Supabase, an open-source PostgreSQL database service, has released version 1.0 of its supabase-js client libraries with significant developer experience improvements. The SQL Editor feature has been updated with tabs and full-screen capabilities, and key commands have been added for power users. Magic Links, a highly requested Auth feature, allows users to log in using magic links. Additionally, Supabase's dashboard performance has been optimized, and the community contributed significantly during Hacktoberfest. The focus now is on moving from Alpha to Beta, improving stability, reliability, and performance.
