entirely on PostgreSQL database permissions, and we've also made major improvements to the responsiveness of the Mathesar UI. We've also built out a new RPC API, and we're deprecating our REST API in favor of it.
+
+_This page provides a comprehensive list of all changes in the release._
+
+## Installing 0.2.0-testing.1
+
+You will need to create a new installation of Mathesar to use this version, which you can do via [Docker Compose](../installation/docker-compose/index.md) or [from source](../installation/build-from-source/index.md).
+
+We do not support upgrading from previous versions to `0.2.0-testing.1`. 
+
+## Improvements
+
+### Access control based on PostgreSQL roles and privileges
+
+We have a brand new access control system based entirely on PostgreSQL database roles and privileges. Mathesar users must now be assigned a database role, and any operations performed by the user through the Mathesar UI will connect to the database using that role. 
+
+![image](../assets/releases/0.2.0-testing.1/db-settings-collaborators.png)
+
+This gives Mathesar several new capabilities. Database administrators can set up access control directly on the database and use those roles in Mathesar. Mathesar also supports setting up PostgreSQL roles and privileges via the UI, including granular access control at the individual table level.
+
+This replaces our previous access control system (which was enforced at the API layer, and only supported permissions at the database and schema levels). It also eliminates the need for Mathesar to use a database superuser for day-to-day operations.
+
+More detailed documentation can be found in our User Guide under [Permissions](../user-guide/permissions.md) and [Users](../user-guide/users.md).

+### Performance improvements and RPC API
+
+We've made major improvements to the responsiveness of the Mathesar UI. Loading data and data entry should be much more snappy, and importing data into Mathsar is around 50 times faster. We've also eliminated the need to manually sync database schema changes to Mathesar, any DDL changes will be reflected in the UI automatically.
+
+To achieve these performance benefits, we needed to overhaul our backend architecture and API. We have built out a new RPC API and our frontend UI now primarily uses that API. The RPC API [has some documentation here](../api/rpc.md), but should not be considered stable yet.
+
+Most of our REST API endpoints are now deprecated and will be removed soon. The `/users/` and `/data-files/` endpoints remain in use.

+### Visual improvements
+
+We made several visual improvements to Mathesar to ensure consistency, better usability, and adherence to design guidelines. The changes were mainly to various modals and to the table inspector.

+## Live demo changes
+
+We have removed code related to Mathesar's "live demo" mode since we didn't think it made sense to include code for our promotional website in the core product. If we do choose to maintain our live demo in the future, we will set up a separate microservice that performs some of these functions.
+
+We also set up a workflow to reset the live demo regularly to mitigate reliability issues.
