Upload

[RC] Latest Beta or Release Candidate

[4.2.1] - 2026-03-04

Fixed

• (internal) Configurable storage class from env variable

[4.2.0] - 2026-03-02

Added

• File extension is appended to uploaded file paths based on detected MIME type across all upload routes (/upload/raw, /upload/image-data-uri, /upload/file)
• Content-based MIME type detection (stream sniffing) when Content-Type is missing or is application/octet-stream — supports PNG, JPEG, WebP, BMP, and TIFF signatures

[4.1.0] - 2026-02-27

Added

• Saving screenshots to S3 with storage class STANDARD_IA

[4.0.1] - 2026-01-14

Fixed

• Graceful shutdown works again. When the service is stopping, it will drain all pending requests before exiting.
• Add keepAlive to fix 502 errors when running with AWS ALB

[4.0.0] - 2026-01-07

Changed

• Offline actions files are processed directly by this service instead of uploading them to the storage. The response still contains an URI for BC but it's an empty string and not intended to use anymore.

Removed

• Storage type local - it wasn't used anymore
• Storage type rsync - it wasn't used anymore
• Storage type queue-static-file - it wasn't used anymore

Fixed

• Uploading files via endpoint POST /upload/file is more efficient as it streams files directly to the destination instead of saving them to the local file system first

[3.5.2] - 2024-12-11

Fixed

• Removed vulnerable library image-data-uri and fix its usage with own implementation of image data URI decoding

[3.5.1] - 2024-12-06

Fixed

• Re-implementation of S3 storage using wrapper class from @signageos/lib (which made it possible to get rid of the aws-sdk dependency)

[3.5.0] - 2024-10-03

Added

• Added this changelog line to be able create tag with no real changes (hacked pipeline, hacked changelog). Should be one time occurrence

[3.4.0] - 2024-10-03

Added

• Added support for sessionId route suffix, which can be used for upload authorization during remote desktop session. The functionality is off by default. That solves backwards compatibility of standalone Upload service and usage of this lib in other usecases.
