What's new in 5.2 New

Why upgrade?

  • Companion broker New in 5.2 - a self-hosted Node/Express OAuth and file-proxy broker (multipleupload/server/companion) that keeps provider client secrets and access tokens server-side, with proxy and server-to-destination transfer modes. Zero new dependencies.
  • 6 cloud sources New in 5.2 - Drive, Dropbox, OneDrive, Box (now first-class), Unsplash (search and import), and the Companion broker.
  • Headless framework hooks New in 5.2 - useUploader() for React and Vue, use:uploader for Svelte, UploaderService for Angular, for fully custom UI.
  • Content-aware image editor New in 5.2 - focal-point smart-crop, text and sticker overlays, filter presets, EXIF info panel, and AVIF/WebP output with a quality slider. Plus the IImageTransformer server-side extension point.
  • 7 transport strategies - single / chunked / s3 / azure / gcs / tus / urlImport, swappable via one Strategy option.
  • 4 cloud-source pickers - let users import from Google Drive, OneDrive, Dropbox, and Box without leaving your page.
  • Encryption-at-rest - AES-GCM-256 (Web Crypto) protects browser-side queued and resumed files; zero-knowledge upload to your storage.
  • Offline-first queueing - service worker persists the queue across tab close and network loss; resumes automatically on reconnect.
  • Cross-tab dashboard - coordinated upload state across browser tabs via BroadcastChannel.
  • Virus-scan hook - new /scan endpoint + OnFileUploaded integration for ClamAV, Defender, or any scanner CLI.
  • 28 built-in locales - includes RTL Arabic, Hebrew, and Persian.
  • Image pipeline - inline annotation, HEIC auto-decode, and 5 preset sizes ready to drop in.
  • PDF + video lightbox preview, composable UI primitives, and drag-to-reorder queue.
  • Pluggable provider interfaces - IS3Signer, IAzureSigner, IGcsSigner for clean server-side credential brokering.
  • Direct-to-cloud multipart - browser uploads straight to Amazon S3, MinIO, R2, B2, Azure Blob, or GCS via presigned URLs. Bytes bypass IIS entirely.
  • IndexedDB-backed resume - uploads survive tab crashes and page reloads; chunked, s3, azure, gcs, and tus strategies all rehydrate from the last completed part.
  • Full backward compatibility - CuteWebUI namespace shim keeps existing 4.x pages compiling unchanged.
  • Comprehensive class reference documentation.
Do I qualify for the upgrade price?

Yes, if you hold any valid AjaxUploader 4.x license. The upgrade price corresponds to your current license type.

Will my existing code still work?

Yes — and the important part is what not to change. Keep your existing <CuteWebUI:Uploader> / <CuteWebUI:UploadAttachments> markup and your FileUploaded, Items and args.OpenStream() code exactly as they are: the CuteWebUI namespace in 5.3 is the drop-in path, with every 4.x property, event and client-side hook (getqueuecount(), CuteWebUI_AjaxUploader_OnPostback) verified against the 4.0 assembly. Reference CuteWebUI.AjaxUploader.dll from the package's legacy/ folder alongside AjaxUploader.dll.

The <au:> tags you see across the demos are the new API for new pages. Do not port working 4.x pages to them just to upgrade — that rewrite is where upgrades go wrong, and it is optional. See the v4 compatibility demos (the 4.0 sample pages running unmodified on 5.3) and the migration guide.
