Supabase has introduced new features for its Edge Functions, including background tasks, ephemeral storage, and WebSocket support. Background tasks can run for a limited duration depending on the plan, and a new method, EdgeRuntime.waitUntil, ensures that tasks are completed before termination. Edge Functions can now handle inbound and outbound WebSocket connections, enabling secure implementation of use cases like OpenAI's Realtime API relay. Several performance and stability improvements have also been made recently.
