**Type:** Announcement

## Summary

The September 2021 beta update for Supabase outlines several product enhancements, documentation revamps, and community milestones. Developers using the JavaScript library can now leverage AbortController support to cancel long-running queries. Multiple PostgreSQL capabilities have been surfaced directly within the Supabase Dashboard, allowing users to apply custom column types, configure unique constraints on tables, view and edit columns in bulk, and manage table relationships spanning multiple schemas. In addition, the authentication documentation has been restructured into dedicated sections for Authentication and Authorization alongside an accompanying deep dive series. The update also marks two years since the initial commit to the Realtime Postgres engine, details upcoming events such as a Hacktoberfest hackathon, and announces open hiring for Site Reliability Engineers.

## Context

Supabase reached two years since the first commit to its Realtime engine for Postgres and sought to improve developer user experience, documentation structure, and PostgreSQL feature accessibility.

## Approach / What changed

Supabase integrated AbortController support into its JavaScript library, updated the Dashboard with custom column types, table unique constraints, bulk column editing, and multi-schema relationships, and divided its auth documentation into Authentication and Authorization sections.

## Takeaways
