Supabase Auth`, a new feature, is being released after 5 months of development. The update aims to make it easy to implement an authentication system in apps using PostgreSQL's Row Level Security. A simple example and video tutorial are available to help developers get started. The Table Editor has been improved with the ability to drill into table relationships multiple levels deep and to add, delete, and download rows. Several new Postgres extensions have also been added, including `pgsql-http`, `pgjwt`, `plpgsql_check`, and `pljava`. Small improvements include updated documentation, a new filter in the client library, and enhanced performance. The update is now live, and developers can start using Supabase Auth today by visiting the dashboard at `supabase.com/dashboard`.
