Supabase Storage is receiving a significant upgrade, incorporating many of the most requested features from users. These include Resumable Uploads, Quality Filters, Next.js support, and WebP support. The key feature is Resumable Uploads, which allows for continued uploading even if internet connectivity is lost or accidentally closed during the process. Storage v3 introduces additional new features such as more image transformation options, a Next.js loader, presigned upload URLs, and size and file type limits per bucket. The upgrade also includes a deep dive into Resumable Uploads and how they were implemented using TUS (The Upload Server), an open protocol for resumable file uploads.
